Astudent is performing an experiment comparing sound and light waves. the student gathers the following data. what conclusion does the student most likely make based on this data? light waves always travel the same speed; however, the speed of sound is determined by the medium that it travels through. all sound waves always have the same energy, so the temperature of the medium does not affect wave speed. light needs to vibrate particles, so it travels fastest in tightly packed solids, while sound does not need a medium, so it travels fastest in a gas. tightly packed particles in solids slow down the light waves; however, sound waves make particles bounce into each other, so they travel faster in solids.

Two resistors r1 and r2 may be connected either in series or parallel across an ideal battery with emf Îľ. we desire the rate of energy dissipation of the parallel combination to be 8.75 times that of the series combination. if r1 = 105 Ď, what are the (a) smaller and (b) larger of the two values of r2 that result in that dissipation rate?
