Planets as there is no sound in outer space.
the answer is something that is making aloud sound
Sound has no mass. Without matter, there can be no sound. Sound is information which is carried on a wave that moves through matter.
Sound is produced when an object moves or vibrates. Without movement there could be no sound. When an object moves or vibrates, the air molecules around the object also vibrate. Vibrating objects (as long as they are not in a vacuum) produce sound.
It means without making a sound.
You hear a sonic boom
yes sound does moves the sound moves in waves
yes sound does moves the sound moves in waves
Someone making something sound more prominent than usual is called an "Exaggerating" person.
Marriage, virginity, promise...
sound has properties of loudness and pitch. The loudness of a sound depends on the amplitude of vibration. A speaker making a loud sound moves back and forth more than a speaker making a soft sound. The pitch of a sound depends on the frequency of vibration. A speaker making a high pitched sound like a siren vibrates with a higher frequency than the same speaker making a low pitched sound like thunder
suggest it as a group date but then when you're there snag some personal time with your crush :)
Cause a vibration in something. Clap your hands. Hit something.
