Question 5
A pendulum oscillates 40 times in 4 seconds. Find its time period and frequency.

Answer 1

The frequency of oscillations is the number of oscillations of a vibrating object per second. Therefore frequency = 40 vibrations /4 seconds= 10 Hertz. Time period is the time required to complete one oscillation. Frequency is the inverse of the time period. Therefore time period $=\frac{1}{10}=0.1seconds$.
