* A simple pendulum takes 42 s to
complete 30 oscillations. What is the
time period of the pendulum?​

Answer 1

⛦ Given :

• Time taken = 42 s.
• Number of oscillation = 30

⛦ To find :

• Time period of pendulum.

⛦ Solution :

Here, in the Question the pendulum takes 42 sec.(time) to complete 30 oscillations.

•We know that,

Time period of pendulum :

$\dashrightarrow\sf\dfrac{Time \ taken}{No. \ of \ oscillation}$

A/Q

$\sf{Time \ period=}\dfrac{\cancel{42}^7}{\cancel{30}^5}$

$\sf{Time \ period=}\dfrac{7}{5}$

$\sf{Time \ period=1.4 \ second.}$
