Which of the following quantities are scalar quantities? A. B. C. D. Kinetic energy and potential energy Kinetic energy and momentum Potential energy and force Momentum and force Use the following information to answer the next two questions. A “full draw” is the maximum distance that an archer can pull back an arrow. Using the “recurve bow” shown below, a particular archer requires an average force of 130 N to pull a full draw of 70.0 cm. Arrow String Arrow String 30.0 cm 100.0 cm 2. The maximum speed of a 20.6 g arrow leaving this bow from a full draw is A. B. C. D. 66.5 m/s 94.0 m/s 4.42 × 103 m/s 8.83 × 103 m/s Use your recorded answer for Multiple Choice 2 to answer Numerical Response 1.* Numerical Response 1. When the archer releases the arrow from a full draw, the magnitude of the impulse that the bow gives to the arrow is __________ N.s. (Record your three-digit answer in the numerical-response section on the answer sheet.) *You can receive marks for this question even if the previous question was answered incorrectly. 1 Use the following information to answer the next question. Electric Field Lines Near Two Charged Spheres X 3. Y The types of charge present on X and Y are, respectively, A. B. C. D. negative and negative negative and positive positive and negative positive and positive Use the following information to answer the next four questions. Charles Augustin de Coulomb performed a series of investigations on the quantitative nature of electrical forces. He was able to determine the effect of both distance and magnitude of charge on the electrostatic force between two charged metal spheres. 4. In order to determine the relationship between force and distance, Coulomb needed to A. B. C. D. keep the magnitude of one charge constant keep the magnitude of both charges constant keep the distance between the charges constant vary the magnitude of one charge while varying distance between the charges 2 5. Which of the following graphs represents the relationship that Coulomb determined between force and the distance between two charged metal spheres? A. B. F F r r C. D. F F r 6. r Coulomb started with two identically charged spheres separated by a distance r. 2 The force between the spheres was F. If he changed the separation to r , then 3 the force between the spheres would have become A. 4F 9 B. 2F 3 C. 3F 2 D. 9F 4 3 7. Coulomb again separated the identically charged spheres by distance r. The force between the spheres was F. Coulomb touched one of the spheres with a third, identical neutral sphere. The third sphere was then moved far away from the other spheres. If he then measured the force between the original spheres, the new force between the spheres would have been A. B. 1F 4 C. 2F D. 8. 1F 2 4F A point charge of magnitude 6.9 × 10–5 C produces an electric field of 1.0 × 103 N/C at point P. The distance from P to the charge is A. B. C.
