What is meant by axis of rotation ?

A body having a moment of inertia about its axis of rotation equal to 3 kg m^(-2) is rotating with angular velocity of 3 rad s^(-1) . Kinetic energy of this rotating body is same as that of a body of mass 27 kg moving with velocity v. The value of v is

A circular coil of 16 turns and radius 10 cm carrying a current of 0.75 A , rests with its plane normal to an external field of magnitude 5.0xx 10^(-2) T . The coil is free to turn about an axis in its plane perpendicular to the field direction. When the coil is turned slightly and released it oscillates about its stable equilibrium with a frequency of 2.0s^(-1) . What is the moment of inertia of the coil about its axis of rotation ?

What will be the moment of force taken about a point and actng on the axis of rotation ?

Write the value of the magnetic moment of an electron related to orbital motion of an electron and spin motion of an electron .
