SIu C phenomenon is f | fo, where %3D c + v fis the observed frequency (pitch) of the sound, in Hertz c is the speed of sound, in miles per hour (about 761 miles per hour) v is the speed of the sound source, in this case the car, in miles per hour fo is the frequency of the sound when stationary Using a spectrum analyzer, we could determine the observed frequency when the car was driving towards us was 270 Hz and the frequency while driving away was 240 Hz, suggesting a stationary frequency of 255 Hz. Use this information and the equation to estimate the speed of the car in miles/hour. Round your answer to one decimal place. mi/hr Question Help: DPost to forum Submit Question esc -> Search or type # % 1 2 3 4 5 6
