the denser the medium the faster the sound of speed.
it is experimentally proved. for example if a train is appraching and you cant hear the sound you can hear it if you put your head (ear) on the railtrack.
but do move quickly if you see the train approaching.....
C. iron, because it is the most dense of the listed materials
it travels through rock quickest even if they are both solids eking
Air travel is usually the quickest.
Since sound is a mechanical wave (it needs a substance to travel through) it cannot travel through a vacuum.
Yes
throw vacume
No, sound requires a medium to travel.No it must travel through matter
plane...
To fly, I believe.
Different sounds are made because they make different sounds waves. Sounds are made from vibrations abd also they travel through air particles...
tiny viberations are carried through the air and into your ear and they travel at 800ft per second
Sound is a vibration when something makes a noise every thing around vibrates in order to make the sound for it to travel it needs particles to vibrate there is almost no matter in outer space hence no particles
