Two eagles f|y directly toward one another, the first at 15.0 m/s and the second at 15.2 m/s. Both screech, the first emitting a frequency of 3543 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.) 3800 )( I'St How is the frequency of the observer related to the frequency of the source when both the source and observer are moving? If eagle 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? Hz 535\"d 3880 g; Hz eagle If two successive resonant frequencies for an open ended organ pipe (open at both ends) are 195 Hz and 234 Hzr and the speed of sound in air is 343 m/s, determine the following. (a) frequency of the fundamental 75 x For a tube open at both ends, how is the length of the tube related to the resonant wavelengths? How are the speed, wavelength and frequency of sound related? How are two successive resonant frequencies related to the fundamental frequency? Hz (b) length of the pipe 228 J; For an open tube, how is the fundamental frequency related to the speed of sound in air and the length of the tube? m
