Question

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

Answer 1

The pendulum of the clock has time period 2.03 sec.

Now, no. of oscillation in 1 day

$=\frac{24\times 3600}{2}$

$=43200$

But, in each oscillation it is slower by

$(2.04-2.00)=0.04sec.$

So, in one day it is slower by

$=43200\times \left(0.04\right)$

$=28.8min.$

So, the clock runs 28.8 minutes slower in one day.
