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 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 clock , with a brass pendulum, keeps correct time at 20^(@)C , but loses 8.212 s per day , when the temperature rises to 30^(@)C . Calculate the coefficient of linear expansion of brass.

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) 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 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
