G=Gravitational force

M=Mass of the earth

R=Radius of earth

h=height of satellite above the earth surface

R+h=Radius of the orbit

Answer 2

Answer:

Critical velocity is the speed and direction at which the flow of a liquid through a tube changes from smooth, or "laminar," to turbulent. Calculating critical velocity depends on multiple variables, but it is the Reynolds number that characterizes the flow of the liquid through a tube as either laminar or turbulent.
