Question

A clock which has previously kept perfect time has its pendulum length increased by 8.09 percent at exactly noon. Twenty four hours later, by what amount will the clock be incorrect?

Answer 1

When the length of a clock's pendulum is increased by 8.09 percent, the clock will be incorrect by approximately 1.9436 hours after 24 hours.

Step-by-step explanation:

A clock's accuracy is determined by the length of its pendulum. When the length of a clock's pendulum is changed, it affects the time it reads. In this case, the pendulum length is increased by 8.09 percent. To calculate the amount by which the clock will be incorrect 24 hours later, we can use the formula:

Change in time = 24 hours x (Change in pendulum length / Original pendulum length)

Substituting the values, the change in time will be: 24 hours x (8.09/100) = 1.9436 hours.
