Question

A "grandfather’s" clock is based on a pendulum of length exactly 1 m at temperature -20 °C. If the clock is taken to a location at –30 °C, the clock...

a. Will run faster
b. Will run slower
c. Will not be affected
d. Not mentioned

Answer 1

A grandfather's clock will run faster when taken to a location with a lower temperature.

Step-by-step explanation:

When the temperature decreases, the length of the pendulum decreases as well. This causes the clock to run faster because the period of a pendulum is directly proportional to its length. When the length decreases, the time it takes for one complete swing also decreases, resulting in the clock running faster.

Therefore, the answer is a. Will run faster.
