Hello,
The answer is "universe, Milky Way, clusters, stars, planets".
Reason:
The universe would be the biggest because it has all the galaxy's, starts, clusters, and planets into one. Then it would be Milky Way because this is a galaxy that contains: stars, planets, and clusters. Then it would be clusters because that contains stars, or planets in one group. Then be stars because stars are bigger than planets. Then it would be planets. Therefore the order should go like this: <span>Milky Way, universe, planets, clusters, and stars.
If you need anymore help feel free to ask me!
Hope this helps!

Answer:
If efficiency is .22 then  W = .22 * Q   where Q is the heat input
Heat Input    Q = 2510 / .22 = 11,400 J 
Heat rejected = 11.400 - 2510 = 8900  J of heat wasted
Also, 8900 J / (4.19 J / cal) = 2120 cal

Answer:
 For every action, there is an equal and opposite reaction. The statement means that in every interaction, there is a pair of forces acting on the two interacting objects.
Explanation:
Every force sent into an object will sent a force in return.
