3. [40 points) In questions (a) through (e) show all your calculations and units as applicable. You will be assessed both on your answers and your explanations of how you got them. (a) What is the wavelength of a sound wave traveling through the air at sea level that has a frequency of Whertz? (b) How many joules of heat are required to change X grams of solid ice with a temperature of 260 Kelvin into that many grams of liquid water with a temperature of 300 Kelvin? [For this question, you may use 273 Kelvin as the melting point of ice.] (c) A vehicle passes you traveling at Y meters per second while you are standing still. If its engine makes sound with a frequency of 115 hertz, at what frequency will you hear that sound? (d) If a pendulum on Earth with a string length of Z meters is swinging back and forth in simple harmonic motion, then what is its period of oscillation? (e) A physician is pushing - that is, injecting - medicine into a patient's arm with a hypodermic syringe. If the top (thumb) part has an area W times greater than the bottom (needle) part, how much force will be delivered to the patient's skin if the physician pushes with Z newtons of force?
