Question

two simple pendulums, a and b, are each 5.0 m long, and the period of pendulum a is t. pendulum a is twice as heavy as pendulum b. what is the period of pendulum b?

Answer 1

P = 2 π (L / g)^1/2 describes period of a simple pendulum

The period of the pendulum does not depend on the mass (weight)

Pendulum b has the same period (frequency) as pendulum a
