N = 50.
t = 1 min 40 s = 100 s.
T -?
v -?
The oscillation period T is the time of one complete oscillation. The oscillation period T is determined by the formula: T = t / N, where N is the number of oscillations, t is the time during which the oscillations were completed.
T = 100 s / 50 = 2 s.
The frequency of oscillations v of the pendulum is the number of oscillations per unit of time. The oscillation frequency v is determined by the formula: v = N / t.
v = 50/100 s = 0.5 Hz.
The oscillation frequency v is related to the period T by the formula: v = 1 / T.
Answer: T = 2 s, v = 0.5 Hz.
