Question

A simple pendulum makes 20 oscillations in 40 seconds . What is the time period and ferquency of oscillations ??​

Answer 1

Answer:

Step-by-step explanation:

It is given that,

Number of oscillations made by the simple pendulum, N = 20

Time taken, t = 40 seconds

Let T is the time period of its oscillation. The total number of oscillations per unit time is called frequency of the simple pendulum. It can be calculated as :

The relation between the time period and frequency is given by :

t = 2 seconds

Hence, this is the required solution.
