I am pretty sure it is A Becoming warm
Since it’s moving and causing friction which makes it warm
Hope this helps
Mark me brainliest
Is there suppose to be an image?
Answer:
d) shortening the string
Explanation:
Time period of a pendulum clock is dependent on two factors namely:length and acceleration due to gravity.
When a clock loses time, the time period of the pendulum clock increases.
This however can be corrected by decreasing the length of the pendulum.The time period of the pendulum clock is not dependent on the mass of the bob. The time period of the pendulum clock can be corrected only by changing the length of the pendulum string.
Anything times zero is zero
