Answer:
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 :
f=\dfrac{20}{40}\ Hz=0.5\ Hzf=4020 Hz=0.5 Hz
The relation between the time period and frequency is given by :
f=\dfrac{1}{t}f=t1
t=\dfrac{1}{0.5\ Hz}t=0.5 Hz1
t = 2 seconds
Hence, this is the required solution.
