PLEASE HELP Proton in an electric field

A proton of mass 1.67 x 10-27 kg enters the region between two parallel plates a distance 38.0 cm apart. There is a
uniform electric field of 3.00 x 104 V/m between the plates. If the initial speed of the proton is 2.00 x 106m/s what is it's
final speed?

electric

explanation:

answer: i don't know the answer good luck

explanation:

the temperature in kelvin of 2.0 dm3 of an ideal gas is doubled and its pressure is increased by a factor of four. what is the final volume of the gas

when jerome paddle in flowing river towards east the net speed of jerome will increase

so the net speed of jerome will be given as

now the speed of paul will be same as it is given as he is running on the ground

so

so here we can say since the speed of jerome is more so he will win the race

now as we know the distance so the time difference is given as

so jerome will reach first and the time difference will be 203.55 s or 3.4 min
