Question

A pendulum oscilates 50 times in 5 5seconds, find its time period and frequency

Answer 1

Your answer is.........

Answer 2

Given : A pendulum oscillates 50 times in 5 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 = 50/5

→ Frequency = 10 hertz

　

→ Time period = 1/10

→ Time period = 0.1 seconds

　

Therefore,

1. Frequency = 10 hertz.
2. Time period = 0.1 seconds.
