I am trying to solve this question..
A pendulum clock with a pendulum made of brass is designed to keep accurate time at 23 °C. If the clock operates at 0.0°C, what is the magnitude of its error, in seconds per hour (use a minus sign to indicate slowing down)? The linear expansion coefficient of brass is 19 x 10-6 /C°.
I know that the the period of oscillation is
T= 2pi * sqrt( L /g)
and that the change in the length of the pendulum
is
-4.37E-4 m
I just don't know how to relate the two to solve
Any help is appreciated.
