Question

a simple pendulum takes 18 sec. to complete 10 ocillations.what is the time period of the pendulum?for class 7 sort answer​

Answer 1

Hey mate.

Here is your answer-

let,

A simple pendulum is given..

It takes 18 sec for 10 oscillation

So for 1 oscillation = 18/10 sec

Therefore, the time period of simple pendulum is 1.8 sec.

Or.

t = 18 sec

No of oscillation = 10

So, using formula

Time period of oscillation = time taken / no. of oscillation

= 18/10

1.8 sec

Therefore, the time period of simple pendulum is 1.8 sec.
