Unformatted text preview: 1 pt The figure shows a circuit with three resistors. The emf of the battery is 12 volts. Calculate the current in resistor R 1 . Data: R 1 = 1.80 ; R 2 = 3.80 ; R 3 = 5.40 . (in A ) 1 . A 1.62 B 1.83 C 2.06 D 2.33 E 2.63 F 2.98 G 3.36 H 3.80 1 pt The figure shows a circuit with two resistors. The emf of the DC power supply is 80 volts. Calculate the power dissipated in resistor R 2 . Data: R 1 = 12.0 ; R 2 = 48.1 . (in W ) 2 . A 33.2 B 38.9 C 45.5 D 53.2 E 62.3 F 72.8 G 85.2 H 99.7 1 pt The electron will be deected as it moves in the magnetic field. The direction of deection is 3 . A dependent on the spin direction. B out of the page. C into the page. D up toward N. E down toward S. F none of the above. 1 pt The figure shows a proton entering a D-shaped region in which the magnetic field B points into the page. The proton velocity is perpendicular to B and the speed is 2 . 00 × 10 7 m/s. The distance d in the figure is d = 0.55 m. Calculate the strength of the magnetic field....
