A pendulum oscillates 40 times in 4 seconds. Find its time period and frequency.

True or False The number of oscillations per second of a vibrating object is called its time period.

A bar magnet suspended freely has period of oscillation of 2s. Now, the bar magnet is broken into equal halves and one-half is suspended to oscillate freely in the same magnetic field. Find the time period of oscillation of this half of the magnet.
