An oscillator completes 240 cycles in 5.2 minutes. Calculate its period (in seconds) and frequency (in Hz).

I. Period = 1.3 seconds

II. Frequency = 0.769 Hertz

Explanation:

Given the following data;

Number of oscillation = 240 cycles

Time = 5.2 minutes.

Conversion:

1 minute = 60 seconds

5.2 minutes = X seconds

X = 60 * 5.2

X = 312 seconds

To find the following;

I. Period

Mathematically, the number of oscillation of a pendulum is given by the formula;

Making period the subject of formula, we have;

Substituting into the formula, we have;

Period = 1.3 seconds

II. Frequency

Substituting the values into the formula, we have;

Frequency = 0.769 Hertz
