Question

A pendulum oscillates 25 times in 5 seconds. Find its frequency.​

Answer 1

Explanation:

It is given that,

Number of oscillation of the pendulum is 25

Time taken, t = 5 seconds

We need to find the frequency of the pendulum. We know that the number of oscillation per unit of time is called frequency of an object. It is given by :

f=\dfrac{25}{5}\ Hzf=

5

25

Hz

f = 5 Hz

So, the frequency of the pendulum is 5 Hz. Hence, this is the required solution.

Answer 2

Question

A pendulum oscillates 25 times in 5 seconds. Find its frequency.

Answer

$\boxed{ \bf \:Required \: \: \: Frequency ➪ \: 5 Hz }$

Step Wise Explanation

Frequency can be defined as the number of oscillations made by a pendulum in one second.

It is given that in 5 sec it can oscillates 25 times

$\bf5 \: second \: = 25 \: oscillations \\ \sf 1 \: second = \frac{ \cancel{25}}{ \cancel5} = \pink{5 \: oscillations}$

Thus , Frequency of a pendulum = 5 Hz.
