For 10 points, name this property that is about 340 meters per second at sea level and is equivalent to a velocity of Mach 1.
This property can be calculated for a medium using an equation that takes a square root of the medium's ratio of specific heats, gas constant, and absolute temperature. When an object reaches this value for a medium, that object can experience choked flow and create a vapor cone. One equation involving this value places it in the denominator under the (*) velocity of an object, with the outcome of that equation being named for an Austrian physicist.
