5. The battery A circuit constructed from two batteries and two wires, as shown in the Figure be- low. Each battery has an emf of 1.3 V. Each wire is 20 cm long and has a diame- ter of 0.0007 In. The wires are made of a metal that has 7 x 1028 electron/1n3 mobile electrons per cubic meter; the electron mo- bility is 5 x105 (m/s)/(V/m). A steady current runs through the circuit. The loca+ tions marked by \"x" and labeled by a letter are in the interior of the wire. Battery 1 Ba! [cry 2 Figurr How many electrons per second enter the positive end of the battery 2?

PALETTE + + 14 12 +4 3 Figure Which of the following statements are true? 1 At location 3 inside the wire the electric field points to the right. 2 The electric field is zero at all locations inside the metal wire. 3 At location 3, the electric field points to the left. 4 The magnitude of the electric field inside the wire is the same at all locations. 5 Mobile electrons inside the wire push each other through the wire. 6 The nonzero electric field inside the wire is created by the moving electrons in the wire. 7 The electric field is parallel to the wire at every location within the wire. 8 The nonzero electric field inside the wire is created by excess charges on the surface of the wire and by the mechanical battery. Your answer should be a list of numbers corresponding to the correct statements, with the numbers separated by commas3. PotentialDifMI19x012 part 1 of 2 Your response...
