v = 2 Hz.
t = 1 min = 60 s.
T -?
n -?
The frequency of oscillations of the pendulum v is the number of oscillations in a time of 1 s. The oscillation frequency v is determined by the formula: v = n / t, where n is the number of oscillations during time t.
n = v * t.
n = 2 Hz * 60 s = 120.
The oscillation period T is the time of one complete oscillation. The oscillation period T is determined by the formula: T = t / n = 1 / v.
T = 1/2 Hz = 0.5 s.
The period T is the reciprocal of the frequency v.
Answer: the pendulum will make n = 120 oscillations, the oscillation period is T = 0.5 s.
