solve the following questions ( handwritten solution only neatly and clean box final answer) thankyou!

PROBLEM # 3 An aluminum wire carrying a current has a diameter of 0.600 mm. The electric field in the wire is 0.640 V/m. What is the current carried by the wire? What is the potential difference between two points if the wires are 12.0 m apart? What is the resistance of a 12.0 m length of wire?PROBLEM #1 PROBLEM #2 What is the rate of energy conversion A silver wire 1.00 mm in diameter and dissipation in the battery, net transfers a charge of 65.0 C in 1 hr. power output if the battery has an 15.0 min. Silver contains 5.0 x 1028 emf of 12 V, a current of 2 A, electrons per cubic meter. What is resistance of 40 and internal the current in the wire? What is the resistance of 20? magnitude of the drift velocity of the electrons in the wire
