An engineer is conducting a test for the normal shockwave in air. He observed that M₂ decreases as increasing M₁, which makes sense. At the maximum possible M₁, his calculation shows that the Mach number after the shockwave M₂=0.25. Based on what you learned about normal shockwaves, the result for M₂ is O incorrect. O incorrect if the temperature is very low. O correct. correct at very high temperature.

Question
An engineer is conducting a test for the normal shockwave in air. He observed that M₂
decreases as increasing M₁, which makes sense. At the maximum possible M₁, his
calculation shows that the Mach number after the shockwave M₂-0.25. Based on what
you learned about normal shockwaves, the result for M₂ is
O incorrect.
O incorrect if the temperature is very low.
O correct.
correct at very high temperature.
