Answer to Question #243546 in Molecular Physics | Thermodynamics for Cjts

Question

A pendulum makes 90 vibrations in a minute.

a.) Find the period T in seconds.

b.) What is its frequency?

Answer 1

$a.\\ T= (a/60_s)/90=\\ =\frac{a}{{60}\times{90}}\\ =\frac{a}{5400}\; s$

b.

$F=\frac{1}{T}\\ =\frac{5400}{a}\;\;Hz$
