Introduction to voluntary muscle movement:
Muscle movements are primarily of two type’s i.e.
• Voluntary muscle movement
• Involuntary muscle movement
Voluntary muscles basically refer to those types of muscles, which respond to our will. These muscles act whenever we want them to act. Many examples can be moving of leg, winking of eyes etc.
Examples on voluntary muscle movement:
We can use our limbs both fore limbs i.e. hands and hind limbs i.e. legs as we want them to use. An example would make it lot clearer. Consider a sprinter who wishes to participate in a race. As soon as the pistol bangs, he should start sprinting in order to be part of the racing sport. Now here the sprinter is in command of his hind limbs i.e. the legs and the legs respond to his will. So we can see that voluntary muscles can be fully controlled by our wish. Another example can be of an archer who points an arrow at the bull’s eye. The banging of the revolver sends a message to his brain and he shoots the arrow at the bull’s eye. Here again we see that the fore limbs are in his full control.
voluntary muscle movement: conclusion:
Thus any action which stimulates our body parts to take action both aggressive and defensive is called as voluntary in nature, and the muscles detrimental in achieving the same are called voluntary muscles. This is in complete contrast to the involuntary muscles on which we have no command. Examples could be pumping of heart, the respiratory system. One can’t regulate the heart, or the respiration. These actions are said to be involuntary in nature. Basically one can say all the internal organs right from the flow of blood in our veins to the ultra filtration of blood in the kidney can be classified as involuntary, rest all the actions can be termed as voluntary in nature.

What Minerals are in Marble
Introduction on minerals in marble:
Marble is a type of rock widely used in buildings, monuments, and sculptures. The word marble is from a Greek word ‘marmaros’ which means shining stone. According to geologists, marble is a non-foliated, granular metamorphic rock. Marble is found in many countries, such as Belgium, France, Great Britain, Greece, India, Italy, Spain etc. Marbles are formed by the metamorphism of limestone and dolostone. The word metamorphism means ‘change in form’ and the metamorphic rock is formed by the transformation of an existing rock type, such as sedimentary rock, igneous rock or another older metamorphic rock.
I like to share this Magnetic Dipole Moment Equation with you all through my article.
Minerals present in Marbles
The formation of marble is from limestone by heat and pressure in the earth's crust. These forces cause the limestone to change its texture and makeup, which is known as recrystallization. Marble is the metamorphic rock composed of recrystallized carbonate minerals, most commonly calcite or dolomite. Impurities present in the limestone during recrystallization are responsible for the mineral composition of the marble that forms. These minerals present due to the impurities give marble wide variety of colours. The purest calcite marble is white whereas the marble containing hematite has a reddish colour. The marble with serpentine is green and the marble with limo nite is yellow.

Calcite and Dolomite minerals in marbles
Calcite is a carbonate mineral and it is the most stable polymorph (having more than one crystal structure) of calcium carbonate (CaCO3). The minerals aragonite and vaterite are the other polymorphs. Vaterite is less stable among the three and Aragonite changes to calcite at 470 °C.
Dolomite is the name of a mineral composed of calcium magnesium carbonate CaMg(CO3)2 found in crystals. The mineral dolomite crystallizes in the trigonal-rhombohedral system and forms white, gray to pink, commonly curved crystals, although it is usually massive. The physical properties of Dolomite are similar to those of the mineral calcite. But Dolomite does not rapidly dissolve or effervesce (fizz) in dilutehydrochloric acid unless it is scratched or in powdered form.

Two Forms of Energy
Introduction to Energy:
Energy is a capacity to do some work. Energy can exist in various forms which are mutually convertible. Since the energy is measured in terms of work therefore its units are same as that of work.
There are mainly three types of energy:
Kinetic energy and
Potential energy
Kinetic form of energy
Kinetic energy:
The work done by a body by virtue of its motion is called its kinetic energy.
It is measures by the work it can do against an opposing force before it is brought to rest.
Kinetic energy = work done against the force
= force x displacement
=F x s
Therefore, kinetic energy= (1/2) x mass x square of the velocity
I like to share this Formula for Potential Energy with you all through my article.
Potential form of energy
Potential energy: It is the energy possessed by a body due to its position with respect to another body.
The potential energy of a body with respect to the earth is measured by amount of work in the earth is measures by amount of work in lifting it through a certain vertical height.
A body of mass m is to be raised through a height h. The force with which the body is attracted by the earth is its weight mg to lift the body an equal and opposite force has to be applied.
Potential energy = work done to lift the body
= force x displacement
Potential energy = mg h.
Principle of conservation of energy
The total amount of energy in the universe always remains a constant, that is neither any more energy can be created nor any part of the energy can be destroyed, but energy can be changed from one form into another form
Examples
When a body is projected vertically upwards its velocity goes on decreasing till the velocity is reduced to zero
When the bob of a simple pendulum is displaced from its equilibrium position and then it is release, then its initial PE changes into KE in the vertical position.

Newton's Third Law of Motion
Before discussing about the law of motion let is try to answer a simple question. Imagine walking on the road and you accidentally hit a stone. What do you think happens then? Yes one thing is obvious you can hurt your leg. But let us apply some physics to this and try to find the answer to why this actually happened. When we hit the stone we exerted some force to it. The direction of this force was in line towards the stone.
So some action took place. The next part is interesting. The stone hit us back and this time the line of force was towards our foot. This is when reaction occurred.
I like to share this newton's law of cooling equation with you all through my article.
By now it is clear that the two forces were opposite to each other and were in synchronization with the line of action. Also for an action there was an equal and opposite reaction.
So this is where Newton's third Law of Motion comes into picture. It states that for every action there is an equal and opposite reaction. For every force acting during action an equal and opposite force will act during the reaction. It is important to remember that the forces will be opposite to each other.
Newtons third Law can be mathematically stated as:
F action = - F reaction - - - - - - - - > (1)
Here the minus sign signifies that the forces are opposite to each other. F action is the force of action while F reaction is the force of reaction.
What is Newton’s third law of motion can now be answered very easily. We can take a few example to reinforce our concept.
Is this topic Spin Quantum Number hard for you? Watch out for my coming posts.
We are able to walk because we push the ground and an equal and opposite reactive force makes us walk on the floor. Think of why the wear and tear of tires of vehicles is caused. It is due to the frictional force applied. Similarly let us take an example of a truck and a car colliding with each other.
There will be severe damage to both. This is because both of them have applied forces on each other while they collide. When the ball hits the hands of the catcher then he hurts his hand.
This is because the ball pushes the hand and the hand pushes the ball in turn. It is for the same reason that the catcher in cricket puts his hands down in order to reduce the pressure of ball hitting his hands.

Wind Energy Information
Introduction to information on wind energy :
The energy stored in the moving wind, is called Wind Energy. Kinetic Energy is the main source of energy stored in the winds. Winds are formed due to unequal heating of the land mass and ocean. Moreover, the local conditions and rotations of the earth, demo graphical features of the concerned place, sea, deserts etc , all determine the velocity of the wind. The kinetic energy of the wind is used to generate the electricity.In the recent years, there has been a great interest in producing electric energy from the wind energy, by using windmills, especially in the rural areas. The windmills that generate electricity are conventional in their propeller design, which employs two or tapered blades.
Information on generation of electricity from wind energy:
The shaft of the windmill is connected to the shaft of the armature of the generator. When the fast moving wind rotates the blades of the windmill, its shaft rotates the armature inside the generator. The rotating armature products electric current. Thus, kinetic energy of the wind is converted into electricity.
Having problem with Average Velocity Formula keep reading my upcoming posts, i will try to help you.
Information on Wind Energy Potential :
The amount of electric energy produced depends upon the velocity of the wind. Thus, electric wind machines have been designed which have a capacity of 1MW to 5 MW. The electricity generated by a single windmill is small and cannot be used for commercial purposes. Therefore, a number of windmills are set up over a large area known as wind energy farms. The electric energy produced by harnessing the energy of wind is not very dependable as wind does not blow all the time. Thus, some backup source of electric energy is always needed, when the wind is not blowing. Wind energy farms cannot be established every where. They can be established only at such places, where the wind blows at minimum speed of 15 Km/h for the most part of the year.

Magnetic Flux Unit
Magnetic Flux Unit
Magnetic flux is defined as the product of the magnetic filed (B) and penetrating surface area.
The magnetic flux to the surface is the magnetic lines passing to that surface. The magnetic flux is measured in weber (Wb) or volts-seconds. The magnetic flux unit is also Maxwell.
The magnetic flux (Φ) is defined as;
Magnetic flux (Φ) = B * A;
In the closed surface the magnetic flux is zero. The magnetic flux as we know is the measure of the magnetic lines passing through the surface and for a any surface the field lines coming in and going out are same.
This property makes magnetic material dipole in nature, which means that the magnet always exists with North and South Pole. North and South Pole never exist alone.
I like to share this Calculating Average Atomic Mass with you all through my article.

Law of Conservation of Energy
Define Law of Conservation of Energy
The law of conservation of energy is defined for a system as, “The total amount of energy of a system remains constant with respect to time for the system”. It means that in a system the total energy remains the same.
I like to share this Conservation of Energy Formula with you all through my article.
The Law of Conservation of Energy States that
This law states that the energy contained in any system is constant over time. This law is formulated in nineteenth century. This is one of the fundamental laws of physics and any new study is based on this law. Due to this law it is impossible for any system to possess or destroy more energy then the total energy of the system.
State the Law of Conservation of Energy
The law of conservation of energy state that the total energy of the system remains same or constant when it is measured over time. It also means that the energy of the system may change the position or form in the system but it will always remains the constant.
Definition of Law of Conservation of Energy
The law of conservation is defined as, “In an isolated system, energy could neither be created nor be destroyed; it only changes form and position”. It means that the total energy of the system remains constant. It also means that the energy can change form (kinetic to potential or vice versa) or position in the system.
Law of Conservation of Energy Example
The best example of the law of conservation of energy is the electricity generated by water. Water is stored in dam and then it is allowed to fall down. Water in the dam possesses potential energy but when it is allowed to fall down the potential energy is converted to kinetic energy. This falling water rotates the turbine and the electricity is produced. The energy of water is transferred to the turbine which converts the kinetic energy to mechanical energy. Due to this mechanical energy the turbine rotates and this mechanical energy is converted to electric energy.
In this example we see that the energy is transformed from potential to kinetic to mechanical to electrical, but the total energy of the system remains the constant.
Examples of Law of Conservation of Energy
The example of conservation of energy is the free falling ball. At the start the ball only has potential energy and as it starts falling it gains kinetic energy. As it strikes the ground it only has kinetic energy. Due to the kinetic energy the velocity of the ball increases.
The law of conservation of energy is defined for a system as, “The total amount of energy of a system remains constant with respect to time for the system”. It means that in a system the total energy remains the same.

The example of conservation of energy is the free falling ball. At the start the ball only has potential energy and as it starts falling it gains kinetic energy. As it strikes the ground it only has kinetic energy. Due to the kinetic energy the velocity of the ball increases.

Nutrition Food Choices
Introduction to nutrition food choices:
Procuring, assimilating and utilizing nutrients or food substances for harvesting energy, body building substances for growth, development as well as maintenance and providing protection against diseases is termed as nutrition. It is a vital function for the living being to survive.
Please express your views of this topic Electric Dipole Moment by commenting on blog.
Diet and its importance:
Food is a substance which when taken into the body serves to provide materials for liberation of energy, body structure maintenance, repair, growth of tissues, development, reproduction and resistance to diseases.
Food should not be confused with diet.
Diet is the type and quantity of food and drink planned to meet specific requirement of an individual, for instance vegetarian diet, low caloric diet, diabetic diet, high fibre diet. Dietetics is the branch of science connected with the study of various food stuffs, their nutritional value and use for meeting requirements according to the age and state of health of individuals.
Nutrients are components of food which meet the various requirements of the body for formation of structure, its maintenance, normal functioning, energy, growth, repair, development, etc.
On the basis of their importance to body, food ahs three components – food proper, food accessories and roughage.
Food proper: it contains carbohydrates, proteins and fats; also called proximate principles of food as they immediately become available to the body for liberation of energy, bodybuilding and other organic functions.
Food accessories: they are vitamins and inorganic salts. Food accessories are also called protective principles of food as their deficiency brings about specific diseases and abnormalities.
Roughage: it is a desirable but non-nutrient indigestible component of the food, which is formed of fibrous plant matter, and connective tissues of animal matter. It helps in maintaining the optimum efficiency of digestive tract.
Having problem with Formula for Projectile Motion keep reading my upcoming posts, i will try to help you.
Balanced food or balanced diet:
Balanced food is that diet which possesses all the components of food in quantity and proportion required for maintenance of health, activity, growth and development. It should contain carbohydrates (60 – 70%) fats (15 25%) and proteins (10 – 15%) with vitamins, minerals and roughage.
Conclusion of nutrition food diet:
Every activity of the organism including synthesis of biochemicals, cell division and growth requires energy. Energy is obtained from digested food. Fats give the maximum energy with calorific value of 9.45kcal/g, followed by proteins with 5.65kcal/g and then carbohydrates with calorific value of 4.1kcal/g.

Mixture Science Experiments
Introduction of mixture science experiment:
When two or more compounds or elements mix together in any proportion, mixture is formed. For example when the salt and soil are mixed together, mixture is formed. Mixture science experiments helps us to find out how the component of the mixture. Example mixture of iron, sugar, naphthalene can be separated by using the mixture science experiment. Mixture of soil and sugar can also be separated using the mixture science experiment. A few example of mixture science experiments are described below.
Please express your views of this topic According to the first Law of Thermodynamics by commenting on blog.
To separate the mixture of soil and sugar, a mixture science experiment:
To separate the mixture of soil and sugar, a mixture science experiment is used. For this purpose take 100 ml of water in a beaker and to this add the mixture of soil and sugar. And stir it continuously and heat the beaker up to 30 degree celsius. Sugar gets dissolved in water while the soil suspends in water. Filter the beaker solution, soil residues on the filter paper surface while sugar remains in mother liquor in dissolved state. Evaporate the mother liquor to concentrate it in a china dish. When the volume of mother liquor reduces up to the one by fourth amount of its original volume, place it for recrystillization and keep it undisturbed. Sugar crystal formed in the below of the china dish, and filter it, sugar crystal comes to the surface of filter paper and dried it in a oven at one hundred twenty degree celcius . This gives the sugar enhance by using this mixture science experiment sugar and soil can be separated.

Photovoltaic Solar Energy Conversion
Introduction to Photovoltaic Solar energy conversion:
The term photovoltaic denotes the unbiased operating mode of a photodiode in which current through the device is entirely due to the incident light energy. In this kind of power generation, light energy emitted by the sun is harnessed and is used for the generation of electrical power. This photoelectric cell directly converts light energy into electrical energy. In other words it is a light-powered battery.
Please express your views of this topic Potential Energy and Kinetic Energy by commenting on blog.
Working of a Photovoltaic Cell
A photoelectric cell is built from semiconductor technology. Most commonly silicon is used in the formation of a semiconductor. There are mainly two types of semiconductor. One is ‘p’ type and the other is ‘n’ type correspond to ‘positive’ and ‘negative’. ‘p’ type is abundant in holes whereas ‘n’ type is abundant in electrons. To induce the voltage within a PV cell, two separate semiconductors are sandwiched together. Although both materials are electrically neutral, sandwiching these together creates a p/n junction at their interface, which creates a voltage difference. When the light from the sun hits the cell some of the solar energy is absorbed by the semiconductor material. Using this energy electrons start moving from one terminal to the other. But this charge separation is temporary as electron tends to return to its home terminal because of the attractive force between electrons and positive charges. This can be avoided by using a diode. A diode is a one- way conductor. It allows the current to pass through it in only one direction. When light strikes this cell all the electron tends toward the anode and positive charges towards the cathode and cannot return back because of the presence of diode. The terminal at anode becomes negatively charged and the terminal at the cathode becomes positively charge. In other words a voltage is developed between those two terminals. This acts like a battery and is ready to use.

Robert Brown Brownian Motion
Introduction to Brownian motion:
The movement of particle (random) suspended in a fluid is called Brownian motion. Brownian motion’s mathematical model has several applications in real world. One of which is the stock market fluctuations discussed below in this article. It is one of the simplest time-continuous probabilistic processes. This theory is closely related to that of normal distribution. In both of the theory, their motivation depends on mathematical convenience instead of the accuracy of models.
Please express your views of this topic Equation for Force by commenting on blog.
History of Brownian motion
Thorvald N. Thiele first described Mathematics of Brownian motion in 1880 which was followed by Louis Bachelier’s thesis ‘the speculation theory’ in 1900s which contains stochastic analysis of stock and option markets.
A prediction made by Einstein that, at thermodynamic temperature T, Brownian motion of a particle in a fluid is characterized by a diffusion coefficient.
`D = (k_(B)T)/b`
kB is the Boltzmann's constant and b being the particle’s linear drag coefficient. After a time t, the root mean square displacement in any direction is
`sqrt(2) Dt`
Theory of Brownian motion
A one dimensional model which describes a particle that usually undergoes Brownian motion was published in 1906 by Smoluchowski. The collisions are assumed with M>>m (M is actually the mass of the test particle, whereas m is the mass of any of the singleton particles that composes the fluid). After collision the test particle’s velocity will increase by ?V˜ (m/M) v if V is test particles velocity and fluid particle velocity is v. If the number of collisions from the right is NR and the number of collisions from the left is NL, then the changed particle velocity after N collisions is given by ?V (2NR –N). The multiplicity is then given by:
`(N!) / (N_(R)!) (N - N_(R))!`
And total possible states are 2N. Thus the probability that the particle will hit from the right NR times is
`P_(N)(N_(R)) = (N!) / (2^(N) N_(R)!) (N - N_(R))!`
Unfortunately, 1D model of Smoluchowski's can only explain Brownian motion more qualitatively Assumptions cannot be made for a real particle that undergoes the Brownian motion.
Is this topic Elastic Potential Energy Equation hard for you? Watch out for my coming posts.
Application of Brownian motion to market analysis
It used for the background information.
Brownian motion is used in stock market.
In Optical dynamic trading along with Leverage constraints.
In Price stabilization schemes, investments and uncertainty.
A Brownian motion model is used for decision making.

Definition of Conservation of Energy
Introduction to definition of conservation of energy
Modernization and rapid technology advancements have brought about depletion of natural resources and energy. Energy can be conserved, by using energy efficiently or by reducing the use of energy. Individuals and organizations consuming energy would like to make an effort in conserving it, as it in turn reduces the energy costs and also promotes economic security.
Is this topic Electric Field Strength hard for you? Watch out for my coming posts.
conservation of energy by organizations and industries
Every organization at the end of the day thinks of making profits and by conserving energy which is nothing but reduction in the usage of energy will reap them long term benefits in terms of profits. All these on a larger scale can reduce the need for new power plants, and also may see a reduction in the energy costs. Energy conservation also improves the quality of the environment, by reducing emissions which causes increase in the amount of carbon-di-oxide content in the atmosphere.
Inorder to encourage conservation of energy, government has come up with energy labeling on the electrical appliances. Over usage of energy means depletion of natural resources and fossil fuels. Hence every individual and every organization has to actively take up part in the conservation of energy. Most of the heating and cooling systems consume more energy and hence these energy star ratings have enabled a user to opt for energy efficient electrical appliances. Conservation of energy in turn reduces the emission of greenhouse gases which contributes to climate change, and in this way there is an improvement in the environmental quality.
Having problem with The Formula for Density keep reading my upcoming posts, i will try to help you.
National energy conservation awards are given to industrial units who have made systematic and serious attempts for efficient and effective utilization of energy. Energy managers are appointed in organizations whose job is to reduce the energy usage and thereby conserving the energy. Energy, by far has become the most expensive and non-renewable resource and there is a dire need for conserving it. Thus we had seen the definition of conservation of energy.

What is Digital Modulation
Introduction:
Modulation is the method of changing the carrier signal in according to the message signal. The high-frequency sin waveform acting as carrier signal in the process of modulation. What is digital modulation? Digital modulation means an analog signal of carrier is converted by a digital data bit stream. Digital modulation method is use to convert digital signal to analog and the responding demodulating is applied to convert analog signal to digital signal.
Please express your views of this topic Density of Dry Ice by commenting on blog.
Digital modulation methods:
Let us see about what are methods used in digital modulation,
Phase shift keying
Frequency shift keying
Amplitude shift keying
What is phase-shift keying (PSK)?
It is one of the is a digital modulation process which is used to transfer data signal by changing or converting the phase of an indication signal this wave is known as the carrier wave.
It is used for limited number of phases, every assigned an exclusive set of digits which is should be binary.
Frequently, every phase encodes an equivalent number of bits. Every pattern of bits creates the symbol that is denoted by the particular phase.
The demodulator, which is reassigned particularly for the symbol that set is used by the modulator, find out the phase of the received signal and maps it return to the symbol it denoted, thus getting the original data.
What is frequency-shift keying (FSK) ?
It is a frequency modulation process in that digital message is transmitted during distinct frequency varying of a carrier signal.
The simplest FSK is well-known as binary(0s and 1s) FSK (BFSK).
What is amplitude-shift keying (ASK)?
Is this topic Formula for Friction hard for you? Watch out for my coming posts.
It is a pattern of modulation which denotes digital data as changes at the amplitude of a carrier wave at that time frequency and phase as constant.
The stage of amplitude used to symbolize binary reason 0s and 1s.
A carrier signal acting as ON or OFF switch.
In the output signal, logic 0 is noted by the nonappearance of a carrier, thus giving OFF/ON keying action and therefore the name specified.

What is Electrostatic Attraction
Introduction on What is Electrostatic Attraction
If we bring small bits of paper near a rubber or plastic comb, it is found that the comb does not attract the bits of paper. But if the same comb is first rubbed on dry hair and then it is brought near the paper pieces, it attracts them. Thus an attractive property is developed in the comb due to friction. Similarly when an ordinary glass rod and a piece of silk cloth are separately brought near the bits of paper, they do not attract the bits of paper. But if the glass rod is first rubbed with the silk cloth and then the glass rod and the silk cloth both are brought near one by one near the bits of paper, it is found that they acquire attractive property. The bodies which on rubbing acquire the property of attracting light bodies such as paper pieces etc. are said to be electrified or charged. This charge if not allowed to flow is called static electricity and the branch of electricity which studies the properties of bodies electrified due to stationary charge is called electrostatics.
I like to share this Half Life Practice Problems with you all through my article.
What are the kinds of Electrostatic Charge in Electrostatic Attraction
There are two kinds of electric charges
Positive charge – The charge which is same as that produced on the glass rod when it is rubbed with silk. Conventionally these bodies are called positively charged.
Negative charge – The charge which is the same as that produced on an ebonite rod when it is rubbed with fur. Conventionally these bodies are called negatively charged.
Is this topic Work Formulas hard for you? Watch out for my coming posts.
Methods of charging for Electrostatic Attraction and examples
There are various methods of charging a conductor. They are:
Charging by conduction – A charged body is brought in contact with an uncharged body and the charges are shared.
Charging by induction – A charged body is brought in the vicinity of an uncharged body, without touching such that it gets uncharged on removal of the charged conductor.
An example which we commonly see around and are in sync with electrostatics is the Lightning conductor.
