The body makes 60 complete vibrations in one minute. What is the vibration frequency of this body?

n = 1 / T, where n is the oscillation frequency and T is the oscillation period of a particular pendulum.

T = t / N, where n is the oscillation time, and T is the total number of all oscillations.

Thus, n = 1 / (t / N) = N / t = 60/1 min = 60/60 s = 1 Hz.

Answer: n = 1 Hz.
