Question

1. The length of a simple pendulum is made
forty oscillations I n one minute. Its time period becomes :​

Answer 1

Answer:

Time period of pendulum is 1.5 sec.

Explanation:

Given Number of oscillations, n= 40

time required for 40 oscillations is, t= 1min= 60 sec

we know, time period (T) is time required for one oscillation.

T = t/n

T = 60/40

T = 6/4

T = 3/2

T = 1.5 sec

Time period of pendulum is 1.5 sec.

This is required answer.
