Question

A simple pendulum complete 40 oscillations in one minute find its frequency and time period ​

Answer 1

Answer:

frequency = 0.667Hz

time period = 1.5sec

Explanation:

Given

Number of Oscillations, N = 40

Time t = 1min

Frequency f=  N /t = 40 / 60 =0.667Hz

Time period, T=  1 /f =1.5sec

Hence, frequency is 0.667Hz and time period is 1.5sec

Answer 2

Answer:

Hence, frequency is 0.667Hz and time period is 1.5sec

Explanation:

Frequency(F) = N/T = 40/60 = 0.667

Time period = 1/F = 1.5
