A satellite orbits Earth 5.00x10^2 km above its surface. What is its period? The radius of Earth is 6.38x106 m and Earth has a mass of 5.97x1024 kg. Assume (G = 6.67x10-11 N•m2/kg2). a. 94.6 h or 340560 s b. 1.43 h or 5148 s c. 1.58 h or 5682 s d. 15.7 h or 56520 s

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?
