Answer 2

Calculation of Clock Delay

To calculate the delay in the clock due to the elongation of the pendulum, we can use the formula for the period of a simple pendulum:

T = 2π√(L/g)

Where: - T is the period of the pendulum, - L is the length of the pendulum, and - g is the acceleration due to gravity.

In this case, the original length of the pendulum is 55.8 cm, and we need to find the delay when the pendulum is elongated by 0.5 cm.

Let's calculate the delay:

1. Calculate the original period of the pendulum: - L = 55.8 cm - g = 9.8 m/s^2 (approximate value for gravity) - Convert L to meters: 55.8 cm = 0.558 m - Substitute the values into the formula: T = 2π√(0.558/9.8) - Calculate T using a calculator or math software.

2. Calculate the new period of the pendulum with the elongated length:
