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

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.
