Justin Verlander throws a pitch from the mound 30 m away from home plate at 255 m/s. How fast does Chris Sale need to throw a pitch from second base, 45 m away, to have his pitch arrive at the same time?

electromagnetic waves travel through space with vacuums. give me brainliest if right.

it doesn't. it was imagined up in the middle ages.

it's when something is going so fast it makes a loud noise, breaking the sound barrier, for example: a jet makes a loud noise, not only cause of the jet but because they reached a point where they went so fast that you can year the noise from various parts, kinda like a police car, lets say the car was going   so fast that you hear the siren of the cop car right next to you, but the car is probably a mile a way, it's cos the siren was next to you a few seconds if you understand me
