The heating element of a simple heater consists of a 1.9-m-long, 0.65-mm-diameter nichrome wire. When plugged into a 120 V outlet, the heater draws 7.0 A of current when hot.

(part A) What is the wire's resistance when it is hot? (in ohms)

(part B) Use your answer to part A to calculate the resistivity of nichrome in this situation. (in ohms x m)
