Question

If a pendulum oscillates 404 times in 4 seconds find its time period and frequency​

Answer 1

Answer:

Time period is 0.009 second

Frequency is 101 Hz.

Explanation:

Given,

a pendulum oscillates 404 times in 4 seconds.

To find: its time period and frequency​

Solution:

Time period is defined as time taken by pendulum to complete one oscillation.

here, Time taken for 404 oscillations = 4 sec

then, Time taken for 1 oscillation = 4 / 404 = 0.009 second

Therefore, Time period is 0.009 second

And, Frequency is defined as number of oscillations per second,

then, F = 404 / 4 = 101

Therefore, Frequency is 101 Hz.
