Two speakers are on top of two cars as in figure a emitting a frequency of 900Hz in phase. A listener is located in point P, 1m above the horizontal line. In figure a the cars and the listener are not moving. The cars are located at 6m distance and the horizontal line is right in the middle. Determine whether destructive or constructive interference is happening in point P. In figure b, the listener moves on the horizontal line on a car. The listener in his own car and the other two cars are moving toward each other (consider both cars as one source of sound). The cars are moving at 10m/s, calculate the speed of the listener if the frequency heard by the listener is 1,050Hz. You must type your numerical answers below and send a pic of your work. e in frequency is 75Hz.
