<u>The following proposals would make the scientist to accomplish this goal:</u>
- decreasing the distance between Hox and Blox
- increasing the mass of Hox
- increasing the mass of Hox and Blox
Answer: Options A, B, and E
<u>Explanation:</u>
The gravitational pull on an object by another, is nothing but the force that it exerts due to its gravity. Earth has gravity, so it pulls down everything that tends to move up. Similarly, Hox and Blox have gravitational pulls on each other, due to their gravitational forces.
Where,
F = force exerted on object
G – Gravitational constant
– Mass of two objects
r – Distance between two objects
This gravitational pull varies in phase with the mass of two bodies in relation, and inversely proportionate to the distance square. Hence, the scientist could do less the distance between the bodies, or else, spend to increase the size of one of them or both the bodies.

Answer:
She will use one 2 as a subscript.
Explanation:
Nitrogen is a chemical element with the symbol "N" and has an atomic number of 7. Thus, it is found in group (5) of the periodic table and as such it has 5 electrons in its outermost shell. Therefore, nitrogen has two (5) valence electrons.
On the other hand, oxygen has an atomic number of 8 and with the symbol "O."
When nitrogen and oxygen react chemically, they produce a compound known as nitrogen dioxide
In this scenario, Jenny is studying a compound that has two oxygen atoms and one nitrogen atom. Therefore, the statement which describes the subscripts she will use to write the chemical formula is, she will use one 2 as a subscript.
Where: 2 represents the subscript of oxygen.
