This quantity, which is highest in solids and lowest in gases, appears in the denominator of the formula for calculating the Mach number.
Maurice Ewing discovered that this quantity reaches a minimum value in the ocean at the SOFAR layer. For an ideal gas, this quantity equals the square root of the quantity adiabatic constant times gas constant times temperature divided by molecular mass. For a solid, this quantity equals the square root of the quantity Young's modulus divided by density. This quantity, which is highest in solids and lowest in gases, appears in the denominator of the formula for calculating the Mach number. Objects moving through the air faster than this quantity can produce a sonic boom. For 10 points, name this quantity equal to about 343 meters per second in air.
