C 选项 “The Moon's gravity”(月球的引力),月球引力主要影响其周围的物体,比如对地球海洋产生一定的潮汐作用等,但并非是减缓月球自转的原因,所以 C 选项错误。而地球的引力(The Earth's gravity)通过长期的潮汐力作用,逐渐减缓了月球的自转速度,所以正确答案是 B。反馈 收藏 ...
选项 B“Objects would fall to the earth”是物体落向地球,与假设不符;选项 C“Objects would stay on the moon's surface”在没有重力的情况下物体不会仅仅停留在月球表面;选项 D“Objects would disappear”物体消失与假设无关。选项 A“Objects would float on the moon”符合没有重力时物体漂浮的情况,...
Answer to: The force of gravity on the Moon is said to be 1/6th of that on the Earth . What would be the mass of 12kg weighed on the surface of the...
he geometry of space will also determine the ultimate fate of the universe. In a closed universe, where the density of matter is high enough to exceed the critical density, gravity will eventually halt cosmic expansion. Instead, the universe will begin to contract, like rewinding the clock, an...
In fact the moon is the Earth’s satellite(卫星).Many planets have a satellite,and some have many.Our moon travels around the Earth once a month.It’s much smaller than the Earth and gravity(引力)pulls it. In most nights the moon is the brightest thing in the sky.This is because it...
[听力原文]Most waves are caused by winds, though earthquakes on the ocean bed can also cause them, and tides are caused by the effect of the gravity of the moon on the earth and also, although to a lesser extent, the sun’s gravity. One bulge of water is drawn upon the side of th...
formThe Moon. The Moon is currently moving about three centimetres a year away from us and will not hit us unless there are some super outside forces to change its direction. Eventually, The Moon will break free from Earth'sgravityand be free floating. It will not happen in our lifetime...
A standard lunar day is equivalent to 29.53 Earth days. Due to the Moon's reduced gravity, a clock gains about 56 microseconds compared to 24 hours on Earth. The idea of space explorers using an agreed-upon time has been floated around for years, with the European Space Agency recently ex...
a我们是穿梭在银河的火箭队 We are the shuttle in the Milky Way Rocket[translate] aThe American space agency Nasa is about to put two new satellites into orbit around the Moon to map its gravity. Scientists expect the data to reveal what exactly lies beneath the Moon's surface, shedding new...
Others may recognise it from Enigma’s 1999 song ‘Gravity of Love’, though those associating it withThe Omenare victims of popular misconception – it never in fact appears in the 1976 thriller’s score. What is Carmina Burana actually about?
