Question

A simple pendulum takes 36 seconds to complete 30 oscillations. What is the time period of the pendulum?

Answer 1

Answer:

frequency =oscillation/second

f=30/36

f=0.833Hz

time period =1/f

T=1/0.833

T=1.2seconds

Answer 2

Given,

A simple pendulum takes 36 seconds to complete 30 oscillations.

To find,

The time period of the pendulum.

Solution,

We can simply solve this numerical problem by using the following process:

Mathematically,

The time period I'd an oscillating pendulum

= (time gap considered)/(number of oscillations completed in this time gap){Statement-1}

According to the question;

The time period of the oscillating pendulum

= (time gap considered)/(number of oscillations completed in this time gap)

= (36 seconds)/(30 oscillations)

= 1.2 seconds

Hence, the time period of the oscillating pendulum is 1.2 seconds.
