Relativity principle:
The principle, employed through Einstein's relativity theories, that the laws of physics are the similar, at least qualitatively, in all of frames. That is, there is no frame which is better (or qualitatively any different) from any other. This principle, along the constancy principle, constitutes the founding principles of special relativity.
two bodies of masses 200 g and 300 g are tied to a string which is passed over a pully.if pully has no weight and friction,then find the accerlation of the bodies and tension in th
Electromagnetic waves are transverse waves; that means magnetic vector and electric vector, propagation vector are perpendicular to each other. Prove the statement mathematically.
