Aproton has been accelerated from rest through a potential difference of -1000 v . part a what is the proton's kinetic energy, in electron volts?

kinetic energy of the proton will be 1000eV

Explanation:

As we know that change in potential energy of a point charge when it is passed through a given potential difference is given by the formula

here we know that

charge is due to a proton

potential difference is given by

so here we will have

now by mechanical energy conservation law we know that

so here we have

b) returns freshwater to the earth.

c) returns freshwater to the earth.c) occurs after condensation.

d) returns freshwater to the earth.c) occurs after condensation.d) roughly equal to the amount of evaporation.

pls mark as brainliest.

waves moving from a fast medium to a slow medium will experience a reflection as light travels more slowly than red light. total internal reflection occurs when the critical angle is.
