Ineed a answer quick which of the following are correct statements about electrons a. the valence shell is the furthest shell from the nucleus b. there are four electrons in every electron shell c. electrons are in the nucleus of an atom d. electrons are located in layers around the nucleus

An electron moves with a constant horizontal velocity of 3.0 × 106 m/s and no initial vertical velocity as it enters a deflector inside a tv tube. the electron strikes the screen after traveling 26 cm horizontally and 19 cm vertically upward with no horizontal acceleration. what is the constant vertical acceleration provided by the deflector? (the effects of gravity can be ignored.)
