A pendulum clock loses 24 sec a day if the temperature is `60^(@)C` and gains 8 sec a day if the temperature is `40^(@)C` .The temperature at which the clock will show correct time.

A pendulam clock loses 12s a day if the temperature is 40^@C and gains 4s a day if the temperature is 20^@C , The temperature at which the clock will show correct time, and the co-efficient of linear expansion (alpha) of the metal of the pendulam shaft are respectively:

A pendulum clock is 5 sec. Slow at a temperature 30^(@)C and 10 sec. fast at a temperature of 15^(@)C , At what temperature does it give the correct time-

A pendulum clock ( fitted with a small heavy bob that is connected with a metal rod ) is 3 seconds fast each day at a temperature of 15^(@)C and 2 seconds slow at a temperature of 30^(@)C . Find the temperature ( in ""^(@)C ) at which will show the correct time.

A perpendicular clock (fitted with a small heavy bob that is connected with a metal rod) is 5 seconds fast each day at a temperature of 15^(@)C and 10 seconds slow at a temperature of 30^(@)C . The temperature at which it is designed to give correct time, is

Day time temperature of moon is

A clock with a metallic pendulum gains 6 seconds each day when the temperature is 20^(@)C and loses 6 second when the temperature is 40^(@)C . Find the coefficient of linear expansions of the metal.
