A grandfather clock's pendulum has a period of 4.5 seconds. What is its frequency? Round to the nearest hundredth.

Answer: 0.22hz

Step-by-step explanation:

Hi to answer this question we have to analyze the information given:

Period (T) = 4.5 Seconds

So, to calculate the frequency of the pendulum we have to apply the formula;

Frequency (f) = 1 / period

Replacing with the value given:

f = 1 / 4.5 sec = 0.22 hz
