Question: A loudspeaker having a diaphragm that vibrates at 9 7 0 Hz is traveling at 6 5 . 0 m / s directly toward a

A loudspeaker having a diaphragm that vibrates at 970 Hz is traveling at 65.0 m/s directly toward a pair of holes in a very large wall in a region for which the speed of sound is 344 m/s. You observe that the sound coming through the openings first cancels at 14.4 with respect to the original direction of the speaker when observed far from the wall.
Part A
How far apart are the two openings?
Part B
At what positive angle would the sound first cancel if the source stopped moving?
