A pendulum is made up of a 2.0 kilogram mass suspended on thin aluminum wire. This pendulum has a period of exactly 4 second when operated near the equator at a temperature of 122F. The pendulum is then moved to an Antarctic weather station where the temperature is -44F. The linear coefficient of thermal expansion for aluminum is 24x10-6/C.

a. Find the length of the pendulum wire at the equator?

b. Find the period of the pendulum at the Antarctic weather station?
