It was the same sound as when someone strikes a bell of this kind, which is completely encompassed in his hand, with a hammer. The bell, then, produces a rather dull sound or noise but no real ringing tone. On the other hand, the receiver was no sooner opened for the air to return...

In the living room, you hear the sound of a vacuum cleaner. What are people doing? A. Decorating the room B. Cleaning the room C. Moving furniture 相关知识点: 试题来源: 解析 B。解析:听到吸尘器的声音,这是在打扫房间,而不是装饰房间或者移动家具,所以排除A和C。
The speed of sound in air is definite. But the speed of light in a vacuum is much ___. A. definite B. indefinite C. fast D. slow 相关知识点: 试题来源: 解析 C。“definite”在这里不是反义词的考查点。声音在空气中的速度是确定的,而光在真空中的速度比声音快很多。考查了对不同物理现象...
Why cannot sound travel through a vacuum?Sound WaveSound waves are produced by the vibration of the object and rely on the transmission of this vibration trough interaction of atoms in its medium. Sound wave speed of propagation varies from medium to medium compact medium propagates sound wave ...
HoRNet Valvola(the Italian word for vacuum tube) is an emulation of the electric behavior of a vacuum tube and its surrounding circuit. Vacuum tube emulation in all its nuances The plugin’s sound is as close as possible to real tube behavior. This is because the code directly models the ...
What Happens When a Sound is Made in a Vacuum? Sound is a pressure wave traveling through a medium. If you place a ringing bell inside a vacuum, the bell can still ring and you could see it ringing, but you will not be able to hear it since their is no air around the bell to ...
A. water B. vacuum C. wood D. glass 相关知识点: 试题来源: 解析 A。此题涉及声音传播的知识。声音在水中传播比在空气中快。B 选项“vacuum”表示“真空”,声音在真空中不能传播;C 选项“wood”和 D 选项“glass”虽然能传播声音,但速度不如在水中快。反馈...
In general, any non-canonical k-essence model has an evolving speed of sound. One has to choose a model in such a way that the sound speed is always subluminal because we do not expect any information to propagate faster than the speed of light in a vacuum. Also, the sound speed has...
Requires a medium to travel, cannot propagate in a vacuum. Sound travels faster in water than in air due to the medium's density. 8 Sonic The term "sonic" is often associated with speeds at or exceeding the speed of sound. Sonic aircraft are designed to fly at speeds faster than sound...
