C 正确答案:C 解析:根据文章第四段中的第二句“Although the Sun is larger than the Moon.The Moon is closerto Earth and,therefore,its gravitational force is approximately 2.2 times greater.”判断可知,地球对太阳和月球的引力大小是由它们与地球之间的距离决定的。反馈...
The gravitational force of the Sun and the Moon upon Earth depends on ___. A. their distance to Earth B. the depth of the oceans C. their size D. their weight 相关知识点: 试题来源: 解析 A 答案:A 解析:分析第三段可知,太阳和月亮对地球的引力与其和地球的西南方有关。反馈...

As a rocket leaves the earth, the pull of the earth on it becomes less and less as the rocket roars out into space. If you imagine a line between the earth and the moon, there’s a point somewhere along that line, nearer to the moon than to the earth, at which the gravitational ...
When the moon rotates around the earth, its gravity has a major physical influence on a number of regions on the earth. This physical change can be seen by the tides. The tides make sea levels high and low in coastal regions. During high tide, the gravitational force of the Moon pulls ...
The start from both the low orbit of the Moon satellite and the Moon surface is considered. Characteristics of these trajectories are presented. They are compared with the usual trajectories of the direct flight. The "detour" Moon-to-Earth trajectories with initial elliptic orbit and gravitational...
