Question

A simple pendulum makes 10 oscillations in 20 seconds. What is the time period and frequency of its oscillation?

Answer 1

Explanation:

First calculate frequency,

Since, by the defination frequency is the no of oscillations in one second.

here, no of oscillations is 10 and time is 20 sec.

$f = n \div t$

where n is oscillations and

t is time .

frequency=10/20=0.5 hz

•time=1/f

therefore time= 2 sec
