Unformatted text preview: 3. A simple pendulum is made up of a 2.0 kg mass suspended on a thin aluminum wire.
This pendulum has a period of exactly 4.0 s when operated near the equator at a
temperature of 122°F. The pendulum is then moved to an Antarctic weather station
where the temperature is — 49°F. The linear coefficient of thermal expansion for aluminum is 24 x 10‘6/°C. a. (10 points) What is the length of the pendulum Wire at the equator?
b. (10 points) What is the period of the pendulum at the Antarctic weather station? ...
