A clock has a long pendulum made of brass. Due to a temperature change of `20^(@)C` the time period of oscillation of the pendulum is found to change by 0.02%.The coefficient of linear expansion of brass 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.

What is the percentage change in the time period, if the length of simple pendulum increases by 3% .

A clock with an iron pendulum keeps correct time at 20^(@)C . How much time will it lose or gain in a day if the temperature changes to 40^(@)C . Thermal coefficient of liner expansion alpha = 0.000012 per^(@)C .

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)

If length of simple pendulum is increased by 6% then percentage change in the time-period will be
