Questions
Why do we use Invar material for the pendulum of good clocks?
a
Invar is an alloy which has a very small coefficient of linear thermal expansion. Hence, the time period does change appreciably with the change of temperature.
b
Invar is an alloy which has a very small coefficient of linear thermal expansion. Hence, the time period does not change appreciably with the change of temperature.
c
Invar is an alloy which has a very small coefficient of linear thermal expansion. Hence, the time period becomes double with the change of temperature.
d
Invar is an alloy which has a very small coefficient of linear thermal expansion. Hence, the time period becomes half with the change of temperature.
detailed solution
Correct option is B
Invar is an alloy which has a very small coefficient of linear thermal expansion. Hence, the time period does not change appreciably with the change of temperature.Talk to our academic expert!
