Thermal Pendulum Clock. One problem that early pendulum clocks faced was inconsistencies due to thermal expansion. Consider a long pendulum clock of thermal expansion coefficient a = 30 x 10-K-. Its length is perfectly set such that it makes half a period in 1s at 15 C. A change in temperature, however, causes this length to change by a factor of eAT, Suppose this pendulum elock is kept at 40°C for exactly 1 week. After exactly 1 week, how many seconds earlier (positive) or later (negative) would the clock's midnight be compared to the true midnight?
