Question

why does an ordinary clock lose time in summer ?

Answer 1

A pendulum clock, you mean?

Answer 2

yes !

Answer 3

What's the formula for the period of pendulum?

Answer 4

It is
\[ T = 2 \pi \sqrt{\frac{L}{g}} \] where \( L \) is the length of the pendulum. Now, in the summer, \( T \) increases. Why?

Answer 5

the question has nothing to do with that ,,,,,give the answer ?

Answer 6

Yes it does. It has everything to do with the period of pendulum.

Answer 7

If the period \( T \) increases, then either \( L \) increases or \( g \) decreases in the summer.

Now one of those is impossible.

Answer 8

give the answer ?

Answer 9

g is always constant. Hence L increases. Now why would L increase in summer?

Answer 10

@MugeesULkaisar , we don't just hand out answers here. It's much better to think the problem through. I am leading you to the answer. We're almost there. You shouldn't give up so easily.

Answer 11

In a clock, the pendulum is typically made of metal. Now why would L increase in summer? Why would a piece of metal expand?

Answer 12

yes very good u r getting closer to the answer , com one !

Answer 13

Don't patronize me. I have connected 3 out of the 4 dots. You can connect the last one yourself.

Answer 14

it is simple, u almost answered it ,
in summer due to high temperature the length of pendulum increases due to which it's time period also increses , hence loses time in summer.
