Question

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

Quizplus · Accepted Answer

The given expression is in the form of (2 + 10T)/L, where 2 is the constant term and 10T is the linear term. The coefficient of linear expansion is the linear term, which is 10T, divided by the original length L. Therefore, the coefficient of linear expansion is (2 + 10T)/L, which is given by choice E.
