(a) State the postulate of STR and deduce Lorentz Transformation.
OR
Give basic postulate of special theory of relativity. Derive Lorentz Transformation equations.
(b) Prove that particle having rest mass zero is always moving with velocity of light.
why CPH has speed Vc and Vc is greater than c? Answer; since you know photon has spin. Thus the path per time of a point on photon is greater than c it means the speed of photo
An object with a mass of 5 kilograms is a distance of 5 meters above the surface of the earth. If the acceleration because of gravity is 10 meters per second squared, the pote
Specific heat of a gas is numerically equivalent to the amount of heat essential to raise the temperature of unit mass of gas by 1 0 C. In order to raise the temperature of unit ma
Q. Explain the magnetize of metal? Answer:- You can rub a magnet alongside the metal in one direction for a bunch of times (the more the better) and that will magnetize it
Explain about the Homojunction Laser in brief. Homojunction Laser: Assume that GaAs be doped with T providing n-type material and with Ge providing p-type material. In forwa
A solar cell or photo voltaic cell is a semiconductor device that converts photons from the sun into electricity. It can also be defined as a semiconductor electrical junction appa
determine the pressure of a 20 lb force applied to an area of 10 inch squared
measurement and calculation with formula
In Rutherford's experiment including the deflection of alpha particles by atomic nuclei, the fact that some of the alpha particles bombarding the thin gold foil were back-scattered
When we move from a positive charge towards an equal negative charge along the line joining the two then initially potential reduces in magnitude and at centre changes into zero, b
