NAME ______________________________ PART A . (40%) Each question is worth 5%. In the space provided, to the left of the question number, write the letter corresponding to the best answer to the question. ___ 1. In each of the following operations, energy is expended. In some cases, a portion of the energy is stored, and can be retrieved. In which operation will the LEAST percentage of the expended energy be retrievable? A. Charging a capacitor. B. Charging a storage battery. C. Sending a current through a resistor. D. Establishing a current in an inductor. E. None of the above yield retrievable energy. ___ 2. The sketch on the left below shows a block of mass M , resting on a frictionless surface, and attached to an ideal spring of spring constant k . When set in oscillation with an amplitude of 0.10 m, the system has a period of exactly 1.0 s. When the same mass and spring are suspended from a rigid support, as shown on the right, and set in oscillation with the same amplitude, what happens to the period of oscillation? A. The period increases because the weight of the block causes the spring to stretch further. B. The period decreases because the weight of the block causes the spring to stretch further. C.
