Question

Suppose that at room temperature, a certain aluminum bar is 1.0000 m long. The bar gets longer when its temperature is raised. The length l of the bar obeys the following relation: l=1.0000+2.4

Suppose that at room temperature, a certain aluminum bar is 1.0000 m long. The bar gets longer when its temperature is raised. The length l of the bar obeys the following relation: l=1.0000+2.4 times 10^-5 T where T is the number of degrees Celsius above room temperature. What is the change of the bar's length if the temperature is raised to 17.3 ? C above room temperature? Express your answer in meters to two significant figures. I only have 1 attempt left but mastering physics said that my answer of 4.1 * 10^-4 M was very close and to check the number of rounding and significant digits in my final answer. I can not figure out why thats wrong thanks for any help.

Explanation / Answer

l=1.0000+2.4
