Doppler Effect
Describing the classical Doppler Effect for sound waves. The Doppler Effect is a means through that wave properties (specifically frequencies) are influenced through the movement of a source or listener. If you've ever been waiting at a railroad crossing and listened to the train whistle, you've in all probability noticed that the pitch of the whistle changes as it moves associatively to your position. Same, the pitch of a siren change as it approaches and then passes you on the road.
What occures to Internal Energy of a system ,if work is done (a) on the system, (b) by the system.
Core losses or Iron losses: These losses having of hysteresis and eddy current losses, which happen due to pulsation of flux in the core. These losses depend upon the maximum flux
