Add a third force that results in a net force of zero. draw the vector starting at the black dot. the location, orientation, and length of the vector will be graded. you can move the vectors f⃗ 1 and f⃗ 2 to construct the required vector, but be sure to return them into their initial positions before submitting the answer.

lol

explanation:

answer;

d. are made mostly of liquid

explanation;

-the general   composition and structure planets includes; they have a thick gas and liquid layer covering a small,solid core. mostly the gases are hydrogen and helium atmosphere and layers of liquid hydrogen. for instance neptune and uranus are examples of the outer planets, they have a core covered by ice and ammonia.

-neptune's atmosphere is hydrogen and helium with a bit of methane so there is no oxygen to breath and the interior is made up of frozen water and ammonia with a rock and iron core. thus, there is no liquid water or solid surface to survive.
