Question

The metal of a pendulum clock has a coefficient of
expansion as 2 x10-$/K . Its period is 2s at 15°C.
If the temperature increases to 25°C, shall the
clock
(1) Show correct time
(2) Lose time
(3) Gain time
(4),First lose and then gain time​

Answer 1

Answer:

option 2.Lose time

Explanation:

as

T=2π√l/g

if temperature increases the metal will expand.

If the metal increases in lenght then the time period of the clock will also increase

cause

T is directly proportional to l

therefore time taken to complete one oscillation will increase and hence it will slow down bit by bit

And in short it will lose time.

Hope this helps.
