Question:

Some clocks that are powered by an AC voltage use the AC frequency to keep time. The power company makes this possible by arranging to have precisely the correct number of cycles that occur every day, which keeps such clocks from gaining or losing time over long periods.
(a) How many cycles of AC voltage are there each day in the United States?
(b) Suppose a clock designed for the United States (where the AC frequency is 60 Hz) is taken to a different country where the frequency is 55 Hz. After one full day at its new location, this clock will be in error by an amount Δt. Find Δt.
