ASSALAMUALAIKUM

__________________________________________

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 :

$\sf f=\dfrac{20}{40}\ Hz=0.5\ Hz$

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

$\sf f=\dfrac{1}{t}$

$\sf t=\dfrac{1}{0.5\ Hz}$

t = 2 seconds

Hence, this is the required solution.

Answer:

F = 1/T

F=20/40=1/2hz

T=1/f

T=1/1/2=2s

Explanation:
