Question

if the frequency of a simple pendulam is 50 hz . Calculate the time taken by the pendulum to complete 20 ocillations.​

Answer 1

Answer:

Explanation:

here,

f = 50 hz

cycle = 20 ocillations

time = ?

as

t = 1 / f

t = 1 / 50

t = 0.02 s

therefore, the time peiod of one osicllation is 0.02 s

∴ time period of 20 osicllation = 0.02 * 20

                                                          0.4 s
