A pendulum clock keeps correct time at . If the room temperature increases to , the clock will:
- A.lose timeCorrect answer
- B.gain time
- C.neither gain nor lose time
- D.stop working
Solution
As temperature increases, the length of the pendulum increases (). The time period increases, meaning each oscillation takes longer than standard. Consequently, the clock completes fewer oscillations per hour and thus loses time.
