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 air resistance 相关知识点: 试题来源: 解析 A。解析:在卫星绕地球做圆周运动时,根据圆周运动的力学...
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

2. What causes friction for a satellite in circular orbit? The main source of friction for a satellite in circular orbit is the Earth's atmosphere. As the satellite moves through the atmosphere, it experiences air resistance which causes friction. 3. Can the effects of friction be completely ...
The multibody dynamics of a satellite in circular orbit, modeled as a central body with two hinge-connected deployable solar panel arrays, is investigated. Typically, the solar panel arrays are deployed in orbit using preloaded torsional springs at the hinges in a near symmetrical accordion manner...

After the satellite has reached the final altitude, another rocket engine fires and gives the satellite a circular orbit. All rocket-engine burns occur at a precise moment and last for a precise amount of time so that the satellite achieves its proper position in space....
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...

A low earth orbit (LEO) satellite is in an approximately circular orbit 300 km abowe the surface of the Earth. If the ground station tracks the satellite when it is within a 45° central angle above the tracking antenna (directly overhead), how many kilometers does the satellite cover dur...
