For the same number of oscillations, 1 pendulum will take 5 seconds and 2 pendulum 15 seconds. Compare the period and frequency of the pendulums.
t – time T – period V – frequency n – number of oscillations
Given: n1 = n2 t1 = 5sec t2 = 15sec
Solution: T1 = t1 / n T2 = t2 / n => T1 / T2 = t1 / t2 = 5/15 = 1/3 V1 = n / t1 V2 = n / t2 => V1 / V2 = t2 / t1 = 15 / 5 = 3
Answer: T1 / T2 = 1/3; V1 / V2 = 3.
