Question

The length of an object varies with temperature according to L = 6 + 2T + 5T² The coefficient of linear expansion of this object is A) 2 + 10T B) 2/L C) 10T/L D) T/L E) (2 + 10T)/L

Quizplus · Accepted Answer

The coefficient of linear expansion is the derivative of length with respect to temperature divided by the length itself, which is (2 + 10T)/L.
