SOLUTION: The length l(T)of a bar depends on the temperature T, according to the law l(T)=l_o*e^(∝T), where l_o is the length of the bar when T=0 and ∝ is a positive constant.

Question 736229: The length l(T)of a bar depends on the temperature T, according to the law
l(T)=l_o*e^(∝T), where l_o is the length of the bar when T=0 and ∝ is a positive constant. Calculate the percentage change in length when T increases from T=10 to T=80 and ∝=0.001
