1.	A clock whose pendulum makes one complete oscillation in two seconds is correct at 25^(@)C. The pendulum shaft is of steel and thin. What is the fractional change in the length of the shaft when it is heated to 35^(@)C? How many seconds per day will the clock gain or lose at 35^(@)C? alpha=11xx10^(-6)(C^(@))^(-1).
Answer» Solution :LOSS or gain intime period for DAY is `RARR 5.5xx10^(-5)xx86400=4.752sec`.
