解析 D 考查定语从句引导词。 分析句子可知,本句为定语从句。先行词为the speed,at the speed of...意为以...的速度,是固定搭配,所以与the speed搭配必须用介词at。根据先行词the speed,是物,可知应用which引导,故选D。 句意:光速据说是宇宙最快的。
the speed of light也可以解读为“光所拥有的速度”，这就如同the speed of water, the speed of a car一样的结构。此时， the speed of light=light's speed。对“光所拥有的速度”the speed of light, the与speed耦合更紧密一些，而对“神话光速”，speed与light更紧密。将“光所拥有的速度”视为像车速...
What if you traveled faster than the speed of light? What can travel at the speed of light? What is the speed of light per minute? How to calculate the speed of light. What is the speed of light in mph? What is the value for the speed of light?
Nothing! Light is a "universal speed limit" and, according to Einstein's theory of relativity, is the fastest speed in the universe: 300,000 kilometers per second (186,000 miles per second). Is the speed of light constant? The speed of light is a universal constant in a vacuum, like...
What is the speed of light in a vacuum? A. 300,000 kilometers per second. B. 200,000 kilometers per second. C. 100,000 kilometers per second. D. 400,000 kilometers per second. 相关知识点: 试题来源: 解析 A。本题考查科普知识,光在真空中的速度是 30 万千米每秒。其他选项的速度都...
相关知识点: 试题来源: 解析 A。“value”有“数值;价值”的意思,“constant value”表示“恒定值”,在描述光速时常用“constant value”,A 选项符合。“number”侧重于数字;“amount”常指数量;“figure”更多指数字或图形,均不符合描述光速是恒定值的语境。反馈 收藏 ...
10.【翻译】据说光传播的速度是宇宙中最快的。 [考点] 定语从句【精析】 D 考查“介词+ which”引导的定语从句。“以…速度”表为 at the speed of,所以选择介词 at。故选 D。
speed of light- the speed at which light travels in a vacuum; the constancy and universality of the speed of light is recognized by defining it to be exactly 299,792,458 meters per second light speed,c constant- a number representing a quantity assumed to have a fixed value in a specifie...
