Let $I$ be the moment of inertia of a uniform square plate about an axis $AB$ that passes through its centre and is parallel to two of its sides. $CD$ is a line in the plane of the plate that passes through the centre of the plate and makes an angle $\theta$ with $AB$. The moment of inertia of the plate about the axis $CD$ is then equal to

The coefficient of restitution $e$, for a perfectly elastic collision is

The plate resistance of a triode is $3 \times 10^3 \Omega$ and its mutual conductance is $1.5 \times 10^{-3} A/V$. The amplification factor of the triode is

The x-t graph of a particle performing simple harmonic motion is shown in the figure. The acceleration of the particle at t=2s is:

A metal ring is held horizontally and bar magnet is dropped through the ring with its length along the axis of the ring. The acceleration of the falling magnet is

A black body at $227^{\circ} C$ radiates heat at the rate of $7\, cals / cm ^{2} s$. At a temperature of $727^{\circ} C$, the rate of heat radiated in the same units will be :
