Mechanical advantage is the answer.
Option B.
<h3><u>Explanation:</u></h3>
A machine is defined as the instrument which is used to perform some task easily, and with ease. A machine has the capability to give an output force in exchange of an input force. Now the ratio of the output force to input force is called as the mechanical advantage.
Mechanical advantage = Output force / input force.
For example, in case of a lever, there are three types - first class lever, second class lever, and third class lever. Mechanical advantage for a second class lever is always more than one, as we get more output force than input force. Similarly, the mechanical advantage for a third class lever is always less than 1, and mechanical advantage of first class lever can be both more or less or equal to one.
The statement that best describes the dust gas and celestial bodies of the Milky Way galaxy is that -<u>They orbit around the center of the galaxy because of gravity.</u>
<u />
Explanation:
- <u>The Milky way is referred to as a spiral galaxy ,our sun,and all the planets are a part of this galaxy.</u>
- <u />
- <u>A galaxy is often said to be a large group of dust gas and celestial body (i.e nebula, stars, comets, meteors, asteroids, and planets.) bounded together with gravity.</u>
.
So we can say that the statement that best describes the dust gas and celestial bodies of the Milky Way galaxy is that -<u>They orbit around the center of the galaxy because of gravity.</u>
