An object is given an initial velocity. what will happen to the object if no other forces act on it?

Explanation:

That means no Gravitational Force (g) acting on the object.

If we look the Newton's 2nd Law , we will see that the force (F) and gravitational force (g) is dependent each other , and the mass (m) is a coefficient between them.

fgravity=10x10=100n case 1

fgravity=30x20=600n case 2

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.
