16.Soundtravels (travel) through air at a speed of about 340metres per second. 相关知识点: 试题来源: 解析 分析 声音在空气中的传播速度是大约每秒340米. 解答 答案:travels.声音在空气中的传播,这是一个自然现象,所以要用一般现在时.根据主语是sound,结合英语提示travel,所以要用travels.故填travels. ...
【解析】答案:travels 核心短语/词汇:sound:声音 travel through air:通过空气传播 at a speed of:以---的速度 per second:每秒 句子译文:声音以大约每秒340米的速度通过空气 传播。 解析:这是一个考查时态的题目,本题叙述的客观 事实,因此用一般现在时,主语sound是第三人称 单数,因此谓语动词也用相应的第三...
The light travels as a wave with a definite speed. This speed varies if the medium of travel changes in its path. The speed of light gets slower if the medium is denser. The fastest speed of light is in the vacuum, c=3×108 m/s ...
Is the speed of light constant? The speed of light is a universal constant in a vacuum, like the vacuum of space. However, light *can* slow down slightly when it passes through an absorbing medium, like water (225,000 kilometers per second = 140,000 miles per second) or glass (200,...
What is the speed of electromagnetic waves in air? What is the speed of light measured in? How fast does light travel? What if you traveled faster than the speed of light? What is the speed of light in feet per second? What if the speed of light was not constant?
humans will continue to find ways to go faster over land and water and through the air.Humans probably will not be satisfied until we are traveling at the speed of light . At that speed , we could circle the globe more than seven times in a single second ...
Switzerland, is the world’s largest particle physics laboratory. Production of top quarks requires very high energies accessible at the Large Hadron Collider (LHC), which enables scientists to send high-energy particles spinning around a 17-mile underground track at ...
Speed of light can be abbreviated as c; for example, 1 speed of light can be written as 1 c. Learn more about the speed of light. What Is the Speed of Sound? The speed of sound is the distance a sound wave travels through an elastic medium. The speed of sound through air at ...
GENEVA (Reuters) - An international team of scientists said on Thursday they had recorded sub-atomic particles traveling faster than light -- a finding that could overturn one of Einstein's long-accepted fundamental laws of the universe.Antonio Ereditato, spokesman for the researchers, told Reuters...
