Brainliest will be given if correct! i can check too..

the planets hox and blox are near each other in the dorgon system. the dorgons have very advanced technology, and a dorgon scientist wants to increase the pull of gravity between the two planets.

which proposals would the scientist make to accomplish this goal? check all that apply.

decreasing the distance between hox and blox
increasing the mass of hox
increasing the distance between hox and blox
decreasing the mass of blox
increasing the mass of hox and blox
decreasing the mass of hox and blox

Decreasing the distance between Hox and Blox

Increasing the mass of Hox

Increasing the mass of Hox and Blox.

Explanation:

According to the law of universal gravitation:

Where:  

is the module of the attraction force exerted between both bodies  

is the universal gravitation constant.  

and are the masses of both planets.  

is the distance between both planets.

As we can see, the gravity force is directly proportional to the mass of the bodies and inversely proportional to the square of the distance that separates them.

In other words:

If we decrease the distance between both planets (Hox and Blox), the gravitational pull between them will increase.  

On the other hand, if we keep the distance between Hox and Blox, but we increase the mass of one of them, or increase the mass of both, the gravitational pull between them will also increase.
