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? Answer in units of electrons/s. Your response... PALETTE
