C. 1.2 V D. 0.48 V 9. A 10.0-Q resistor and a 20.0-Q resistor are connected in series with a potentiometer and a 9.0-V battery. What should the potentiometer be set at for a total equivalent resistance of 50.0 Q in this circuit? A. 10 0 B. 20 Q C. 30 0 D. 50 0 10. Thomson created the electron beam by applying a large between the cathode and anode. A. vacuum B. pressure difference C. potential difference D. space differenceD. size of the magnet 14. A nail that touches a magnet will A. melt. B. generate an electric current. C. become polarized. D. demagnetize the magnet. 15. A hair dryer operating from 120 V has two settings, hot and warm. In which setting is the resistance likely to be smaller, why? A. The hot setting draws more power, so the fixed voltage current is larger, Therefore, the resistance is smaller. B. The warm setting draws more power, so the fixed voltage current is larger. Therefore, the resistance is smaller. C. The hot setting draws more power, so the fixed voltage current is smaller. Therefore, the resistance is smaller. D. The warm setting draws more power, so the fixed voltage current is smaller. Therefore, the resistance is smaller.invain hunter physics 2 test 2- > M (no subject) - evanhunter29x + docs.google.com/document/d/1pvp_DPewJ_ Hockeytv M emall T School School N Netflix h Hull evan hunter physics 2 tes... # 0 3 File Edit View Insert Format Tools Extensh A 100%- Normal init.
