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.
Two charges eachof q=+2 micro coloumb are placed at the vertices Q and R of the triangle .the sum of sides PQ and PR is 12cm and their product is 32 cm_2 .the potential at point P

Three impedances are connected in series across a 100V, 2kHz supply. The impedances comprise: (i) An inductance of 0.45mH and 2 resistance, (ii) An inductance of 570µH a
IMPULSE: When a force acts on a body for a very short time, the product of the force and the time for which the force acts, is called the impulse or impulse of force".
