Currently there are no regular vehicles that are faster than the speed of sound, although both the Concorde, and its Russian copy were faster than the speed of sound. There are plenty of military aircraft that are faster than the speed of sound. All spacecraft capable of reaching orbit are faster than the speed of sound. There have been two or three experimental vehicles, "cars", that have gone faster than the speed of sound as well.
No, the speed of sound is faster in solids.
The speed of light is much greater than the speed of sound.
The loudness of the sound has no effect on its speed.
The Sound of Speed was created in 1988.
As a rule the speed of sound increases with increasing density of the medium.
The speed of light is about 900,000 times as fast as the speed of sound in air.
No, not quite. The sound travels at the speed of sound to your ear.
the sound travels at the speed of sound, but the gasses dont
No. "Speed" and "theme" have the same sound (long E or EE). The words "sped" and "them" have the same sound (short E).
The speed of sound depends on the air factors around it
