The five resistors shown below have the lengths and cross-sectional areas indicated and are made of material with the same resistivity. Which resistor has the least resistance? 41. Two circular coils are situated perpendicular to the z-axis as shown above. There is a current in the primary coil. All of the following procedures will induce a current in the secondary coil EXCEPT (A) rotating the secondary coil about the z-axis (B) rotating the secondary coil about a diameter (C) moving the secondary coil closer to the primary coil (D) varying the current in the primary coil (E) decreasing the cross-sectional area of the secondary coil 42. A uniform rope of weight 50 newtons hangs from a hook as shown above. A box of weight 100 newtons hangs from the rope. What is the tension in the rope? (A) 50 N throughout the rope (B) 75 N throughout the rope (C) 100 N throughout the rope (D) 150 N throughout the rope (E) It varies from 100 N at the bottom of the rope to 150 N at the top. 1988 AP Physics Multiple choice test Copyright © 1988 by College Entrance Examination Board.

To weigh a fish a person hangs a tackle box of mass 3.5 kilograms and a cooler of mass 5 kilograms from the ends of a uniform rigid pole that is suspended by a rope attached to its center. The system balances when the fish hangs at a point 1/4 of the rod’s length from the tackle box. What is the mass of the fish? (A) 1.5 kg (B) 2 kg (C) 3 kg (D) 6 kg (E) 6.5 kg 44. An object swings on the end of a cord as a simple pendulum with period T. Another object oscillates up and down on the end of a vertical spring. also with period T. If the masses of both objects are doubled. what are the new values for the Periods? Pendulum Mass on Spring (A) T 2 T 2 (B) T T 2 (C) T T (D) T 2 T (E) T 2 T 2 45. A proton collides with a nucleus of 7 14 N . If this collision produces a nucleus of 6 11 C and one other particle, that particle is (A) a proton (B) a neutron (C) a deuteron (D) an x particle (E) a E particle 46. The scattering of alpha particles by a thin gold foil was measured by Geiger and Marsden. The Rutherford model of the atom was proposed in order to explain why (A) more particles scattered through angles greater than 90° than through angles less than 90° (B) the fraction of particles scattered through large angles was too large to be explained by previous models of the atom (C) no particles passed through the foil undeflected (D) the most common scattering angle was about 90° (E) the most common scattering angle was about 180° 47. A wire in the plane of the page carries a current directed toward the top of the page as shown above.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
