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.

The molar heat capacity of a gas at constant pressure is 18.7 J mol -1 K -1 . What is the heat capacity of 9.4 moles of this gas at constant volume ?
Pitch is the tone of the note/ssong. (high or low) intensity involves speed, loudness, business and strength in a piece.
In the circuit shown below, a potentiometer is used to vary the current to the lamp. If the only resistance is due to the lamp, what is the current in the circuit?
POSITIVE ACCELERATION: If velocity of a body is enhancing, then its acceleration is said to be positive. The direction of positive acceleration is similar as that of velocity.
