The speed of light is a fundamental constant in physics. The word “constant” means ___. A. 变量 B. 常数 C. 速度 D. 时间 相关知识点: 试题来源: 解析 B。“constant”的中文意思是“常数”。“变量”是“variable”;“速度”是“speed”;“时间”是“time”。
结果1 题目The speed of light and the laws of physics ( ) constant. A. is B. are C. was D. were 相关知识点: 试题来源: 解析 B。本题考查主谓一致。“The speed of light and the laws of physics”是复数概念,所以谓语动词用 are。

The speed of light is considered a fundamental constant of nature. Its significance is far broader than its role in describing a property of electromagnetic waves. It serves as the single limiting velocity in the universe, being an upper bound to the propagation speed of signals and to the sp...
Speed of light Speed Speleology The speed of light in vacuum, commonly denoted c, is a universal physical constant important in many areas of physics. Its value is exactly 299,792,458 metres per second, a figure that is exact because the length of the metre is defined from this constant ...
as a universal constant, scientists and science fiction writers alike spend time contemplating faster-than-light travel. So far no one's been able to demonstrate a real warp drive, but that hasn't slowed our collective hurtle toward new stories, new inventions and new realms of physics. ...
Speed of LightMass DistributionEnergy of PhotonFundamental Laws of PhysicsThe speed of light is normally assumed to be a fundamental constant of nature. In this essay, I propose that the speed of light is not a fundamental constant, but, rather, it is a consequence of the execution of ...
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 sp...
Although the speed of light remains a constant right now, we have to be prepared for the possibility that there might be some changes. That Einstein’s theory of relativity may be wrong. And all the other laws of physics that we know might become open to contention as well. ...
In the physics experiment, the data ___ that the speed of light is constant. A. shows B. show C. showed D. showing 相关知识点: 试题来源: 解析 A。解析:data是不可数名词,虽然形式上看起来像复数,但在英语中当作单数看待,所以谓语动词用第三人称单数形式shows。
