Nothing unless it was dug out from roots if not they would grom back in a long period of time
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: The 3rd one
Explanation: Electronegativity is a measure of how strongly atoms attract bonding electrons to themselves.
I might be wrong
Answer:
Heyo
Explanation:
Humus is often used by to fertilize the soil. Aside from adding nutrients, it also loosens the texture of the soil. With a freer texture, air and water can more easily penetrate, and oxygen can reach the plant’s root system faster. Some experts also believe it has the ability to prevent plants from getting hit by the disease.
hope this helps!
