Explanation:
It is given that,
Number of vibrations, N = 20
Time taken, t = 100 s
2. The total number of vibrations per unit time is called the frequency of the object. It is given by :
f = 0.2 Hz
1. The reciprocal of the frequency of the particle is called its time period. It is given by :
T = 5 seconds
Hence, this is the required solution.
