Answer:
<h2><u>✍</u><u> </u><u>What is quantum physics?</u></h2>
- ➳ It's the physics that explains how everything works; the best description we have of the nature of the particles that make up matter and the forces with which they interact.
- Quantum physics underlies how atoms work, and so why chemistry and biology work as they do.
Explanation:
Let
= distance traveled while accelerating
= distance traveled while decelerating
The distance traveled while accelerating is given by
We need the velocity of the rocket after 30 seconds and we can calculate it as follows:
This will be the initial velocity when start calculating for the distance it traveled while decelerating.
Solving for we get
Therefore, the total distance x is
The effiency of a machine is
(output work or energy) / (input work or energy) .
For the system described in the question, that's
(123 J) / (150 J) = 0.82 = 82% .
They are related because they are all important elements in physical science. They all deal with motion and the movement of molecules ( also volume).

True. The amount of water on Earth is consistent even if it is displayed in different forms.
