What is the law of conservation of mass? (worth 15 points)

Aregion of space in which a measurable gravitational force is indicated by the force exerted on a test mass is called

Which diagram correctly demonstrates the various forces acting on a ball moving horizontally with some speed?

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?
