(8%) Problem 12: Two eagles fly directly toward one another, the first at 15.5 m/s and the second at 17.5 m/s. Both screech, the first one emitting a frequency of 3050 Hz and the second one emitting a frequency of 3550 Hz. ▷ 50% Part (a) What frequency of sound, in hertz, does the first eagle hear from the second if the speed of sound is 330 m/s?
