A constant resultant torque rotates a wheel about its own axis. Then true statement of the following is

The rotation of earth about its axis is

The earth rotates about its own axis, then the value of acceleration due to gravity is

A wheel is free to rotate about its own axis without friction. A rope is wound around the wheel. If other end of rope is pulled with a constant force, then true statement from the following is

Many great rivers flow toward the equator. The sediments that they carry, increases the time of rotation of the earth about its own axis. The angular momentum of the earth about its rotation axis is conserved.

A wheel having moment of inertia 2 kg m^(2) about its vertical axis, rotates at the rate of 60 rom about this axis. The torque which can stop the wheel's rotation in one minuted woould be

A wheel whose radius is R and moment of inertia about its own axis is I, rotates freely about its own axis. A rope is wrapped on the wheel. A body of mass m is suspended from the free end of the rope. The body is released from rest. The velocity of the body after falling a distance h would be:

How many degrees does the Earth rotate about its own axis in one hour?
