An object that completes 20 vibrations in 10 seconds has a frequency of
A)0.5 hertz.
B)1 hertz.
C)2 hertz.
D)200 hertz.

Question

Quizplus · Accepted Answer

Frequency is the number of vibrations (or oscillations) per unit time. In this case, the object completes 20 vibrations in 10 seconds. Therefore, the frequency can be calculated as:

Frequency = Number of vibrations / Time taken
= 20 / 10
= 2 vibrations per second (or hertz)

Therefore, the answer is choice C) 2 hertz.
