Question

A pendulum oscillates 100 times in 4 second. Find its time period and frequency?

Answer 1

Answer:

you can easily find the solution by the formula given in the book:

Explanation:

ocillations=100 times

Time=4times

frequency=By formula

Answer 2

Given : A pendulum oscillates 100 times in 4 seconds.

　

To find : What is its time period and frequency?

　

Using formula :

1) Frequency = Number of times the pendulum oscillates/Total number of time taken.

　

2) Time period = Number of oscillation per second/Frequency.

　

Calculations :

→ Frequency = 100/4

→ Frequency = 25 hertz

　

→ Time period = 1/25

→ Time period = 0.04 seconds

　

Therefore,

1. Frequency = 25 hertz.
2. Time period = 0.04 seconds.
