It is important to keep terms electrical potential and electrical potential energy straight. Let's say a charge q is placed at a point where the electrical potential is V. If I double the charge to 2q, the electrical potential of the point will and the electrical potential energy of the charge will 1. stay the same; double 2. double; stay the same 3. stay the same; stay the same 4. double; double

no idea for this because

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.
