The variation of angular position `theta`, of a point on a rotating rigid body, with time t is shown in the figure . Is the body rotating clockwise or anti-clockwise?

For uniform circular motion,does the direction of the centripetal force depend on th sense of rotation clockwise or anti-clockwise)?

The variation with time t of the output E of an alternating voltage supply of frequency 50 Hz is shown in the figure. The alternating supply is connected in series with a resistor of resistance 2.4 ohm. Calculate the mean power dissipated in the resistor.

Define angular frequency of rotating body.

The position time graph of a body of mass 2 kg is as given in the figure. What iws the impulse on the body at t = 0 s and t = 4 s.

Point masses m_1 and m_2 are placed at the opposite ends of a rigid rod of length L, and nelgligible mass. The rod is to be set rotating about an axis perpendicular to it. Find the position on this rod through which the axis should pass in order that the work required to set the rod rotating with angular velocity omega_0 should be minimum.

The variation with time t of the output E of an alternating voltage supply of frequency 50 Hz is shown in the figure. State the time t_1 , the peak value E_0 of the voltage, the root mean square voltage E_(rms) , the mean (Average) voltage E_(av)

A rectangular ABCD is roated anticlockwise with a uniform angular velocity about the axis shown in the figure. The axis of rotation of the coil as well as the magnetric field B are horizontal. The induced e.m.f. in the coil would be maximum, when the plane of the coil

Plot the corresponding reference circle for each of the following simple harmonic motions. Indicate the initial (t =0) position of the particle, the radius of the circle, and the angular speed of the rotating particle. For simplicity, the sense of rotation may be fixed to be anticlockwise in every case: (x is in cm and t is in s). x =-2 sin (3t+(pi//3))

Plot the corresponding reference circle for each of the following simple harmonic motions. Indicate the initial (t =0) position of the particle, the radius of the circle, and the angular speed of the rotating particle. For simplicity, the sense of rotation may be fixed to be anticlockwise in every case: (x is in cm and t is in s). x= cos (pi//(6-t))
