Question #2d583

Answer 1

As the length of the pendulum increases, the period increases according to the formula

Using this formula, a pendulum with a 1.0 m length on Earth, with an average `g=9.80m/s^2` would have a period (T) of approximately 2.0 s.

Because the length is under the square root, in order to cut the period in half, you need to make the length 1/4 of its original.
