Answer to Question #187031 in Physics for Clark Banuelos

Question #187031

Compute the increase in length of 50m copper wire when its temperature changes from 12 deg C to 32 deg C. For copper, 𝝰 = 1.7 x 10^-5 /deg C.

Expert's answer

The increase in length is

"\\Delta L=L_0\\alpha \\Delta T=(50)(1.7\u00b710^{-5})(32-12)=0.017\\text{ m},"

or 1.7 cm.
