A pendulum clock runs fast by `5` seconds per day at `20^(0)c` and goes slow by `10` seconds per day at `35^(0)C`. It shows correct time at a temperature of

A clock with a metallic pendulum al 15°C runs faster by 5 seconds each day and at 30°C, runs slow by 10 seconds. Find the coefficient of linear expansion of the metal (nearly in 10^(-6) //^(@) C)

A wall clock regulated by a seconds pendulum goes slow by 20 second per day. How many oscillation are performed by the faulty pendulum per day ?

A pendulum clock is 5 seconds fast at a temperature of 15^(@)C and 10 seconds slow at a temperature of 30^(@)C . The temperature at which it gives the correct time is

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

(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.
