I would say "B" because for it to change into a liquid energy must be applied to it and thus it is going through a chemical change.
Answer:
<em>A not reasonable explanation for an aerospace engineer designs a rocket to have three stages is</em>:
- <u><em>A. To simplify the design of the rocket</em></u>
Explanation:
A <em>three stages rocket</em> permits to separate the fuel compartments. The rocket must be launched with a huge amount of fuel to last the entire travel. Then the initial mass of the rocket and the fuel is considerably large.
As the rocket flies, part of the fuel is consumed and so some compartements may be separated and removed decreasing the mass of the rocket as it flies (<em>option D. </em>is a reasonable explanation), so the rocket only carries the necessary mass (<em>statement B</em>. is a reasonable explanation).
As the rocket moves away from Earth, the gravitational force decreases and, in the space, the amount of thrust needed is lesser, which the aerospace engineers take into account for the design (choice C. is a reasonable explanation).
The only <em>not reasonable explanation to design a three stage rocket</em> is to <em>simplify the design of the rocket</em>: designing a rocket with three modules each with different features, functions, and the detachment mechanisms brings lot of complex problems to solve. So, o<em>ption A. </em>is the correct answer.
Answer:
Place the experiments on a scale
Explanation:
If you place two of the same experiments on a scale, and cover one with a cup, the one with the cup will "lose" mass, while the other won't, due to the cup being a "containment field" I guess you could call it.
