A Carnot engine operates between temperatures 500 K and 300 K. Its efficiency is:

A body of mass m is executing SHM with amplitude a and frequency f. The average kinetic energy during one oscillation is:

A car moves on a level road with speed v. The maximum speed at which it can take a turn of radius r without skidding is (mu = coefficient of friction):

Two strings of different linear mass densities μ₁ and μ₂ are joined together at one end. The combined string is stretched with uniform tension T and both ends are fixed. The lengths of the two segments are L₁ and L₂ respectively. If the junction point is a node, the possible angular frequencies of normal mode vibration are:
