A friend rides, in turn, the rims of three fast merry-go-rounds while holding a sound source that emits isotropically at a certain frequency. You stand far from each merry-go-round. The frequency you hear for each of your friend's three rides varies as the merry-go-round rotates. The variations in frequency for the three rides are given by the three curves in the figure. Rank the curves according to the angular speeds w of the merry-go-rounds, least first. radius of a herry-90-round. time to
