Introduction to energy power meter:
In a house or in an establishment electrical power is used for various purposes. An agency supplies the electric power at a cost. How does the agency charge you?
The agency charges for the total electrical energy consumed over a period. The amount of electrical energy consumed from time to time is measured by an instrument called energy power meter. It is fitted near to mains connection of the user.Having problem with Phase Change Definition keep reading my upcoming posts, i will try to help you.
Description of energy power meter:
A schematic sketch of an energy power meter is shown above. Two cores of are wound with coils and separated by an electrical insulator. An aluminum disc is mounted on a spindle in such a way that it can rotate in between the coils. The aluminum disc also rotates in between a permanent magnet.
Is this topic Power Equation hard for you? Watch out for my coming posts.
Principle of energy power meter:
One of the coils is connected across the voltage of the supply and the other coil is connected in series with the line. Hence, the first coil produces a magnetic flux proportional to the voltage and the second coil produces a magnetic flux proportional to the current. These two magnetic fluxes are made to act at 90o and due to interaction of these two fluxes eddy current are induced in the aluminum disc. Hence the disc starts rotating.
The permanent magnet tries to oppose the rotation and at equilibrium, the disc rotaes at a speed proportional to the instantaneous power in the circuit.
The spindle is engaged to a set of worm gears which operate a set of tiny clocks. The clocks are calibrated in such a way to read the number of revolutions in ones, tens hundreds etc.

Persistence of Vision
Introduction to persistence of vision:
Persistence of vision is the theory or phenomenon which explains that our retains the image of whatever we see for almost 1/25 second or twenty-fifth of a second or 0.04 seconds. This retained image is called the after image.
So according to this theory of Persistence of vision whatever we see or observe is actually a subtle blend or mix of images at the intervals 0.04 seconds, (that is a blend of images of what is happening now and what had happened a fraction of second back.
The theory of persistence of vision is believed to have been discovered by Lucretius,a Roman poet, although he had mentioned about persistence of vision only in connection with images seen in dreams.
Now a days it has become a common belief of thinkers and scientists that this theory is just a myth.
Persistence of vision examples:
FILM SYSTEMS
A film or a video is made of of number of still images known as frames. This frames are played one after the other with an time interval of less than 0.04 seconds.
This is accounted on the basis of persistence of vision in human, because of which we retain the first frame seen till 0.04, and after 0.04 seconds our eye looks out for another frame of the video. So a frame is changed just in an interval of 0.04 seconds, and our eye observes this to be a continuous video or film.
Thus the minimum frame rate for a video to appear continuous is 25fps( frame per second)
Cartoon Animation
Cartoon animations are also made up of still images. In cartoons lesser number of frames are used each second.
Mostly they show the same drawing in two frames.That means for a cartoon animation having frame rate of 26fps, only 13 different drawings are shown.
Is Persistence of vision a myth:
In the year 1912 Theory of Persistence of vision was debunked, as their was no scientific proof to prove how this theory works.
Two modern theories that replaced this and have more scientifically strong base are Phi phenomenon and Beta movement.

Relative Magnetic Permeability
Introduction to relative magnetic permeability:
In electromagnetism (the branch of physics), the ability of a material which supports to produce the magnetic field within itself is called the permeability. We can say that the degree of magnetization of the material which responds to the magnetic filed is called the permeability. Oliver Heaviside gave the term permeability in 1885.
I like to share this Center of Mass of a Triangle with you all through my article.
Permeability for the explanation relative magnetic permeability:
The permeability is measured in Henry per metre or Newton per squared ampere. The absolute permeability of the free space is denoted by the µ0. The absolute permeability is also known as the magnetic constant of the free space. The permeability of the free space is the measure of amount of the resistance offered by the forming of magnetic field in vacuum. The value of the absolute permeability of free space is µ0 = 4p×10-7 H·m-1 or N·A-2. For example, if we rub the iron piece with the magnet, the iron piece gets magnetized and will have its own magnetic field. We can also define the magnetic permeability as the ratio of flux density to the magnetic filed strength (`mu` = B/ H).
Having problem with Force Formula keep reading my upcoming posts, i will try to help you.
Relative magnetic permeability:
The relative permeability is measured as the ratio of the permeability of the specific medium to the absolute permeability of the free space.
`mu`r = `mu` /`mu`0
The magnetic permeability is not a constant quantity. It is a unit less quantity because it is the ratio of same kind of the physical quantities. It changes as the position of the material changes in the magnetic field. The magnetic permeability also depends on the humidity and the temperature of the material. The materials having high relative permeability are used in strong electromagnets etc. The magnet weakly attracts the substances having low relative permeability. Ferro magnetic materials have high value of relative magnetic permeability. The magnetic materials which are diamagnetic in nature have low values of the relative permeability which are slightly less than 1. In case of the paramagnetic materials, the value of relative magnetic permeability is slightly greater than 1. For some of the materials such as pure iron, and some alloys have relative magnetic permeability more than 100000 or equal to 100000.

Examples of Gravitational Force
Introduction to Examples of Gravitational Force
Gravity is the force by which every object is attracted to the center of the earth.All heavenly bodies possess gravity at different rates.The gravity in moon is 1/80th the gravity on earth.
Let us take a look at certain examples of gravity
Examples of Gravitational Force
It is because of gravity that everything falls down to earth.If you throw up something, it returns back to the ground too.Everything returns to the earth at a rate of 9.8m/sec^2.An apple falling from a tree is a classical example which led Sir Issac Newton to the discovery of gravity.In the same way gravitational force attracts all body with mass towards the center of the earth.A falling stone,A falling ball,a falling star etc may be sited as examples.
Gravitational force helps in movement.It is because of the gravitational force that we can walk,run,jump etc on the surface of the earth.As said earlier,moon has 1/80th of gravitational force as that of earth, so a person who has 80 kg on earth would experience a weight of 1 kg in moon.This will make him float on the surface of moon.It is because of gravitational force that we move about on earth,it enables the movement of vehicles through the surface of earth too.If gravity was absent,then we would all float about on the surface of the earth.
Without gravity most of the games that we play today including football,soccer,running race,car race etc would not have been there and so does other day to day activities.It is the force of gravity which keeps the planets rotating and revolving around the sun,along with centripetal force.So gravity is indirectly responsible for the cause of day and night and also seasons.
Properties of Examples of Gravitational Force
Gravity is not uniform as it appears.Because the earth is lumpy and bumpy,the gravitational pull is stronger in some places than the others.For example,gravity in Rocky mountains is more than the gravity in Indian Ocean.
Gravity does not remain still too.It changes with ocean currents and magma flow beneath the earth crust,rainfall etc.

Oscillations Introduction
Introduction to oscillation:
In scientific way, there are numerous kinds of motion, such as linear motion, uniformly accelerated motion, non-uniform motion, circular motion, translatory motion, rotational motion, one dimensional motion, two dimensional motion, vibratory motion, periodic motion, oscillatory motion etc. Here we discuss the oscillatory motion.Please express your views of this topic Newtons 1st Law of Motion by commenting on blog.
Explanation and examples of oscillatory motion:
A motion that repeats itself repeatedly about its mean position, such that it remains confined within two well-defined limits (called extreme positions) on either side of the mean position or from the equilibrium, position is called oscillatory motion. It is also called as the vibratory motion. For example, the motion of the Halley’s comet, motion of the earth, phases of moon, the bob of the simple pendulum, the motion of the bar magnet when it is freely suspended.
Some of the common examples are as follows:
The liquid contained in a U tube is oscillatory if it is displaced by a small distance.
The motion of the loaded spring if it being displaced by a small distance.
When a small glass ball or the metallic ball is dropped along the walls of the bowl, it executes the oscillatory motion.
When a piece of wood floating over the surface of the liquid is pressed down and released, it executes oscillatory motion.
If a tunnel is dug along the diameter of the earth and a body is dropped in the tunnel, then the body will not come to rest at the centre of the earth. It will execute the oscillatory motion inside the tunnel about the centre of the earth.Is this topic Force Formula hard for you? Watch out for my coming posts.
Conclusion for oscillation:
We can conclude that the periodic motion or the bounded motion of a particle about its position may be called as the oscillatory motion. It easily follows that all oscillatory motion is periodic motion but not every periodic motion is oscillatory. Remember that the time taken to complete one oscillation by a body, which executes the oscillatory motion, is constant and that time is called the time-period. The reciprocal of the time-period is called frequency or the number of oscillations in one second is called frequency.

How to Calculate Potential Energy
Introduction to calculate potential energy:
Ever heard the term, "He has huge potential for development"? If you have heard of it then you probably know what it means. It means that whoever it is that is being referred to here, they have a huge capacity for development. The Potential part of Potential Energy has the same usage too.
The Potential Energy of a body refers to the Energy Capacity of a body, usually at rest. Depending upon the mass of the body we have a time tested formula for calculating the Potential Energy of a body. As a little byline, this term was coined by the physicist William Rankine.
Formula for Potential Energy
Suppose a body of mass M is at a height (or was lifted to that height) H and if the acceleration due to gravity in the area is G, then the potential energy P.E. of the body is given as
P.E. = M*G*H
Note: Unless specified differently in a numerical problem, G is always taken as 9.8m/s2
Units of Potential Energy:
The Unit of Potential Energy is same as that of Energy. In the S.I. unit system it is Joules and Newton-meter
Forms of potential energy:
There are many different forms of Potential Energy and each has its own formula for calculation, which we shall not discuss here. Some of these forms are:
Gravitational Potential Energy
Elastic Potential Energy
Electrodynamic Potential Energy
Electrostatic Potential Energy
Nuclear Potential Energy
All these forms have their individual uses, units and formulas.
Is this topic Rotational Kinetic Energy Formula hard for you? Watch out for my coming posts.
Potential Energy VS Kinetic Energy
Potential Energy is often confused with Kinetic Energy. There is a very elementary difference between these two expressions.
The Potential Energy refers to the energy possessed by a body at rest while Kinetic Energy refers to the energy possessed by a body in motion (i.e. the velocity of the body is taken into consideration).

General Electric Safety
Introduction to electrical safety pictures:
Electricity is the very useful form of energy in our daily life. Now at that time we cannot imagine the life without electricity. But, without proper precautions the electricity may be very harmful even it causes death also. To avoid the accidents from the electricity first make the two important safety features of the electricity. These two safety features are earthing and fuse.
Having problem with what is conservation of energy keep reading my upcoming posts, i will try to help you.
Earthing the electrical safety pictures:
Earthing is a process, which is used as the safety device for the user of electricity. In our main supply form the electrical pole there are three wires. These three wires are live wire, neutral wire and the earth wire. The other end of the earth wire is connected to the big metal plate and deep buried inside the earth. Most of the electrical appliances in our house are fitted with the three wires out of which one is the earth wire. The earth wire is connected to the metallic body of the electrical appliances with the help of a wire made by the lead. So connecting the metallic body of the electrical appliances by the earth is called earthing. The earthing of the electrical appliance is used to protect the user form the electrical shock.
Looking out for more help on Wavelength Formula in physics by visiting listed websites.
Fuse the electrical safety pictures:
An electrical fuse is a safety device to protect the electrical circuit form the overloading. A fuse is a thin piece of a wire made by the material having low melting point and high resistance. The fuse wire worked on the heating effect of the electric current. The fuse wire is made by the tin and copper alloy. A fuse is always connected in the live wire. As the large amount of the electric current pass through the circuit, the fuse wire gets heated according to the Joule’s heating effect of the electric current. Because the fuse wire has low melting point so it melts as the current is high and the circuit is incomplete so the flow of current restrict in the circuit and the appliance is safe now. We have to use a fuse wire of proper ratings. A thick wire has high rating.

Definition of Confined Space
Introduction to a confined space:
The term confined space is used in reference to a labor safety area. This is a space which is confined, and fact that it is confined makes it a dangerous place. A confined space is an enclosed space with limited access. This may or may not contain hazardous material.I like to share this Equation for Torque with you all through my article.
Definition of confined space
A confined space is an area that is enclosed and has limited access. This kind of space can be dangerous to people. Generally in industries certain variety of areas and spaces which are enclosed and have limited access are labeled confined spaces and there are certain rules and regulations to ensure safety and security of personnel operating in confined spaces.
By definition a confined space has restricted means of entry and exit, is not designed for continuous occupancy and is large enough for a person to perform tasks.
Some examples for confined spaces are a utility tunnel, inside of a fluid storage tank, inside of a boiler, inside of a septic tank, a underground electric vault etc.
Understanding Power Equation is always challenging for me but thanks to all science help websites to help me out.
Variation on definition of confined space
The definitions of confined space vary from one industry to another. As per OSHA, occupational safety and health administration, some of the confined spaces require permit to be used. some of the characteristics of confined spaces that require permit are the ones that contain hazardous atmosphere, the spaces where the material inside may engulf the person and cause suffocation or other physical discomfort, the way the space is constructed has a possibility of trapping the person or any other space that contains serious safety or health hazards.
There are several regulations that govern the existence, maintenance and usage of such confined spaces in most industries. The confined spaces are defined for most industries and there are industry specific regulations to govern the administration of such spaces. These spaces are primarily not built for being a workplace.
Conclusion for confined space
Confined space is a space that has limited entry and exit, that may contain hazardous material that may engulf and trap a person. These spaces are governed by industry specific confined space regulations. The definitions of confined space vary from one industry to another.

Science Homework Help of Magnetism
Introduction on science homework help of magnetism:
Magnetism is the property by the virtue of which any substance gets attracted to iron, both ferrous or ferrite but not its alloys. Every magnet has a dipole, i.e. north and south poles. In fact our earth is a big magnet and tends to magnetize anything which lies in it for a considerable amount of time and hence the discovery of magnet. Magnet when initially discovered was known as lodestone, and it helped in guiding to proper direction.
Understanding How are Electricity and Magnetism Related is always challenging for me but thanks to all science help websites to help me out.
Magnetic lines of force of magnetism:
Magnets can be both natural magnets as the lodestone or artificially prepared as the electromagnets. Magnets always give rise to magnetic lines of forces i.e. outward originating from the North Pole and terminating in the South Pole, and an inward movement from the South Pole to the North Pole. This can be successfully depicted by the iron fillings method and the compass needle method.
Demagnetism homework help:
Even natural magnets can be demagnetized very easily and hence proper precaution should be taken in tackling with the same. Some of this methods which can lead to demagnetization are:
By rough handling – Repeatedly dropped or hammered
By heating – Heating to develop magnetic agitation and hence loss in magnetism
Electrical method – Wounding a coil around it, and alternating current is passed
By Induction – Like poles of another magnet are placed in front of each other.
Self demagnetization – Loosing magnetism of its own accord
Is this topic Free Fall Equation hard for you? Watch out for my coming posts.
Methods of Magnetization:
On can magnetize an iron bar, to behave as a magnet in the following manner:\
Single touch method – Rubbing a magnet over a steel bar
Double touch method – Rubbing 2 magnets over a steel bar, mounted on 2 other magnets. A cork is kept to separate the rubbing magnets.
Divided touch – Same as double touch but the cork is absent.
Electrical – Current is passed through them in N-S direction
Induction method – Iron bar is brought near a magnet
Thus we see the how magnets can be beneficial in our lives.

Features of Platyhelminthes
Introduction to Features of platyhelminthes
Platyhelminthes are commonly called as Flatworms. The word Platyhelminthes is derived from the Greek word platy for flat and helminthes for worms. Platyhelminthes belongs to an ancient phylum, nothing much is known about their evolutionary history because of their very soft bodies which do not preserve well as fossils. Scientists believe that they might have evolved around 550 million years ago. Since the Platyhelminthes look like worms like creatures they are called with different names such as Flatworm, Tapeworm, Fluke and Planarian.
Is this topic Units of Acceleration hard for you? Watch out for my coming posts.
The Platyhelminthes are divided into groups
Turbellaria
Monogenea
Trematoda
Cestoda
Turbellaria are mostly free-living and a few of them are parasitic. They are found in fresh water, oceans and in moist terrestrial habitats.
Monogenea are commonly known as flukes. The Monogenea are mostly external parasites of fish and have a simple life-cycle involving only one host.
Trematoda are commonly known as flukes. Trematoda are mainly endoparasitic in nature and have a life-cycle involving more than one host which is more complicated.
The Cestoda are commonly known as tapeworms, they are intestinal parasites in vertebrates.
Let us see the important Features of platyhelminthes.
Understanding Free Fall Equation is always challenging for me but thanks to all science help websites to help me out.
Important Features of platyhelminthes:
Bilaterally symmetrical and triploblastic body (composed of three fundamental cell layers) Are the important features of Platyhelminthes.
The body is usually flattened dorsoventrally and No true segmentation is present.
The Epidermis is soft and ciliated, or covered with cuticule and it has external suckers or hooks, or both for connection to host.
Absence of the body cavity except the gut is one of the important features of platyhelminthes.
It has a Digestive system which is incomplete i.e. it has a mouth but no anus and usually much branched.
Another important features Platyhelminthes is it has a Protonephridial excretory organ instead of an anus.
Absence of skeletal, circulatory or respiratory system is one of the features of platyhelminthes
It has normally a nervous system of longitudinal fibers with transverse commissures.
As they are hermaphrodites the reproduction is mostly sexual and the Fertilization occurs internally.

Sodium Chloride From Water
Introduction to Sodium Chloride from water:
Sodium Chloride is an ionic compound with its IUPAC name as Sodium Chloride and
Common names as common salt, saltex, halite, table salt, rock salt, saline, hypo saline, sodium mono chloride, sodium chloric.
It is represented by NaCl. It is major ingredient in edible salt, and is commonly used for adding flavor to the complement food and also used food preservatives.
Sodium Chloride is a very good conductor of heat and electricity. Also, because of the ionic bonds formed between sodium and chlorine, sodium chloride dissolves in water.
Please express your views of this topic Specific Heat of Ethanol by commenting on blog.
Methods to separate sodium chloride from water:
There are various methods to separate sodium chloride from water. Some of them are as follows:-
1.Evaporation
Evaporation is a process of continuous heating of any liquid till that point when all the liquid gets evaporated. It is considered as the natural removal of water from the solution at relatively low temperature. So, for separating sodium chloride from water, the process of evaporation is used. So, in it when the water evaporates away, and the salt remains in the container. Then, it is separated away from the water. But, it's a slow method of separation of sodium chloride from water.
2.Distillation
Other method to separate sodium chloride from water is distillation. Distillation means to boil the water out of the solution as steam. By doing so, the salt will remain in the container (distillation flask) while the water can be collected in another flask. The steam can be condensed if required to produce pure water(known as desalination).Distillation is used commercially to produce large quantities of pure water from sea water for industrial and domestic use in areas where natural fresh water is not readily available. As in desert regions etc. This however is done as a continuous process and the sea water is flowing through the distillation unit leaving the outlet flow with more salt in it as some of the water is distilled off. The process is also carried out under high vacuum to decrease the boiling temperature of the sea water to about 65°C, thereby reducing the heat input.).

Conclusion for separation of sodium chloride from water:
From the above we can conclude that sodium chloride can be separated from water by two methods: distillation and evaporation.

Soil Moisture Percentage
Introduction to Measuring Soil Moisture Percentage
Soil Moisture is the amount of moisture present in the soil. It can be estimated by feel and the appearance of the soil. To estimate soil moisture, Tensiometers or resistance blocks may be used. For the measurement of moisture, we check it in at least one location for each area of the field because it differs from other areas in soil slope and texture.
Please express your views of this topic Digital Hydrometer by commenting on blog.
Methods for Measuring Soil Moisture Percentage
There are mainly three methods for measuring soil moisture percentage.
Soil Survey Standard Test Method: This method is based on the removal of soil moisture by oven drying a soil sample until the weight remains constant.
Time-Domain Reflectometer: This method involves the propagation of electromagnetic waves or signals. This method is independent of soil texture, temperature and salinity. It is possible to perform long term in situ measurements. But the disadvantage of this method is that it is very costly.
Gravimetric method: This method involves removal of the soil sample from the field, and determination of the mass of water contained in the soil relative to the mass of dry soil. This method ensures accurate measurements but it has lot of disadvantages. This is time consuming method, inapplicable to automatic control.
Soil Moisture Percentage : Equipment Used
Tape measures, permanent marking pen, soil auger instruments, box of gallon sized Zip-lock plastic bags, field note book, access to a soil lab etc.
For fine grained soils, medium grained and course grained soils, procedures are different.
Is this topic Angular Speed Formula hard for you? Watch out for my coming posts.
Soil Moisture Percentage :Calculation
In general, Soil moisture is reported as percent moisture, where
Moisture content (%) = ((wet weight – dry weight)/(wet weight)) * 100
We calculate the moisture content of the soil as a percentage of the dry soil weight.
MC% = (W2 – W3)/ (W3-W1) * 100
Where:
W1 = Weight of Tin (g)
W2 = Weight of moist soil + tin (g)
W3 = Weight of dried soil + tin (g)
Where chemical analysis are performed on moist samples because it is convenient to correct the results to an oven-dry basis by use of appropriate Moisture Factor (MF) which is calculated as follows:
MF = (W2 –W1)/(W3 – W1)
Or MF = 1 + (MC/100)
Here MC = Moisture Content

What is a Pure Solvent
Introduction to what is a pure solvent:
Solvent may be defined as the ability of a substance to dissolve another substance within and determined by their molecular structure compatibility. Solvents are usually organic and inorganic solvents.
Please express your views of this topic finding density by commenting on blog.
Water as pure solvent:
Water, apart from being an ideal solvent because of its intermolecular structure, its compactly packed structures facilitates easy movement as in the case of osmosis, movement from an area of low concentration to an area of higher concentration. Water is usually appearing in its pure state, almost a pure solvent, unless distillated. For instance, dissolving of sodium chloride or potassium nitrate in pure water, a pure solvent, lowers the freezing point irrespective of the salt added. The freezing point remains the same upon addition of either of the solutes provided in equal molar amounts.
Molecules of pure aromatic organic solvents have a structure of benzene ring in them. Few examples of pure aromatic solvents are benzene, xylene and toluene. Pure aromatic organic solvents are usually used in the degreasing, used as thinners, for paint manufacturing, printing inks, agricultural chemicals and insecticides.
Other properties of pure solvent
The boiling point of a pure solvent is lower than the boiling point of the solution. Hence, the use of a solution rather than the pure solvent as in antifreeze helps in keeping the mixture from boiling in a hot automobile engine. The solution’s freezing point is decreased by the presence of a solute relative to that of a pure solvent. Taking an example of pure water that freezes at 0oC and when ten grams of sodium chloride is dissolved, the freezing point of the resulting salt solution is less by 5.9oC. Vapour pressure of a solvent as stated by the Raoult’s law is equal to the vapour pressure of a solution of a non-volatile solute divided by its mole fraction.

Conclusion on what is a pure solvent:
A pure solvent, like water, which is a universal solvent due to the intermolecular structures, is widely used. Organic pure solvents, which are aromatic like benzene, toluene, and xylene, have a benzene ring structure. The colligative properties of solutions differ from pure solvents due to its property of depending upon the number of solutes present in a solution, irrespective of the solutes present.

Conclusion on what is a pure solvent:
A pure solvent, like water, which is a universal solvent due to the intermolecular structures, is widely used. Organic pure solvents, which are aromatic like benzene, toluene, and xylene, have a benzene ring structure. The colligative properties of solutions differ from pure solvents due to its property of depending upon the number of solutes present in a solution, irrespective of the solutes present.
What is Human Resources Manager
Introduction on What is human resource manager:
Human resource manager is generally involved in the task of recruitment, selection, direction and management of the people working in an organization. Sometimes line managers also perform the work of a human resource manager. Human resource manager’s functions are to deal with the issues relating to compensation, benefits, hiring, performance management, development of an organization, safety of employees, wellness of employees, and other new and important functions included are increasing employees motivation, managing proper communication, administration of employees and providing training to newly recruited. I like to share this density experiment with you all through my article.
Responsibilities of a human resource manager:
Responsibilities of a human resource manager differ based on organization to organization. In large organizations one can see separate human resource departments which directly reports to the management. There are many specialized human resource staffs behind the head human resource manager like the training manager, the compensation manager and the recruiting manager. In small organizations the work of a human resource manager is more of a personnel management manager. In other terms human resource management has largely replaced personnel management.
A human resource manager is advocate to both the sides; the firm and its employees. It is the gap between the two parties and has to serve the interest of both the parties. The human resource manager has to make both the ends meet. As the firm and its employees have different motives and there are clashes in their thoughts so a human resource manager has to balance the needs of the two. So the responsibility of recruiting, hiring, training, coaching, Performance management, managing salary and benefits, incentives, employee relations, team building, leadership and overall organization development have to be carried out with due care by a human resource manager.
Understanding fahrenheit to kelvin formula is always challenging for me but thanks to all science help websites to help me out.
Role of human resource manager:
Advocate to the employees and provide assistance programs to employees. A Human resource manager should be trust worthy.
Bringing efficiency and effectiveness in an organization by successfully implementing various strategies and bringing change to an organization.

What Compounds Dissolve in Water
Introduction to the compounds that dissolve in water:
When the table salt and sugar added in water they dissolve as they are soluble in water. But when petroleum is added in to water it does not dissolves same with the sand it does not dissolves as both are insoluble in water. The solubility of different compound helps us to predict what compound dissolves in water. The complete information of what compound dissolves in water helps us to prepare the stock solution of compounds for their analysis. Please express your views of this topic Energy Types by commenting on blog.
Solubility compounds dissolve in water:
Solubility is main criteria that give us information the compound dissolves in water. Solubility is ability of solid, liquid and gases to dissolves in to the liquid to give homogeneous solution. The solid, liquid, gases that dissolve in to the liquid are known as solute while the liquid that dissolves the solute is known as the solvent. The value of solubility is expressed in g/ml. The value of solubility of various compounds in water gives an idea that what compound dissolves in water in what amount. The solubility of compound in water can be affected by temperature and pressure, as the increases in temperature increase the solubility of compounds while reduction in the temperature decreases their solubility. Same with the pressure, pressure increment increase the compound solubility in the water.

Ionic compounds and water solubility
When the ionic compounds are dissolves in the water they will solublizes like sodium chloride, magnesium chloride. But when the organic covalent compounds dissolves in water they will not solublizes like methane, carbon tetrachloride. Water solublizes any compound if it able to break the interionic interaction of the compounds, therefore the answer of what compound dissolves in water is that only that compound dissolves in water is that compounds for which water is able to break down their ionic interaction. There are also two rules to find out what compounds soluble in water.
The solubility of compounds in water is high if force of attraction in between water molecules and oppositely charged ions are high as compared to the force of attraction between negatively charged ions.
The solubility of compounds in water is low if force of attraction in between water molecules and oppositely charged ions are low as compared to the force of attraction between negatively charged ions.

Adding Acid to Water
Introduction on adding acid to water:
Acid: The sour taste of lemon is due to the presence of an acid in it. The acid present in lemon which gives it a sour taste is citric acid. Acids are those chemical substances which have a sour taste. They change the color of blue litmus to red. Some of the common fruits such as raw mango, raw grapes, lemon, orange and tamarind etc are sour in taste due to the presence of acids in them. Soured milk also contains acid in it.
Please express your views of this topic Physics Equations of Motion by commenting on blog.
Concentrated acid and dilution
A concentrated acid is one which contains the minimum possible amount of water in it. The concentration of an acid is decreased by adding more water in it. When water is added to a concentrated acid, then a dilute acid is formed. Thus, a dilute acid is one which contains much more of water in it. So, a concentrated acid can be diluted by adding more water into it.
The term dilution stands for making the water more in an concentrated acid. The process of mixing the concentrated acid with water is highly exothermic, i.e. a lot of heat energy is produced. There uttermost care should be taken while diluting an concentrated acid, they should be mixed with each gradually with constant stirring. However, in no case, the water should be directly added into acid.
Is this topic dot product problems hard for you? Watch out for my coming posts.
Impact in the observer
When we add a concentrated acid into water for preparing a dilute acid, then the heat evolved is gradual and it can be absorbed by the water being added to the concentrated acid. So, As a result there is no liberation of energy, which can cause harmful impact on the observer.
On the other hand, if water is added to directly with concentrated acid to dilute it, then the amount of heat energy evolved is immense. Due to large heat energy , the water is changed into steam, that can cause the splashing of water-acid mixture and cause severe burns. Even the glass container may break due to excessive heating.
Therefore, one has to be very alert while adding an acid to water. As, it could be an extremely dangerous affair.

Thermal Energy Com
Introduction:
Thermal energy storage may be refer to the number of technologies that Store energy in a thermal reservoir for later reuse. They can be employed to the balance energy of demand between the day time and night time. The thermal reservoir to be maintained at the temperature of above (hotter) or below (colder) than that of the ambient environment. The principal of the application today is the production of ice chilled water, or eutectic solution at night, which is then used to cool environments during the day.
I like to share this Activation Energy Equation with you all through my article.
Economics
The most widely to used form of this technology is in large building or campus-wide air condition or chilled water systems. Air conditioning systems,is especially in the commercial buildings, are the most significant contributors to the peak electrical loads seen on hot summer days. In this application is the relatively standard chiller is run at night to produce a pile of ice. Water is the circulated through the pile during the day to produce chilled water that would normally be the daytime output of the chillers.
A partial storage to the system minimizes capital investment by running the chillers 24 hours a day. At night of the produce ice for storage, and during the day they chill water for the air conditioning system, their production augmented by water circulating through the melting ice. Such a system is usually runs in ice-making mode for 16 to 18 hours a day.

Facts About Thermal Energy
Interesting facts about Thermal Energy:
Thermal energy is brought forth and appraised by heat energy of whatever form. It is induced by the expanded process or speed of atoms in a content, which successively drives temperature to climb up consequently. Earth contains many natural sources of thermal energy on it which results in the availability of best optional energy to humans. I like to share this All Types of Energy with you all through my article.
The laws of thermodynamics explicate that energy in the form of heat can be commuted from one object to another. For example, putting fire under a vessel of wax will cause the wax to melt up as a result of the expanded atom drift. Here the process that thermal energy of the fire is transmitted to the wax upto some extent.
The laws of thermodynamics has granted mankind to tackle natural sources of heat to produce thermal energy. The sun, ocean, and geothermic sources such as volcanoes, can all be called as the most beneficial generators of thermal energy. Solar thermal power is one among the best form of thermal energy available today.
Disadvantage
But the biggest disadvantage of this method is that we need to have sun visible for more time to collect the power. However the technology has improved so much that many devices has come up for the sake of absorbing and storign the solar energy and to use it whenever we require.

Utilization of Solar Energy
Some of the contemporary devices used by solar energy
Watches, cooking tools, radios, lanterns, GPS systems, heaters, traffic signals.
These are some of the devices used in modern day to absorb the energy from sun and to utilize it as an alternate energy. Thermal energy is an wonderful source of energy. If we people learn that how to utilize the natural resources effectively by storing, maintaining and to commute it properly, we can majorly reduce our dependancy on artificial forms of energy.

Diffraction wavelength
Let us start with what is diffraction of light first and try to answer it. It is basically the bending of the light rays when it passes from a small slit or it is the phenomenon by which the ray of light changes its path or direction slightly when it encounters an obstacle. Please express your views of this topic Wavelength Spectrum by commenting on blog.
It is visible in daily life when we have a hole in the wall and the sun rays are coming through it. Note that you can see the light rays spread out from the hole and form a cone like structure of the light.
Diffraction of light waves can be seen more profoundly when the wavelength of the light rays is of order of the size of the object that is acting like the obstacle. If the wavelength does not match then it would be very difficult to observe these phenomena although it will occur. A diffracted wave will hence almost be of same wavelength. It is basically caused due to the formation of maxima and minima.
In fraunhofer diffraction we have the formation of fringes and alternate black and white stripes which is evident of the diffraction Phenomenon. Basically what happens is that each particle in the light wave is in turn the source of light and hence secondary waves are generated at all the points. Now the intensity of these waves ( secondary ) can be different and at any point the intensity observed will be the sum or aggregation of all the intensities from all the sources for that particular point. This may sometime lead to a minima and sometime lead to a maxima.
Having problem with Work Problems keep reading my upcoming posts, i will try to help you.
At point of minima, when the resultant intensity is zero we get dark areas. In areas of maxima where the resultant intensity is a constant value we get maxima and hence the fringes which are not dark. In this way a pattern of alternate fringes ( dark and light ) is formed which is called the pattern formation in diffraction.
There are various equations and formulas considering the intensities at any point. There are diffraction grating equation derivation topics that will lead to a clear understanding of the phenomenon. There are many types of this like circular aperture form along with single slit and dual slit forms.
For each one of them we have specific path difference formula.
For example d sin theta = n v
Here theta is the angle of incidence.
V is the wavelength of the light.
N is a constant.

Photometry Tutorial
This Photometry Tutorial is aimed at giving you a brief overview of photometry. Let us start with the basic definition of photometry. In simple words it is the science of measurement of visible light. When I say visible light I mean the light in the wavelength range of 400 to 700 nm. I like to share this Definition of Atomic Radius with you all through my article.
About what is Photometry, there is a much simpler answer. The measurement of the light is done in terms of the intensity in which it is received or perceived by human eyes. As we know that the human eye does not perceive each and every wavelength of light equally. It has different perception for different wavelength. So we have a factor in this topic which accounts for the level of perception of human eye, different for different wavelengths. In this way the required measurement is done for each and every wavelength.
The SI units for this are Candella or lumens etc. There are various instruments called photometers that are used for the measurement purposes. They can be used for lights with different wavelengths and different intensities and flux.
Aperture format is another application of normal photometric techniques. When we use a CCD camera various techniques can be applied to measure the light. One such technique is aperture photometry. In this the rays of light coming from the object from different points will be added while those coming from the sky will be averaged out and subtracted. In this way we can clearly measure the light from the object.
The technique used in Differential format is entirely different. The light coming from the object over time is measured. It will be then averaged to form a light curve. In some cases all the observation are just mapped to form the curve.
Having problem with what is the formula for speed keep reading my upcoming posts, i will try to help you.
The changes measured are over a significantly long interval which can range from days to months. High precision can be obtained when such a technique is used which is not the case if we use absolute form of this.
It should be noted that the light coming from the atmosphere can also vary over time while using the differential techniques. This is also taken into account and averaged out accordingly.
These are covered under the same light curve in most the time, but sometimes it can have individual curves as well.
It has many uses. It is also used in chemistry for measuring the light coming from the chemical solutions etc.

Water Environmental Issue
Introduction to water environmental issue:
Water environmental issue determines the pollution occurred in the environment. The pollution in the environment causes due to the non dissolved solvents. The impurities in the water are dissolved in the water and some of the solvent are suspended in the water. The impurities like clay particles, micro organisms and various algae and fungi are found in the water.
I like to share this what is the formula for speed with you all through my article.
Water environmental issue:
The water environment contains the biotic and also abiotic components. The water environmental issues contain the following factors.
1) Effects on the aquatic ecosystem
2) Eutrophication
3) Biological magnification
Effect on aquatic ecosystem:
The inorganic and organic substances enters into the aquatic ecosystems reduce the oxygen content.
Sufficient amount of oxygen is required for aquatic organisms.
Aquatic system is affected due to environmental issues.
More oxygen is used up in decomposition of organic waste.
The measurement of the amount of oxygen required for decomposition of biodegradable substances.
The water includes the biodegradable and also non biodegradable pollutants.
Thus, the pollution of water increases the amount of dissolved oxygen decreases.
Moreover some toxic pollutants directly kill some organisms.
Understanding Electric Circuit Simulator is always challenging for me but thanks to all science help websites to help me out.
Eutrophication:
Eutrophication means an easy availability of nutrients in an aquatic habitat.
The habitat in the ecosystem is affected due to the water environmental issue.
The inorganic and organic substances are added to water, the availability of nutrients increases.
When sewage, fertilizers and detergents are added to water, the growth of the micro organisms and aquatic vegetation is stimulated.
Algae and blue green- algae are completely spread over the entire water surface and generate a foul smell and toxic taste- spoiling substances.
A large number of fishes are died in some times.
With the passage of time, the water reservoirs become shallow and ultimately get filled up.
In this way the lifespan of the anthropogenic water reservoirs is limited.

Global Warming and Climate Change
A Detailed Study on Global Warming and Climate Changes:
Yes the heat is finally on. Global warming and Climate Change are no longer terms in scientific dissertations and schoolbooks, they have actually begun impacting our daily lives striking close to home. Years of neglect and complete disregard for the environment are now making its presence felt. The primary reason for this has been the relentless progress of mankind at the expense of nature and other species inhabiting the planet. Till a few centuries ago, all was well, with peaceful cohabitation of all. With the advent of engines, automobiles, industrialization …all of this has led to unprecedented levels of pollution in the atmosphere.
I like to share this how to conserve energy with you all through my article.
Relation between Global Warming and Climatic Changes:
The accumulation of toxic gases in the atmosphere, as a result of automobile and factory emissions especially over the last few decades, has led to an accelerated rate of environmental degeneration. The delicate balance of ecology which meant that every single green leaf and tiny insect had a role to play, has been totally thrown into disarray, inundated by effluents and emissions, sometimes teetering on the brink of obliteration. This total disruption of nature’s cycles has led to a corresponding change in climate as well. The toxic gases in the atmosphere trap heat, which leads to rising of temperature across land and oceans which we call global warming. This in turn leads to disruption in the timely onset of seasonal rainfall and expected weather changes. Thus winters are either prolonged or excessively cold or cut abruptly short without any discernible drop in temperature. Summers can be terribly warm and enervating with unnatural untimely storms that suddenly blow over creating destruction in its wake. Tidal waves, unprecedented torrential rainfall, heavy blizzards, dust storms, hurricanes, twisters....it seems as though Nature has unleashed her fury on a callous mankind who is hell bent on desecration.
Having problem with What is Average Atomic Mass keep reading my upcoming posts, i will try to help you.
Both global warming and climate change are interlinked. Each impacts the other and is at once both a cause and an effect. But the root cause is the mindless destruction of the environment by unplanned human activity. No one had the foresight to realize that the great advances made in science and technology needed to have a planned execution with a system of checks and balances incorporated so as not to disturb the natural world. In the clash between Nature and Science, Nature has borne most of the brunt of population explosion, human activity and advancement. Global warming and climate change are a direct fallout of this clash. Drastic measures have to be taken to save the planet as time is running out.
Yes the heat is finally on. Global warming and Climate Change are no longer terms in scientific dissertations and schoolbooks, they have actually begun impacting our daily lives striking close to home. Years of neglect and complete disregard for the environment are now making its presence felt. The primary reason for this has been the relentless progress of mankind at the expense of nature and other species inhabiting the planet. Till a few centuries ago, all was well, with peaceful cohabitation of all. With the advent of engines, automobiles, industrialization …all of this has led to unprecedented levels of pollution in the atmosphere.
I like to share this how to conserve energy with you all through my article.
Relation between Global Warming and Climatic Changes:
The accumulation of toxic gases in the atmosphere, as a result of automobile and factory emissions especially over the last few decades, has led to an accelerated rate of environmental degeneration. The delicate balance of ecology which meant that every single green leaf and tiny insect had a role to play, has been totally thrown into disarray, inundated by effluents and emissions, sometimes teetering on the brink of obliteration. This total disruption of nature’s cycles has led to a corresponding change in climate as well. The toxic gases in the atmosphere trap heat, which leads to rising of temperature across land and oceans which we call global warming. This in turn leads to disruption in the timely onset of seasonal rainfall and expected weather changes. Thus winters are either prolonged or excessively cold or cut abruptly short without any discernible drop in temperature. Summers can be terribly warm and enervating with unnatural untimely storms that suddenly blow over creating destruction in its wake. Tidal waves, unprecedented torrential rainfall, heavy blizzards, dust storms, hurricanes, twisters....it seems as though Nature has unleashed her fury on a callous mankind who is hell bent on desecration.

Sodium Formula Weight
Introduction to sodium formula weight:
The sum of the atomic weights for all the atoms present is the formula weight. The molecular weight is referred to as the formula weight, where the individual units of a number of covalent compounds are molecules. The formula weight of sodium remains usually equivalent to the atomic weight in the case of sodium, because sodium is a diatomic molecule and not a compound. The formula weight of sodium is hence equivalent to the molar mass, previously termed as formula weight, the relative molar mass.
Formula weight of sodium
is a quantity that is computed by the multiplication of atomic weight of each element by a number of atoms in a chemical formula of that element that is present in the formula and then sum of all the products together. Formula weights help in the determination of relative weight of the reagents and the products of a chemical reaction. Formula weight calculated will be equivalent to the molecular weight, when the molar mass calculation formula is the molecular formula. Formula weight is the weight of all the atoms in a given formula in atomic mass units. To simplify formula weight of a substance is its gram molecular weight.
Formula weight of sodium formula weight:
Sodium has a molar mass, which is the average molecular weight based on isotropically weighted averages of 22.989770 g/mol. Sodium has an atomic number of eleven and the molar mass is calculated on the basis of the atomic weight. In the case of stoichiometric calculations, determination of molar mass is usually practised that determines standard atomic weight. The formula weight of a sodium molecule can be determined by the atomic weight of the sodium, since sodium molecule is not a compound, but is an element with two sodium atoms bonded together.
Conclusion on sodium formula weight:
Sodium, which is a diatomic molecule, is commonly available in nature in the form of its compounds, a diatomic molecule of sodium has a formula weight of 22.98.770, which is equivalent to the atomic weight in case of sodium, since it is an element, and a molecule of sodium has two sodium atoms. Formula weights of various compounds of sodium may be calculated by the addition of the individual atomic weights of the different atoms present.

Simple Energy Experiments
Introduction to simple energy experiments:
The energy means the capacity to do work. The energy of every object is depends on the work done by that object. If more is the work done by the object then more is the energy in the object and vice versa. There are several types of energy. The work and the energy are the equivalent form of each other so that the unit of energy and the work is same. The energy is a scalar quantity. There are so many experiments based on the energy. Here we discuss some of the simple experiments based on the energy.
Simple energy experiments:
Here first we discuss a water energy experiment. This is one of the simplest experiment based on the water energy, it also gives an idea of power of sun and harvesting by the solar energy in our daily life. The main materials required are large bowl from the kitchen, any clean plastic sheet, a drinking glass, some amount of table salt, any food colour, ordinary tap water and a small stone. Mix the food colour and the table salt in the water. Now place the glass in the centre of the large bowl. Now cover the bowl containing the glass with the plastic sheet. The plastic sheet is little loose on the mouth of the bowl. Now place the small stone at the centre of the plastic sheet so that the stone dip in the plastic sheet and it is exactly above the glass. Now place the whole set up in the sun light.
Here we observed that the plastic sheet and the salty coloured water trap the heat energy from the sun so that the temperature of the bowl containing water increases. Now the result is the evaporation of water from the salty and coloured solution. The water vapour reaches the plastic sheet and then condensed at just below the stone and runs down in the glass. This is the water free from the colour and the salt.
Concluding simple energy experiments:
This shows that how the solar energy works to purify the water and how the plants get the water for the harvesting. Because the solar energy is the renewable source of energy and it is free of cost so we use this method on the large scale to purify the water.

Protect Wood From Water
Introduction to protect wood from water:
Mostly at home the decorative articles and things of daily use are made of wood. Things like your simple chairs to expensive sofa, from basic doors to elaborate and antic cupboard.These things bring about a warmth and serenity in the house but can be the most important things for usage saving us from the official or hospital look in our house.at times it not easy to save and restore the wood items from unwanted elements.
Some varieties of wood have a natural ability to deter decay or rot . For other few we can coat them with preservatives to make them more durable. Redwood and Cedar are some durable species, commonly used for wood exposed outdoors, such as siding, shakes and shingles, decks, furniture, and fences. These types of wood have natural chemicals which impart durability.The natural chemicals are present in the heartwood of the tree.

Protection of wood from water
The materials that made from durable wood and are naturally resistant to decay are the best option for a long run and households . However there are many softwood with are great to make articles from but are not that durable .Durability and resistance can be induced by usage of synthetic factory made resistant.
These days there are many products aimed for different kinds of protection from UV to moisture , to decay and infestation. These not only protect the wood article from attacks but also preserves it for future and increases the life .
Keep the wood clean and make sure it does not go under any unnecessary strains.If it is a working surface usage of acrylic top is always a good idea .It should be kept in m in that treatment done on the wood is not forever so it should be repeated in the stipulated time .
Is this topic What is Average Atomic Mass hard for you? Watch out for my coming posts.
Advantages of Water-Repellent Preservatives
Retard decay in above-ground applications
Decrease raised grain, checking, warping, and splitting
Inhibit mildew growth on both painted and unpainted wood
Retard iron stain
Stop extractive bleed
Improve paint adhesion
Prevention steps at home
As it is said prevention is better than cure, any household having a great number of wooden items should keep a few things in mind.
Always keep a check on the leaks and cracks in your home; it is the place from where moisture can seep into the wood.
Windows, doors and awning are the most exposed area made of wood – they should be painted over with good quality weather resistant paint and polish .The doors and windows should be checked for swellings and cracks. Swelling and cracks is sign that the moisture has been absorbed by the wood and can cause damage to them. It may even cause breakage and make it suitable for termite infestation.
Attic and Plumbing vents can form leakage and water logging. The ever required indoor plumbing can also cause the mater water leakage and damping in a home. They should be checked regularly for blocking, leakage and breakage.
Keep check on the humidity level inside your home . Also rust formation also should be noted .This moisture can slowly get absorbed into the wood and decrease the life span of the artifact.

What is Global Management
Global management is the ability of a company to function from any part of its country, and have access throughout the world, through the establishment of branches in those other places. The world has been shrunk with the innovation of telecommunication. Likewise, global management has become more suitable for today’s fast paced life.
Introduction on What is Global Management
Global management deals with handling of people who belong to different culture, region and languages. Marketing strategies have to modified based on the above. Global management techniques help in developing such skills.
Outsourcing is a kind of global management that has been taking place for a long time. People in different parts of the world, are employed to do a particular work that belongs to some other region of the world. To efficiently handle such work people must be aware of the culture, language, and life of others. Global management plays a vital role in preparing employees for such situation.
Please express your views of this topic formula of pressure by commenting on blog.
Role of Multinational Companies in Global management:
Multinational companies:- The name itself suggests that the companies are run in more than one country. These are some of the fine examples to talk about global management.
Multinational companies have branches in several countries and they promise products and goods as equal as the ones manufactured in their own country. To ensure this, they have to train their employees about the global management so that they meet the required
quality in the job specified. For example, KFC [Kentucky fried chicken] has its branches in so many countries, and they provide the similar quality and services in all those countries. Those who wish to work for these should be able to learn and know the standards of the company in its original place. Global management helps in teaching these standards.

Global management and job opportunity
In conclusion, global management has become the need of the hour as it caters to the needs of the people of the world. One can undergo training and become better global managers thereby increasing their scope of getting a right job in the global market.
Since the market is very large, it has the potential to provide work to large number of people, by governing them from their own country.

What is Runoff Pollution
What is runoff pollution?
Runoff pollution is nonpoint source of pollution in our environment. It basically is water from rain, polluted by cigarette butts, used oil, paint, fertilizers and pesticides, dirt and dust, trash, automotive fluids, rubber and metal deposits from tire wear, antifreeze and engine oil that has dropped onto the pavement, pesticides and fertilizers, and discarded cups, plastic bags, lawn and garden clippings and pet waste. Rainwater or melting snow washes off roads, bridges, parking lots, rooftops, and other impermeable surfaces and more prone to pollutants of surroundings .
It directly flows into rivers and lakes. It is one of the main reasons for pollution of water bodies harming fish and aquatic habitats. It is totally different from Sanitary Sewer because it is not treated and filtered in wastewater treatment plant but goes directly into lakes, rivers and the ocean.
Having problem with Angular Acceleration Formula keep reading my upcoming posts, i will try to help you.
Reasons for Runoff Pollution:
There are many natural and artificial reasons of this kind of pollution. Among natural reasons Atmospheric deposition and hydro modification are main sources.
Natural erosion plays a vital role in causing runoff pollution but this process is a slow and gradual process while manmade causes are rapid and far more harmful. Natural erosion cause only soil sediment not metal and chemical particle sediment.
Deforestation leaves soil exposed and unprotected to be quickly washed away in the rain.
Heavy metal particles and pesticides along with soil are also transported by wind and water and deposited in beds of river. These particles cause harmful chemical balance of aquatic life by degrading the water quality. These agents are main contributors to runoff pollution. Runoff pollution reduces amount of oxygen into water. Again these heavy metal particles come from natural as well as human made situations. Their natural source is mineral rocks, salt, san and vegetation etc while they also come from vehicles exhaust, paint and rust. Metal particles are far more harmful than soil particles. They intoxicate the the aquatic life and potentially endanger aquatic life
Effects of Runoff Pollution
Effects of Runoff pollution are very harmful and not easily assessable.
Runoff pollution produces sediment because soil particles are eroded from the land surface and transported to water bodies. Soil particles settle out of the water in a lake, river and prevents sunlight from reaching aquatic plants and animals.
Runoff pollution makes river and ocean water unsafe for humans and wildlife as well. In some area, it becomes so serious that beaches have to be closed. The most harmful effect is contamination of drinking water. Runoff pollution directly goes into rivers, which are main sources of drinking water.
Fish stocks are also affected, many fishes die due to contamination of water bodies. It harms aquatic life by disturbing photosynthesis, respiration, growth, and reproduction.
Chemicals such as phosphates become more harmful for aquatic wildlife when it is added to dirt and oil particles. They cause algae production. Algae cause eutrophication of water bodies and reduce oxygen mixed in water while decaying process.
I like to share this Electric Field Formula with you all through my article.
Measure to be taken to control Runoff Pollution
Increasing awareness in common people.
Good maintenance of vehicles so that oil and engine fluids are not poured on roads and pavements and engine leaks is also repaired immediately.
Using approved motor oil.
Keeping weather forecast for rain in mind so that chemicals or fertilizer do not wash away with the rain.
