The main purpose in the green mile is to enlighten the readers outrage at the inhumanity and capriciousness of the death penalty.
The best way is: B. flat, so that the north pole of the magnets on the train point up and the north poles of the magnets on the track point down.
<h3>What is the law of magnetism?</h3>
The law of magnetism states that the like poles of a magnet repel one another while unlike (different) poles attract each other. Thus, two north (N) poles of a magnet would repel one another while a north (N) and south (S) would attract each other.
Based on the law of magnetism, the best way to arrange the magnets on the train and on the track, so as to allow the model train levitate is flat, as this would make the north (N) pole of the magnets on the train point up and the north (N) poles of the magnets on the track point down.

<u>Complete Question:</u>
Jolie builds a model of a maglev train. She uses disc magnets to levitate the train. A disc magnet has its north and south poles on its faces, as shown.
What is the best way to arrange the magnets on the train and on the track so that the model train levitates?
Krypton (Kr) and bromine (Br) are Period 4 elements that are also called p-block elements. Krypton is a noble gas while bromine is a halogen.
While comparing the stability of the two elements, Krypton is more stable than bromine. This is because being a noble gas, Krypton follows the octet rule and maintains its stability. Bromine has 35 electrons and the outer most valence shell has 7 electrons so its unstable. Krypton has 36 electrons and 8 electrons in the valence shell so its stable.
