The period of the second pendulum is 0.9 s
Explanation:
The period of a simple pendulum is given by the equation
where
L is the length of the pendulum
g is the acceleration of gravity at the location of the pendulum
For the first pendulum, we have
L = 0.64 m
T = 1.2 s
Therefore we can find the value of g at that location:
Now we can find the period of the second pendulum at the same location, which is given by
where we have
L = 0.36 m (length of the second pendulum)
