For small changes in temperature, the formula for the expansion of a metal rod under a change in temperature is: g-L=al(t-T), where g is the length of the object at temperature t, and L is the length at temperature T, and a is a constant which depends on the type of metal. 1. Express g as a linear function of t. Find the slope and vertical intercept in terms of L, T, and a. Slope=, Intercept= 2. A rod is 240 cm long at 140 degrees F and made of a metal with a=10^(-8). Write an equation giving the length of this rod at temperature t (because a=10^(-8) is very small, give an exact answer: do not round expand multiplied numerical products to get rounded decimals). g= cm
