Asource emits sound uniformly in all directions. there are no reflections of the sound. at a distance of 12 m from the source, the intensity of the sound is 5.0 × 10−3 w/m2. what is the total sound power p emitted by the source?

An important dimensionless parameter concerned with very high-speed flow is the mach number, defined as v/c, where v is the speed of the object such as an airplane or projectile, and c is the speed of sound in the fluid surrounding the object. for a projectile traveling at 1170 mph through air at 50 ˚f and standard atmospheric pressure, what is the value of the mach number?
