Expansion during heating
A pendulum clock (fitted with a small heavy bob that is connected with a metal rod) is $5\, seconds$ fast each day at a temperature of $15\,^oC$ and $10\,seconds$ slow at a temperature of $30\,^oC$. The temperature at which it is designed to give correct time, is ........ $^oC$
Suppose there is a hole in a copper plate. On heating the plate, diameter of hole, would
A circular disc is shown. On heating, $d_1$ increases by $0.3\%$ , then $d_2$ will
What will happen if a rod is tied with fixed supports rigidly at both ends and temperature is increased ?
