Two sound waves, from two different sources with the same frequency, 500 Hz, travel in the same direction at 340 m/s. The sources are in phase. What is the magnitude of the phase difference of the waves at a point that is 3.68 m from one source and 5.79 m from the other

Agas initially at p1 = 1 bar and occupying a volume of 0.5 liter is compressed within a piston–cylinder assembly to a final pressure p2 = 4 bar. (a) if the relationship between pressure and volume during the compression is pv = constant, determine the volume, in liters, at a pressure of 3 bar. (b) repeat for a linear pressure–volume relationship between the same end states. reference
