Moment of inertia of a square plate of side l about the axis passing through one of the corner and perpendicular to the plane of square plate is given by :

An ideal gas is expanding such that PT³ = constant. The coefficient of volume expansion of the gas is :

In a photoelectric experiment, increasing the intensity of incident light :

A bar magnet is passing through a conducting loop of radius R with velocity $$\upsilon $$. The radius of the bar magnet is such that it just passes through the loop. The induced e.m.f. in the loop can be represented by the approximate curve :
