Joule's laws (J.P. Joule)
Joule's first law
The heat Q generated while a current I pass through a resistance R for a particular time t is given by following
Q = I2 R t
Joule's second law
The internal energy of an ideal gas is independent of its volume & pressure, depending on its temperature only.
Molecules: Let us take a piece of matter, for example, a drop of water and see what happens when it is sub-divided into smaller and smaller portions. The drop is first cut
Example of like and unlike parallel forces

Two travelling sinusoidal waves are described by the wave functions Y1 = 55.00 sin[π(4.00x - 1200t)] Y2 =55.00 sin[π(4.00x - 1200t - 0.250)] where x, Y1 , and Y2 are in meter
Q. Define: binding energy. The energy equal of mass defect is called as binding energy. ∴ Binding energy = [Zm P + Nm n - m] c 2 = Δm c 2 . Here, Δm is the mass defe
