Harmonic Oscillation 1. Aluminum has a density of 2.7 g/cm 3 and a molar mass of 27 g/mol and copper has a density of 8.9 g/cm 3 and a molar mass of 64 g/mol. Which atom has a larger diameter, an aluminum atom or a copper atom? (a) aluminum (b) copper (c) every atom has the same diameter regardless of what element it is 2. You have two wires, a copper wire of radius 1 × 10 -4 m and a copper wire of radius 1 × 10 -3 m. You hang each wire from a support, and you hang 1 kg from the end of each of the wires. Which wire will stretch the most from its original length? (a) the smaller radius wire (b) the larger radius wire (c) they will both stretch the same amount 3. Suppose that in lab you measure the period T of a 0.5 kg object attached to a spring. If you replace the spring with one that has twice the spring constant, the period will be (a) 2T (b) (1/2)T (c)sqrt(2)T (d) (1/sqrt(2))T (e) T 4. You watch a physics student’s experiment and notice that the object attached to her spring travels from its lowest position to its highest position in about 1 second. What is the period of oscillation? (a) 0.5 s
