A pendulum clock having copper rod keeos correct time at `20^0 C`. It gains 15 seconds per day if cooled to `0^C`. Calculate the coefficient of linear expansion of copper.

(a) A pendulum clock consists of an iron rod connected to a small, heavy bob. If it is designed to keep correct time at 20^(@)C , how fast or slow will it go in 24 hours at 50^(@)C ? alpha_(iron)=1.2xx10^(-5)//^(@)C . (b) A pendulum clock having copper rod keeps correct time at 20^(@)C . It gains 15 seconds per day if cooled to 0^(@)C . Find the coefficient the of linear expansion of copper.

A clock with a metal pendulum beating sconds keeps correct time at 0^(@)C . If it loses 10 second a day at 20^(@)C , the coefficient of linear expansion of metal of pendulum is

A clock with a metal pendulum beating seconds keeps correct time at 0^(@)C. If it loses 12.5 s a day at 25^(@)C the coefficient of linear expansion of metal pendulum is

A pendulum clock shows correct time at 0^(@)C . On a summer day

A pendulum clock shows correct time at 0^(@)C . At a higher temperature the clock.

A pendulum clock gives correct time at 20^° C. How many seconds will it lose per day at 40^° C? (alpha = 5 xx 10^-6 /°C)

A clock which keeps correct time at 25^(@)C has a pendulum made of a metal. The temperature falls to 0^(@)C . If thecoefficient oflinear expansion of the metal is 1.9xx10^(-5) per .^(@)C , then number of second the clock gains per day is

The volume of a solid decreases by 0.6% when it is cooled through 50^(@)C . Its coefficient of linear expansion is

A clock with an iron pendulum keeps correct time at 15^(@)C . If the room temperature rises to 20^(@)C , the error in sconds per day will be (coefficient of linear expansion for iron is 0.000012//^(@)C)
