The pendulum of certain clock has time period 2.04 s. How fast or slow does the clock run during 24 hours?

Answer

the clock runs 28.8 minutes slowere in one day.

Explanation

The pendulum of the clock has time period 2.03 sec.
Now no of oscillation in 1 day
`=(24xx3600)/2`
=43200
But in each oscillation it is slower by
`(2.04-2.00)=00.04sec`
So in one day it is slower by
`=43200xx(0.04)`
`=28.8min`
so, the clock runs 28.8 minutes slowere in one day.
