Question

a pendulum oscillates 60 times in 4 seconds find its frequency​

Answer 1

Answer:

given pendulum oscillates 60 times in 4sec

so to find frequency we need it's time period so,

4/60 = 0.06sec.

frequency = 1/ time period

= 1/0.06 = 16.6 hz

I hope it helped you ☺️☺️

Answer 2

Given - Number of oscillations and time

Find - Frequency

Solution - Frequency can be calculated by the formula - number of oscillations/total time taken

Keep the values in formula to find the value of frequency.

Frequency = 60/4

Performing division

Frequency = 15

Hence, the frequency of pendulum is 15 Hertz.
