In a parking garage, both cars were parked in their own respective spaces, one behind the other. The blue car's driver accidently pressed the accelerator pad instead of the brake pad, thus backing into the green car. The force applied by the blue car was 15N and the mass of the blue car is 1500kg. What was the rate of acceleration of the blue car backing into the green car?

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.

im srry but ur wrong the answer is d a smooth rock, some red dirt, and an empty bird's nest.

magnets not strong enough
