A. The centripetal force is provided by the gravitational force between the satellite and the Earth B. The centripetal force is provided by the engine of the satellite C. The centripetal force is zero because the satellite is in a state of equilibrium D. The centripetal force is provided by...
The orbit of Compass-M1 is nearly circular, has an altitude of 21,150 km and an inclination of 55.5°.[citation needed] 参考译文:Compass-M1是一颗为信号测试、验证和频率文件而发射的试验卫星,于2007年4月14日发射。Compass-M1在北斗系统中的作用类似于GIOVE卫星在伽利略系统中的作用。Compass-M1的轨道...
一道天体物理的题,实在想不出来了,(2) The Canadian Space Agency gives you a second assignment.A satellite is in circular orbit around Mercury.It travels at a distance of 124 km above the surface of Mercury and its period of rotation is 1
apsis- The extreme point of an orbit. eccentric- First meant "not concentric" as it referred to an orbit in which the Earth was not precisely in the center or straying from a circular path; the area where two circles overlap is the eccentric. ...
In this paper, we consider the rotational motion of a gyrostat satellite in a circular Keplerian orbit around a planet. The motion is first considered to be spherical, and in a second case with an axis of symmetry.Firstly, we establish the Newton's equations and we prove that the ...

A geostationairy satellite is a satellite that, because of it's orbital position, rotates around the earth. It also does not fall into space and does not fall to the earth. It seems to be in the same position in the sky in all time. This delicate balance depends on the speed of the...

Takashi Iida, Hiromitsu Wakana, in Encyclopedia of Physical Science and Technology (Third Edition), 2003 II.B.1 Antennas Satellite antennas concentrate the satellite's transmitting power into a designated geographical region on earth and avoid interference from undesired signals transmitted from outside ...
A satellite with mass 848 kg is in a circular orbit with an orbital speed of 9640 m/s around the earth. What is the new orbital speed after friction from the earth’s upper atmosphere has done -7.50·109 J of work on the satellite? Does the speed increase or decrease? Homework Equatio...
