t = 24 s
N = 12
T-?
f-?
The oscillation period T is the time of one complete oscillation. Since the body made 12 vibrations in t = 24 seconds, then T = t / N. T = 24 s / 12 = 2 s.
The frequency of oscillations f is the number of oscillations in 1 second. Since N = 12 vibrations are done in t = 24 seconds, then f = N / t. f = 12 / 24s = 0.5Hz
Answer: T = 2 s, f = 0.5Hz.
