It may be either actual, (direct or positive.) where physical force Is put upon a man to compel him to do an act against his will, or implied, (legal or constructive.) where the relation of the parties is such that one is under subjection to the other, and is thereby constrained to do what his free will would refuse.
Related Terms. Short for low earth orbit, a satellite system used in telecommunications. LEO satellites orbit the earth between 400 and 1,000 miles above the earth's surface. LEOs are mostly used for data communication such as e-mail, paging and videoconferencing.
Depends on the Altitude of the Satellite. Most are around 90 minutes. The closer an object is to the Earth, the faster it must circle to balance the gravitational pull of the Earth. The closest satellites (~100+ km) are in in low Earth orbit (LEO); these can circle the Earth in as little as 90-100 minutes. Any lower than this and the atmosphere would quickly slow the object down so that it would fall back to Earth after relatively few orbits.
