Keeping time in Gold Country at the Jackson Rusty Rosebud
[1]
The Rusty Rosebud Antique Boutique in Jackson sells classic antique pendulum clocks. Ideally, the brass pendulum takes precisely two seconds to swing to-and-fro.
Pat, the proprietress, is aware her clocks are not compensated for temperature changes. The average shop temperature for the entire month of January is a brisk 18° C. Her best clock, the Metronome, keeps perfect time for the entire month of January.
However, the Metronome loses a total of two minutes during the month of July. Given her climate consciousness, Pat does not air condition the Rusty Rosebud.
The brass pendulum rod has a coefficient of linear thermal expansion α.
Given α = 7.467311836 x 10 − 6 m/m° C, find the average store temperature for July.
