Physics
An electron is projected with an initial speed vi = 3.35 × 10^5 m/s directly toward a very distant proton that is at rest. because the proton mass is large relative to the electron mass, assume that the proton remains at rest. by calculating the work done on the electron by the electrostatic force, determine the distance between the two particles when the electron instantaneously has speed 2vi.

Ответ:
Responder: 480 vatios
Explicación:
La potencia en un circuito eléctrico am puede expresarse como el producto si la corriente y el voltaje en el circuito.
Potencia = corriente × voltaje
Corriente dada = 4 amperios
Voltaje = 120 voltios
Potencia gastada en el circuito = 4 × 120
Potencia gastada en el circuito =
480 vatios
