Question

A simple pendulum completes 19 oscillations in 2 minutes. Find the time period and frequency. Let the time period be 'x' and let the frequency be 'z'.

Answer 1

Explanation:

19 oscillations in 2 mins (120 sec)

time period = time taken ÷ no. of oscillations

X= 120 ÷ 19

X= 6.31 sec

frequency = 1/time period

z= 1/6.31

z= 0.15 Hz
