A circular disc is rotating about an axis through its circumference in a vertical plane. If its mass is 0.1 kg and radius 0.5 m, its M.I. In kg. `m^(2)` units about this axis will be

When a circular disc of radius 0.5 m is rotating about its own axis then the direction of its angular momentum is

The kinetic energy of a circular disc rotating with a speed of 60 r.p.m. about an axis passing through a point on its circumference and perpendicular to its plane is (mass of circular disc = 5 kg, radius of disc = 1m) approximately.

A disc of mass 2 kg and radius 0.2 m is rotating about an axis passing through its centre and perpendicular to its plane with an angular velocity 50 rad/s . Another disc of mass 4 kg and radius 0.1m rotates about an axis passing through its centre and perpendicular to its plane with angular velocity 100 rad/s. If the two disc are coaxially coupled, then the angular velocity of coupled system would be

Determine the kinetic energy of a circular disc rotating with a speed of 60 rpm about an axis passing through a point on its circumference and perpendicular to its plane. The circular disc has a mass of 5 kg and radius 1 m.

When a circular disc of radius 0.5 m is rotating about its own axis, then the direction of its angular momentum is
