¿Cuánto se demora el sonido en recorrer 3 metros de un cable de cobre, si su rapidez en él es de 3810 m/s

1270 segundos

Explanation:

Dada,

Velocidad ( v ) = 3810 m/s

Distancia ( s ) = 3 m

Encontrar : -

Tiempo que tarda el sonido en viajar ( t ) = ?

Fórmula : -

s = d / t

t = d / s

= 3810 / 3

t = 1270 segundos

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
