A boy is sitting on a horizontal platform in the shape of a disc at a distance of 5m from its centre. The boy begins to slip when the speed of wheel exceeds 10 rpm The coefficient of friction between the boy and platform is&nbsp;(g = 10 ms–2)

Statement A: Lyophilic colloids are more stable than lyophobic colloids.Statement B: In lyophobic system, the dispersed particles are more solvated than in lyophilic system.

The change of position of a particle in a specified direction is called&nbsp;

The magnitude of the physical quantity is&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

Intensity of the scattered light depends upon the difference of which of the following property of the dispersed phase and the dispersion medium?

A cricket ball of mass 100 g is moving with a velocity of 10 m s–1 and is hit by a bat so that it turns back and moves with a velocity of 20 m s–1. Find the impulse and the force if the force acts for 0.01 s.

A boy is sitting on a horizontal platform in the shape of a disc at a distance of 5m from its centre. The boy begins to slip when the speed of wheel exceeds 10 rpm The coefficient of friction between the boy and platform is
