Question

. A simple pendulum makes 20 oscillations in 1 second. What is the time period of its oscillation?​

Answer 1

Answer:

20 sec is the time period I think so

Answer 2

Explanation:

It is given that,

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

Time taken, t = 01 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 :

$\tt \: f=\dfrac{20}{01}\ Hz=20\ Hz$

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

$\tt \: f=\dfrac{1}{t} \\ \\ \tt \: t=\dfrac{1}{20\ Hz} \\ \\ \tt \: t = 1/20 sec$

Hence, this is the required solution.
