Write definition of instantaneous velocity

Write definition of beat.

Write the formula of instantaneous velocity of SHM particle along X-axis.

Write definition of capacitance.

In Exercises 3.13 and 3.14, we have carefully distinguished between average speed and magnitude of average velocity. No such distinction is necessary when we consider instantaneous speed and magnitude of velocity. The instantaneous speed is always equal to the magnitude of instantaneous velocity. Why?

Assertion: In general |Displacement| le distance. Reason: The instantaneous speed is equal to the magnitude of the instantaneous velocity,

Write definition of critical angle.

A man moves in x-y plane along the path shown. At what points is his average velocity vector in the sam direction as his instantaneous velocity vector. The man starts from point P .

A particle is projected with a speed v and an angle theta to the horizontal. After a time t, the magnitude of the instantaneous velocity is equal to the magnitude of the average velocity from 0 to t. Find t.
