A pendulum has a length of 1m. What is the period of this pendulum? What is the frequency of this pendulum?
You measure the period of a pendulum and get 25s. What is the length of the pendulum?
he period of a pendulum is independent of its mass:
T= 2*pi*sqrt(l/g)(is seconds)
frequency = 1/T
if you have T 25s and g 9.81 m/s²
you can find l for T=25s :)
