In a television picture tube, electrons strike the screen after being accelerated from rest through a potential difference of 27,800 v. the speeds of the electrons are quite large, and for accurate calculations of the speeds, the effects of special relativity must be taken into account. ignoring such effects, find the electron speed just before the electron strikes the screen.

Explanation:

As we know that electrostatic potential energy of the electron is converting here into kinetic energy

so we will have

so here we know that

so from above equation we have

32: from largest to smallest, this hierarchy includes eons, eras, periods, epochs, and ages.

33: answer is c
