Two eagles fly directly toward one another, the first at 15.0 m/s and the second at 24.7 m/s. Both screech, the first emitting a frequency of 3843 Hz and the other one of 3800 Hz. What frequencies do they receive if the speed of sound is 330 m/s? (Enter your answers to at least the nearest 10 Hz.) first eagle second eagle How is the frequency of the observer related to the frequency of the source when both the source and observer are moving? If the source moves toward the observer, should the frequency heard by the observer increase or decrease? If the observer moves toward the source, should the frequency heard by the observer increase or decrease?
