A pendulum clock is 5 sec fast at temperature of 15 °C and 10 sec slow at a temperature of 30 °C. At what temperature does it give the correct time?
Dear student The change in time period of a pendulum and the temperature can be explained withdelta t = 1/2alpha Delta t therefore the equation will form as 5/10= T-15 / 30-T ,from where we would get T=20deg at which we would get the correct timeGood Luck
