Question

A simple pendulum takes 32 seconds to complete 20 oscillations. What is its
time period?

Answer 1

Answer:

$= step \: by \: step \: solution: \\ = time \: taken \: by \: the \: pendulum \: to \: complete \: 20 \\ oscillations = 32s \\ \\ = time \: taken \: by \: the \: pendulum \: to \: complete \: 1 \\ oscillation = \frac{32}{20}s = 1.6s \\ \\ hence, \: the \: time \: period \: of \: the \: pndulum \: is \: 1.6 \: seconds.$
