Question

The height of the Washington Monument is measured to be 170 m on a day when the temperature is 35.0 C . Assume it's thermal coefficient of linear expansion is 2.5 * 10^-6 C . What will its height be in meters on a day when the temperature falls to -10.0 C ? The height of the Washington Monument is measured to be 170 m on a day when the temperature is 35.0 C . Assume it's thermal coefficient of linear expansion is 2.5 * 10^-6 C . What will its height be in meters on a day when the temperature falls to -10.0 C ?

Explanation / Answer

L = Lo(1 + T) = 170{1 + [(2.5 * 10-6) * (-10 - 35)]} = 169.981 m
