Calculate the change in length of a concrete sidewalk (coefficient of linear expansion for concrete is 12 * 10-6 / oc) that is 50 meters that undergoes a temperature change of 25 oc. 0.15 0.015 0.00015

The correct answer is 0.015 meters.

Explanation:

We know that the change in length of a material on account of temperature change is given by

where

is the initial Length

is the coefficient of linear thermal expansion

is the change in temperature.

Applying values we get
