8 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 Fig. 17-29. Rank the curves according to (a) the linear speed v of the sound source, (b) the angular speeds o of the merry-go-rounds, and (c) the radii r of the merry-go-rounds, greatest first. 2-

Question

8 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 Fig. 17-29. Rank the curves according to
(a) the linear speed v of the sound source, (b) the angular speeds o of
the merry-go-rounds, and (c) the radii r of the merry-go-rounds,
greatest first.
