2. Some of the most accurate pendulum clocks were 'mercury-compensated' against temperature changes. Consider a steel pendulum rod 100 cm in length and supporting a pendulum bob consisting of a glass vial containing mercury. What must be the height of the mercury in the vial so that the period of the pendulum will not vary with changes in temperature? Assume the pendulum behaves like a 'simple' pendulum. Take the coefficients of linear expansion of steel and mercury to be, respectively...

The coefficient of linear expansion of a mystery metal alloy is 1.20 x 10-5 K 1. At 20.0° C a rod made of this alloy has a length of 11.9200 m. The rod is cooled to -29.0° C. Calculate the change in length (AL) of the rod. Remember that a negative change in length means that the length decreases, and a positive change in length means that the length increases. (There must be three significant figures in your answer.) x...
