PLEASE SHOW WORK (also please reference submission history for incorrect answers)

The height of the Washington Monument is measured to be 170 m on a day when the temperature is 35.0degreeC. Assume its thermal coefficient of linear expansion is 2.5 times 10^-6/degreeC. What will its height be, in meters, on a day when the temperature falls to -10.0degreeC? -Use the formula for the expanded (or contracted) length in terms of the initial length, thermal coefficient of linear expansion, and temperature change. -Use the formula for the expanded (or contracted) length in terms of the initial length, thermal coefficient of linear expansion, and temperature change.

Explanation / Answer

Delta L/L= alpha L *DeltaT

Delta L= 170m*2.5*10^-6*45

delta L=0.019125

Then length = 170-0.019125= 169.98m
