Slader "consider a wing in a high-speed wind tunnel. at a point on the wing, the velocity is 850 ft/s. if the test-section flow is at a velocity of 780 ft/s, with a pressure and temperature of 1 atm and 505°r, respectively, calculate the pressure coefficient at the point."

Your answer is c. explanation: plasma  is the fourth state of matter, derived from the gaseous state of matter.  plasma  can contain free  electrons  and/or  ions. while  plasma is never neutral, it can either be positively or negatively charged.  gases, however, are electrically neutral.
