Answer:
I. Time period = 0.2 seconds.
II. Frequency = 5 Hertz.
Explanation:
<u>Given the following data;</u>
Time, t = 5 seconds.
Number of oscillation, n = 25 times
<em>I. To find the time period;</em>
Substituting into the equation, we have;
<em>Time period = 0.2 seconds. </em>
<em>II. To find frequency;</em>
Substituting into the equation, we have;
<em>Frequency = 5 Hertz.</em>
<em>Therefore, the time period and frequency of the pendulum is 0.2 seconds and 5 Hertz respectively. </em>
