Avan de graaff generator is one of the original particle accelerators and can be used to accelerate charged particles like protons or electrons. you may have seen it used to make human hair stand on end or produce large sparks. one application of the van de graaff generator is to create x-rays by bombarding a hard metal target with the beam. consider a beam of protons at 1.90 kev and a current of 4.95 ma produced by the generator. (a) what is the speed of the protons (in m/s)?

603383.67253 m/s

Explanation:

m = Mass of proton =

K = Kinetic energy = 1.9 keV

Velocity of proton is given by

The speed of the protons is 603383.67253 m/s

it would be c. predictability

russian is not my first language, so i'm afraid i can't write out an answer in russian, but hopefully you can find a way to do so. here's my best translation of the problem: you're given a plot of a particle's position in one-dimensional space over time, and you're asked to find either the total distance traveled by the particle after 6 seconds had elapsed, or the total displacement of the particle after 6 seconds.

if you want the total distance traveled, you would first need to determine the particle's velocity as a function of time, then integrate that over the 6-second interval. we know the position function is quadratic with roots at 0 and 6, so we have

where is unknown. because the position is parabolic, there is symmetry about the midpoint at , and we know that

so that the position function is

which means the velocity is

then the total distance traveled is

so the total distance traveled is 20 m.

on the other hand, if you want to find displacement: the particle starts at and ends at , so its displacement is 0.
