Question

A pendulum completes 20 oscillations in 30 seconds. The time period of the pendulum is

Answer 1

Answer:

The time taken to complete one oscillation is known as the time period of the pendulum.

Time Period = (Total time is taken)/ (Number of Oscillations)

Given: - 20 oscillations taking 32s to complete.

Therefore 1 oscillation will take = (32)/ (20) sec = 1.6 second

Therefore 1.6s is the time period of the pendulum.

Answer 2

Explanation:

Given,

No. of oscillations = 20

Time taken = 30 s

To find,

Time period(T) = ?

By definition, time period is the time in which one oscillation is completed. The formula for time period is:

Time period =

$\frac{time \: taken}{number \: of \: oscillations}$

So,

T = 30/20

= 3/2 = 1.5 s

So, the time period of this pendulum is 1.5 seconds.

Hope it helps.

Have a nice day:)
