(a) Using the data in Figure, determine the values of ?0 and a from Equation 18.10 for pure copper. Take the temperature T to be in degrees Celsius.

(b) Determine the value of A in Equation 18.11 for nickel as an impurity in copper, using the data in Figure.

(c) Using the results of parts (a) and (b), estimate the electrical resistivity of copper containing 1.75 at% Ni at 100째C.
