[MI02 18.Q.01.] 8/10 points | 4/4 submissions Last Response | Show Details All Responses Notes A circuit is constructed from two batteries and two wires, as shown in the diagram below. Each battery has an emf of 1.4 volts. Each wire is 27 cm long, and has a diameter of 0.0007 meters. The wires are made of a metal which has 7e+28 mobile electrons per cubic meter; the electron mobility is 2e-05 (m/s)/(V/m). A steady current runs through the circuit. The locations marked by "x" and labeled by a letter are in the interior of the wire. Which of these statements about the electric field in the interior of the wires, at the locations marked by "x"s, are true? Check all that apply. [_] [_] The magnitude of the electric field at location G is larger than the magnitude of the electric field at location F . [x] [x] At every marked location the magnitude of the electric field is the same. [x] [x] At location D the electric field points to the right . Which of the following equations is a correct energy conservation (round-trip potential
