Properties of Matter
Remember all objects take up space and have mass. You use your sense of taste and smell to tell the difference between spinach and an orange.
Physical properties- The measurement of mass and other characteristics that can be seen without changing how that object looks are its physical properties. When you look at oranges, you know that they are oranges because of their color, shape, and smell. Mass, color, shape, volume, and density are some physical properties. The answers to the question about the present are physical properties.
Density is an important physical property. Density is the mass of a substance per unit volume. Volume is the amount of space an object occupies.I like to share this Angular Acceleration Formulas with you all through my article.
Chemical properties- These are properties that can only be observed by changing the identity of the substance. A piece of paper burns and turns to a black substance. After the flame goes out you can no longer burn the new substance. The chemical properties have been changed.
Properties are constantly changing...
Matter is constantly changing. Ice in your soda melts, glass breaks, paper is ripped. When ice in your soda melts where does it go? What does it become?
If you remember, ice is water in the solid state. If you don't remember this or don't know it, you should go back and review states of water. When you drop the ice cube into the liquid, it begins to melt because the temperature is higher than that of the ice cube. It's like putting a snowman on your front lawn in July. The ice cube becomes liquid water. This is an example of a physical change. The solid water turned to liquid water. It doesn't turn into soil or macaroni. It remains water. If it did change into soil or macaroni, your drink would taste terrible and you would have an example of a chemical change. Please express your views of this topic What is Electric Charge by commenting on blog.
Chemical changes are changing substances into other substances. If it could happen, ice changing into macaroni would be an example of a chemical change. A real example of a chemical change is spoiling milk or burning toast. Milk needs to be in the refrigerator or else it will go bad. If you've ever seen or smelled spoiled milk, it is not a pretty sight. The milk gets a sour odor and becomes lumpy. Unlike physical changes, you cannot reverse chemical changes. You can melt ice to get water and freeze that water to get ice again. You cannot make milk unspoiled.

Turbine Power Production
Introduction about Turbine Power Production:
Let us see the introduction about turbine power production. The turbine power is the fluid acting as an energy carrier and the production of turbines are like as steam turbine power, gas turbine power, nuclear energy turbine and wind turbine power. The renewable power production turbines are Bio-mass turbine power and geothermal power turbine.
Please express your views of this topic Time Speed Distance Formula by commenting on blog.
Explanation for Turbine Power Production:
Steam Turbine Power:
The steam turbine power plant production is located at conveniently near the load center and hence the transmission cost and transmission losses are reduced.
Device Energy conversion
Boiler Fuel is converted into Heat energy
Turbine Heat energy is converted into mechanical energy
Generator Mechanical energy is converted into electrical energy
Is this topic Definition Kinetic Energy hard for you? Watch out for my coming posts.
Advantages of Steam Turbine Power:
Generation of power production is continuous
Initial cost is low
Less space is required
Disadvantages of Steam Turbine Power:
Transportation and handling of fuel is a major difficulty.
Long time required for erection
Nuclear Energy Power Production:
Nuclear energy is a process of splitting up the nucleus of fissionable material like uranium into two or more fragments with release of enormous amount of energy.
When nucleus of uranium 235 is bombarded with high energy neutrons. The atom split into two fragments there by releasing 2.5 neutrons and enormous amount of energy.
The neutrons are produced very fast and can be to made to fission other nuclei of U235, thus setting up a chain reaction. Let us discuss the nuclear energy problems.
Gas Turbine Power Plant Production:
Natural gas is used as fuel in the gas turbine power plant production and the air is compressed to a high pressure and heated by means of the flue gases.
Advantages of Gas Turbine power Plant Production:
Initial cost is low
Gas turbine power plant production is smaller in size.
Simple in construction and does not require heavy foundations and buildings.

What is Electrical Switch
Introduction to What is Electrical Switch
Electrical switch is a gate for passing of electric power. In a electrical circuit, electric current or power is the flow of electrons which happens through conductors of electricity. Examples of conductors are metals like copper and aluminum. A switch acts as a gate and allows to pass these electrons through when required and stop them when not required. It is the link between two contact points - when closed it allows current to pass through. When a switch is open, it does not allow. I like to share this Electrical Resistance Definition with you all through my article.
What is Electrical Switch : Description
The simplest switch we come across every day is a toggle switch, which is an electro-mechanical switch. Such switches are used to operate the electric lamps at home.
There are several types of switches. SPST or Single Pole Single Through switch is the most common. SPTT or Single Pole Triple Through switch, DPST or Double Pole Single Through switch, DPDT or Double Pole Double Through Switch are other common types of electrical switches.
Having problem with formula for dot product keep reading my upcoming posts, i will try to help you.
What is Electrical Switch : Two way switches
A two-way electrical switch is used in staircase wiring. This switch can be operated either at the bottom of the staircase or n the top of the staircase. Thus, this helps in switching "ON" a lamp while climbing up the staircase and switching "OFF" the lamp after having climbed up. The actions can be reversed when climbing down the staircase - switching "ON" while on top and switching "OFF" after having climbed down.
Materials used to make an Electrical Switch are chosen based upon its electrical conductivity, non-corrosive nature, material hardness, availability, low cost and toxicity. The Electrical conducting part is a good conductor of electricity whereas the non-conducting, handling part is a good insulator. Copper or stainless steel (conductor) is used along with plastic (non-conductor) in making of a switch. Corrosion or oxidation in an electrical switch will prevent easy flow of electrons. The conductive part is usually prone to oxidation and hence it is sometimes coated with non-oxidative or noble metals to prevent oxidation.

Rolling Motion
Rolling and Newton’s first law
A pure rolling is equivalent to pure translation and pure rotation. It, therefore, follows that a uniform rolling (i.e. rolling with constant velocity) is equivalent to uniform translation (constant linear velocity) and uniform rotation (constant angular velocity).
According to Newton’s first law for translation, if net external force is zero, then translation of the object i.e. linear velocity remains same. Similarly, according to Newton’s first law for rotation, if net external torque is zero, then rotation of the object i.e. angular velocity remains same. It means, then, that a body in uniform rolling motion shall roll with the same velocity. I like to share this Projectile Motion Equation with you all through my article.
Note here that when we say that a body is rolling with a constant velocity, then we implicitly mean that it is translating at constant linear velocity and rotating at constant angular velocity. It is so because two motions are tied to each other with the following relation,
vC = ωR
We had difficulty to visualize a real time situation to verify Newton’s first law in translation or rotation, as it was difficult to realize a “force – free” environment. However, we reconciled to the Newton’s first law as we experienced that a body actually moved a longer distance on a smooth surface and a body rotated longer without any external aid about an axle having negligible friction and resistance. In the case of rolling also, we need to extend visualization for the condition of rolling when neither there is net force nor there is net torque.
Please express your views of this topic electrolytic capacitor symbol by commenting on blog.
One such possible set up could be a smooth horizontal plane. If a rolling body is transitioned (i.e. released) on a smooth plane with pure rolling at certain velocity, then the body will keep rolling with same velocity. This statement, if we agree, can be construed to be the statement of Newton’s first law for pure rolling motion.

Define Transverse Waves
Introduction of Transverse Waves:
A progression or travelling types of waves is a disturbance which carries energy from one place to another without transferring matter. There are two types, transverse and longitudinal waves.In define transverse waves; the direction of the disturbance is at right angles to the direction of travel of the waves. Let we see about the types and properties of the transverse waves with diagram. Example: Water waves.
Please express your views of this topic distance physics formula by commenting on blog.
Properties and Types of Transverse Waves:
Properties of Transverse Waves:
Wavelength - Distance between two successive crest or trough and is represented as lambda λ.
Frequency – Number of complete waves generated per second and its unit is Hertz (HZ).
Amplitude – Height of a crest or the depth of a trough measured from the undisturbed position of what is carrying the wave. Example – a rope
Phase: The dot at A, B, C, D, E represents the end of the phase. Let we see about the types of transverse waves.
Types of Transverse Waves:
There are four types of define transverse waves. They are of the following.
Sine Wave – Transverse
Square Wave – Transverse:
Triangle Wave – Transverse:
Transverse Waves Equation:
When the rope is vibrated, the shorter the wavelength of the wave produced. That is, the higher the frequency of the wave, the smaller its wavelength. There is a useful connection between f, λ and v which is true for all type of wave. Therefore we get the define transverse equation is of follow.
Speed of the wave = frequency* (wavelength)
Is this topic capacitor electrolytic hard for you? Watch out for my coming posts.
Example Problems – Define Transverse Waves:
Example 1:
What will the speed of the wave v, when the wavelength of the wave λ is 20 cm travel on a long rope and three crests pass a certain point every second and its frequency is f = 3 HZ?
Solution:
To find: The speed of the wave.
v = f * λ
v = 3 * (20) = 60 cm per sec (60 cm / s).
Answer: v = 60 cm/s
Example 2:
What will be the frequency of define transverse wave, when the speed of the wave is 50 cm / s and the wavelength of wave is 25 cm?
Solution:
To find: The frequency (f) of the wave.
v = f * λ -> f = v / λ
f = 50 / 25 = 2 HZ.
Answer: the frequency of the wave is 2 HZ

Define Seismic Waves
In this article of define seismic waves we will learn what are seismic waves, their types.
When ever sudden breaking of a rock or explosion takes place inside the earth some energy is generated which travels in the form of waves and these waves are called as seismic waves. The propagation velocity of these waves purely depend up on the elasticity and density of the medium through which it penetrates.
The instrument which measures these waves is called seismograph. Now that we defined seismic waves we will learn about types of seismic waves.
I like to share this Example of a Longitudinal Wave with you all through my article.
Types of seismic waves in define seismic waves.
There are different types of seismic of which the most important are body waves and surface waves. body waves travel through the earth's inner layers where as surface waves travel on the surface of earth like ripples on water.
Body waves in define seismic waves:
These waves have high frequency than surface waves and arrive earlier in earth quakes. Body waves are further divided in to P-Waves and S-Waves.
P-waves :
This is the fastest of seismic waves and first to reach seismic station. They can move through solid rocks and liquids. They push and pull the rocks which it moves through same as sound waves push and pull air. These are also known as compressional waves, because of pushing and pulling they do. Some animals like dogs can hear P-Waves but humans cannot do this.
S-Waves :
These are second type of body waves which is the second wave we feel in earth quakes. They can only move through rocks but not liquids. They move the rock up and down or side to side perpendicular to direction which they are moving.
Having problem with equation for wavelength keep reading my upcoming posts, i will try to help you.
Surface waves in define seismic waves:
Traveling on through the crust their frequency is very less than body waves so can be easily distinguished on seismography. But these waves cause more damage during earth quakes. These are further divided in to love waves and Rayleigh waves.
Love waves :
It is named after A.E.H. Love, a British mathematician. It moves ground side to side. it is the fastest surface wave.
Rayleigh waves :
It is named after John William Strutt , Lord Rayleigh, who predicted the existence of this wave.It rolls along the surface of earth same as wave rolls across a lake or an ocean. It moves ground side to side and up and down in the direction which they are moving.
This is all about define seismic waves. Hope you enjoyed it koooollllll....!!!!!

What is a Hydraulic Cylinder
Introduction to hydraulic cylinder
The hydraulic cylinder is a mechanical actuator, which is used for providing the unidirectional force by the unidirectional stroke. It is also called as the linear hydraulic motor. It is used in the several machines and in the engineering departments. Let us discuss the hydraulic cylinder. Please express your views of this topic formula for frequency of a wave by commenting on blog.
What is a hydraulic cylinder?
Hydraulic cylinders are the mechanical machine, which gets the power by the high-pressured hydraulic fluids such as high-pressured oils. The hydraulic cylinder contains a barrel in which a piston rod is connected and it is moving in the back and forth direction. The barrel is closed at both the ends. The piston has some sliding rings and some seals. The chamber of the piston is divided in two parts. The pressure is exerted on the piston so that it can do the linear motion and then perform the useful work. The piston pushes the oil in the other chamber back to the reservoir. If we assume that the oil pressure in the piston chamber, containing the rods is approximately zero, the force FP in the cylinder times the piston area A. on the piston rod equals the pressure
i.e., F = P × A
Parts of hydraulic cylinder
There are several parts of the hydraulic cylinder. The head of the cylinder is sometimes connected to simple lock. The piston actually is short shaped cylinder metallic part that separates the barrel within. It has so many grooves, which is fit in the metal seals. The piston rod is a hard piece of chrome plated of steel which is cold-rolled. Is this topic Permanent Magnet Motor Design hard for you? Watch out for my coming posts.
Types of hydraulic cylinder
There are several types of hydraulic cylinders in the mechanical industry. The main types are tie rod fashioned cylinder and the welded body fashioned cylinder. Let us discuss them. In the tie rod fashioned hydraulic cylinder, there are high powered threaded rods made of steel, which holds the two ending caps of cylinder barrel. Small cylinders have generally four tie rods and large cylinders have 16 tie rods. In the second type of cylinder, there are no tie rods. This barrel is directly welded to the ending caps. The facade rod gland is usually threaded into or is bolted to the barrel of the cylinder, which therefore allows the piston rod assemblage and the rod seal to be detached for service.
