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.
CENTRE OF GRAVITY: Consider a body as an accumulation of many small masses (molecules), all subject to gravitational attraction. The total weight, which is a force , is
They are exactly analogous to water pressure and water flow by a hose. That's why flowing electrons is known as a current, just like a water current. Voltage is the electromotiv

Forces on a Pendulum The weight, force because of tension, and total force exerted on the bob of a pendulum are displayed.
A 12 volt battery is associated across a series combination of two capacitors C1 and C2. The capacitance of C2 is double that of C1.
Tiger Woods can hit a golf ball with 55 N of force. How hard does the ball hit back on the club? (a) more than 55 N of force, (b) less than 55 N of force, (c) exactly 55 N of force
