A pendulum consists of a large weight suspended by a steel wire that is 0.9500 m long.

Question:

(a) If the temperature increases, does the period of the pendulum increase, decrease, or stay the same? Explain.

(b) Calculate the change in length of the pendulum if the temperature increase is 150.0 C°.

(c) Calculate the period of the pendulum before and after the temperature increase. (Assume that the coefficient of linear expansion for the wire is 12.00 × 10-6K-1, and that g = 9.810 m/s2 at the location of the pendulum.)
