Question

a simple pendulum complete 40 oscillation in one minute .find its frequency and time period​

Answer 1

Answer:

Number of oscillations in 1 minute = 40

Number of oscillations per second = 40/60 = 0.66

Hence, frequency = 0.66 Hz

Time period = 1 / 0.66 = 1.51 sec

Answer 2

Answer:

time period= 40

frequency=1

Given- 40 oscillation in one minute

to find- frequency and time period

solution:-

time period=no.of oscillation/time taken

frequency= no. of oscillation/time period
