4. [-14 Points] - SERPSEWA10 27.WA.017. Consider the circuit shown in the diagram below. The battery has a voltage V = 12.0 V and the resistors have the following values. R1 = 2.15 0; R2 = 4.30 (2-, R3 = 10.75 9.; R4 = 6.45 n How much current ows through each of the four resistors? V R: R3 R4 5. [16 Points] SERPSEWA10 27.WA.006. An automobile starter motor has an equivalent resistance of 0.0460 9. and is supplied by a 12.0V battery with in 0.026041 internal resistance. (a) What is the current to the motor? A H (b) What voltage is applied to it? V H (c) What power is supplied to the motor? kW H (d) Repeat these calculations for when the battery connections are corroded and add 0.0900 0 to the circuit. (Significant problems are caused by even small amounts of unwanted resistance in lowvoltage, highcurrent applications.) 6.

Calculate the magnitude of the force on the proton. :1 7. [-11 Points] DETAILS BAUERPHYSZ 27.P.025. MY NOTES The magnitude of the magnetic force on a particle with charge 2e moving with speed v = 1.1 x 105 m/s is 3.7 x 10'18 N. What is the magnitude of the magnetic eld component perpendicular to the direction of motion of the particle? :] B. [-12 Points] DETAILS BAUERPHYS2 27.P.027. MY NOTES a, A particle with a charge of 20 pC moves along the xaxis with a speed of 41 m/s. It enters a magnetic field given by B = 0.29}? + 0.692, in teslas. Determine the magnitude and the direction of the magnetic force on the particle. magnitude C] [:1 direction counter-clockwise from the +yaxis in the yzplane
