- If a flywheel increases its speed from 10 rpm to 20 rpm in 10 seconds, then its angular acceleration is
- A ball of mass 250 g moving on a smooth horizontal table with a velocity of 10 m/sec hits an identical stationary ball ‘B’ on the table. If the impact is perfectly plastic, the velocity of the ball ‘B’ just after impact would be
- Ball ‘A’ of mass 250 g moving on a smooth horizontal table with a velocity of 10 m/s hits an identical stationary ball ‘B’ on the table. If the impact is perfectly elastic, the velocity of the ball ‘B’ just after impact would be
- The diagram showing the point of application and line of action of forces in their plane is called
- One end of a light string 4 m in length is fixed to a point on a smooth wall and the other end fastened to a point on the surface of a smooth sphere of diameter 2.25 m and of weight 100 kg. The reaction between the sphere and the wall of the arrangement made is
- A rigid body suspended vertically at a point and oscillating with a small amplitude under the action of the force of gravity, is called
- When a body falls freely under gravitational force, it possesses
- Moment of inertia of a squares of side ‘b’ about an axis through its centre of gravity, is
- When two forces, each equal to P, act at 90° to each other, then the resultant will be
