All waves travel at different speeds in different media. We studied how the speed of light and sound changed in the different states of matter. Tell whether each statement relates to sound or light. Group of answer choices Travels fastest in solids, slower in liquids and slowest in a gas. light (and all EM waves) Travels slowest in solids, faster in liquids and even faster in a gas. sound travels about 340 m/s in air light (and all EM waves) travels at 3 x 10^8 m/s sound Cannot travel through a vacuum. sound Travel the fastest in a vacuum. light (and all EM waves)

Suppose a wheel with a tire mounted on it is rotating at the constant rate of 2.15 times a second. a tack is stuck in the tire at a distance of 0.373 m from the rotation axis. noting that for every rotation the tack travels one circumference (a) find the tack's tangential speed. (b) what is the tacks radial acceleration?
