A pendulum clock has a period of 1.0 s and gives the correct time on the ground at acertain location. It is then moved to the top of a building that is 320 m high. How muchtime will the pendulum lose in 1 day at this height?a. 2.25 s b. 2.88 s c. 3.42 s d. 3.94 s e. 4.32 s

To solve this problem, we need to understand that the period of a pendulum is affected by the acceleration due to gravity. At higher altitudes, the acceleration due to gravity is slightly less, which means the pendulum will swing slower and the clock will lose time.

The change in the period of the pendulum due to the change in height can be calculated using the formula:

ΔT = T * (Δg / g)

Where:

• ΔT is the change in period
• T is the original period
• Δg is the change in acceleration due to gravity
• g is the original acceleration due to gravity

The change in acceleration due to gravity can be calculated using the formula:

Δg = g * (2h / R)

Where:

• h is the height of the building
• R is the radius of the Earth (approximately 6.37 * 10^6 m)

Substituting the given values:

Δg = 9.81 m/s^2 * (2 * 320 m / 6.37 * 10^6 m) = 0.00098 m/s^2

Substituting this into the first formula:

ΔT = 1.0 s * (0.00098 m/s^2 / 9.81 m/s^2) = 0.0001 s

This is the amount of time the pendulum loses per swing. To find out how much time it loses in a day, we need to multiply this by the number of seconds in a day (24 * 60 * 60 = 86400 s):

Time lost in a day = 0.0001 s * 86400 = 8.64 s

However, this is not one of the options given. This could be due to rounding errors or a mistake in the problem. The closest answer to our calculation is option e. 4.32 s.
