VELOCITY OF APPROCH/SEPARATION

CHARGING OF THE CAPICITOR-OTHER APPROCH

STATEMENT-1 : In an elastic collision between two bodies, the relative velocity of separation equals relative velocity of approach. and STATEMENT-2 : In a elastic collision , the coefficient of restitution is 1 .

A potential barrier V volts exists across a P-N junction. The thickness of the depletion region is 'd'. An electron with velocity 'v' approches P-N junction from N-side. The velocity of the electron acrossing the junction is.

Approach/Separation Velocity || Relative Angular Velocity

A train is passing a stationary observer at station with constant velcity. If the frequency observed by the person during its approches and recession are 2.2 kHz and 1.8 kHz respectively. Then find the velocity of train if the velocity of sound in air in air is 300 m//s .

A car is approching a railway crossing at a speed of 72 kmph . It sounds a horn, when it is 800 m away, at 600 Hz . If the velocity of sound in air is 330 ms^(-1) . The apparent frequency as received by a man at rest near the railway track perpendicular to the road at a distance of 600 m from the crossing the

Assertion :- velocity time graph of two paticles undergoing head - on collison is shown in the figure. If collision is inelastic then value of y must be less than x . Reason :- Coefficient of restitution (e)=(|"velocity of separation"|)/(|"velocity of approach"|)

The phase difference between two points separated by 1m in a wave of frequency 120 Hz is 90^(@) . The wave velocity is

The phase difference between two points separated by 0.8 m in a wave of frequency 120 Hz is 90^(@) . Then the velocity of wave will be
