An electron is accelerated uniformly at a rate of 25,000 km/s from rest in an accelerator, over a distance of 125 km. what is the final velocity of the electron?

2500km/s

Explanation:

use equation wich conects distance and  acceleration:

S=Vst+at²/2

Vs=0km/s(from rest)

S=at²/2

S2=at²

t=√2S/a

t=√2*125km/25000 km/s²

t=0.1s

Vf --final velocity

Vs-- start velocity

a=Vf-Vs/t

at=Vf-Vs

Vs=0Km/s

at=Vf

25000Km/s*0.1s=Vf

Vf=2500Km/s

explanation: in any substance/object, the particles inside it (atoms/molecules) constantly move in random directions and with random speeds (this motion is called brownian motion). as a result, the particles have some kinetic energy (which is proportional to the temperature of the substance).

explanation:

have a great day!
