Question

A pendulum oscillates 25 times in 5 seconds calculate itrs time period and frequency​

Answer 1

Answer:

I. Time period = 0.2 seconds.

II. Frequency = 5 Hertz.

Explanation:

Given the following data;

Time, t = 5 seconds.

Number of oscillation, n = 25 times

I. To find the time period;

$Time \; period = \frac {time}{number \; of \; oscillations}$

Substituting into the equation, we have;

$Time \; period = \frac {5}{25}$

Time period = 0.2 seconds.

II. To find frequency;

$Frequency = \frac {1}{Time \; period}$

Substituting into the equation, we have;

$Frequency = \frac {1}{0.2}$

Frequency = 5 Hertz.

Therefore, the time period and frequency of the pendulum is 0.2 seconds and 5 Hertz respectively.
