The body made 20 oscillations in 10 seconds to determine the period and frequency of such oscillations.

Given:
n = 20
t = 10 s
To find:
T (period)
v (frequency)
Decision:
The period can be found using the formula:
T = t / n
T = 10/20 = 0.5 (s)
The frequency is found by the formula:
v = 1 / T
v = 1 / 0.5 = 2
