Answer :
Final answer:
The length of the pendulum in a grandfather clock is stipulated as 1.55 meters in the question. This pendulum regulates the ticking of the clock, marked by the maximum displacement of the pendulum in each direction. Changes in gravitational pull or temperature could require adjustments to maintain time accuracy.
Explanation:
According to the question, the length of the pendulum in a grandfather clock is given as 1.55 meters. The pendulum is the crucial component regulating the tick of the clock. The ticking happens each time the pendulum reaches its maximum displacement in either direction, and any changes in length of the pendulum may affect the accuracy of the clock. In the instances of moving to a location with a different gravitational pull or if the pendulum length changes due to temperature effects, appropriate adjustments would have to be made to ensure the clock keeps accurate time.
For example, if you move from one city to another where the acceleration due to gravity is slightly greater, you would have to shorten the pendulum to keep the correct time because a longer pendulum swings slower. Conversely, in a location with weaker gravity, you would need to lengthen the pendulum. Similarly, materials may expand or contract with temperature changes, altering the pendulum length and, consequently, affecting the timing of the clock.
