A small object carrying a charge of 3.47 µC experiences an electric force of 7.22 × 10–2 N when placed at a distance, d, from a second, identically charged object. The value of d is __________ m. (Record your three-digit answer in the numerical-response section on the answer sheet.) Numerical Response 8. The number of excess electrons on a ball that has a charge of –3.60 × 10–17 C, expressed in scientific notation, is a.bc × 10d. The values of a, b, c, and d are _____ , _____ , _____ , and _____ . (Record all four digits of your answer in the numerical-response section on the answer sheet.) 18. An electron accelerates from rest across the gap between charged parallel plates and reaches a final speed of v. If the potential difference across the plates is tripled, the final speed of an electron accelerating from rest across the gap will be A. B. C. D. 19. 1v 3 1v 3 3v 9v X-rays are produced by A. B. C. D. an alternating current of about 1018 Hz firing gamma rays at a tungsten electrode varying the speed of electrons in a magnetic field collisions between high-speed electrons and a metal target 12 Use the following information to answer the next question. In 1996, the space shuttle Columbia attempted to drag a conducting tether through Earth’s magnetic field. The tether was 2.07 × 104 m long. The average magnitude of Earth’s magnetic field perpendicular to the tether was 9.02 × 10–6 T. The speed of the shuttle and tether was 8.00 × 103 m/s, relative to Earth’s magnetic field. Numerical Response 9. The electric potential difference generated across the ends of the tether, expressed in scientific notation, was a.bc × 10d V. The values of a, b, c, and d are _____ , _____ , _____ , and _____ . (Record all four digits of your answer in the numerical-response section on the answer sheet.) Use the following information to answer the next question. Series Circuit R V 120 V 20. A In the circuit above, the voltmeter reads 90 V and the ammeter reads 1.5 A. The value of the resistor, R, will be A. B. C...
