Recently, the observations on the earth tide at Shiquanhe and Wushi were used to show that gravity propagates at the speed of light. Based on the brief review of general relativity and the Newtonian gravitational theory, we re-analyze the experiments and cannot reach the same conclusion ...
The force of gravity on the moon is about one-sixth that on the earth. If an object weighs 60N on the earth, its weight on the moon is ___. A. 10N B. 360N C. 60N D. 120N 相关知识点: 试题来源: 解析 A。本题考查重力的知识和英语表达。在地球上重力为 60N 的物体,在月球上重力...
解析 A 句意:火星上的重力大约是地球上的八分之三。考查名词辨析题。A. gravity重力,指地心引力B. food食物;C. quality质量,强调品质;D. weight重量。根据句意语境,可知BCD三项意思都与句意不合,故选A。结果一 题目 The ___ on Mars is about three-eighths of that on the Earth. A. gravity B. f...
On Earth,gravity keeps our feet on the ground and makes anything we drop ___ (fall) towards the ground. 答案 fall答案:fall. we drop是定语从句,修饰先行词anything,也就是说"anything we drop"这部分作make的宾语,make经常用于结构:make sb./sth.do sth.让某人或某物做某事.经过以上分析,所以后面...
