Question on: WAEC Physics - 2018
The bob of a simple pendulum takes 8.0s to complete 10 oscillations. Determine the frequency of oscillation of the bob.
A
0.125Hz
B
1.25Hz
C
7.50Hz
D
8.00Hz
Ask EduPadi AI for a detailed answer
Correct Option: B
10 complete oscillations = 8.0s
1 complete oscillation (period) = \(\frac{8}{10}\)s
Frequency = \(\frac{1}{period}\) = \(\frac{1}{0.8} = 1.25Hz\)
