Communication satellites are placed in a geosynchronous orbit, that is, in a circular orbit such that they complete one full revolution about the earth in one sidereal day (23.394 h), and thus appear stationary with respect to the ground. Determine
(a) The altitude of these satellites above the surface of the earth,
(b) The velocity with which they describe their orbit. Give the answers in both SI and U.S. customary units.
