Question

Which factor listed below has the greatest effect on the period of a pendulum?

a
Mass of the pendulum
b
Angle of the pendulum
c
Length of the string
d
Amplitude of the oscillations

Answer 1

C

Step-by-step explanation:

equation for pendulum period is

`\mathrm{T}=2 \pi \sqrt{\frac{\mathrm{L}}{\mathrm{g}}}`

and it depends only on its length (and gravity which is not on the list of answers)
