A convergent–divergent nozzle through which air flows is designed to generate Mach 2.2. The supply reservoir pressure is 2.2 MPa and the flow is discharged into ambient air at a pressure of 101 kPa. Under these conditions, the nozzle will be underexpanded, and as a result, expansion waves will exist at the nozzle exit. Find the flow direction just downstream of the exit plane expansion waves under these conditions. What effect does the presence of the expansion waves have on the net axial thrust produced by the nozzle?

Did the proton move into a region of higher potential or lower potential? did the proton move into a region of higher potential or lower potential? because the proton is a negative charge and it accelerates as it travels, it must be moving from a region of higher potential to a region of lower potential.because the proton is a negative charge and it accelerates as it travels, it must be moving from a region of lower potential to a region of higher potential.because the proton is a positive charge and it slows down as it travels, it must be moving from a region of higher potential to a region of lower potential.because the proton is a positive charge and it slows down as it travels, it must be moving from a region of lower potential to a region of higher potential.request answerpart bwhat was the potential difference that stopped the proton? express your answer with the appropriate units.î”v î” v = nothingnothingrequest answerpart cwhat was the initial kinetic energy of the proton, in electron volts? express your answer in electron volts.ki k i = nothing ev request answerprovide feedback
