(III) A physics professor wants to demonstrate the large sizeof the henry unit. On the outside of a 12-cm-diameter plastichollow tube, she wants to wind an air-filled solenoid withself-inductance of 1.0 H using copper wire with a 0.81-mmdiameter. The solenoid is to be tightly wound with each turntouching its neighbor (the wire has a thin insulating layeron its surface so the neighboring turns are not in electricalcontact). How long will the plastic tube need to be and howmany kilometers of copper wire will be required? What willbe the resistance of this solenoid?
