Ariana is accelerating her car at 4.6 m/s2. it took her 10 seconds to reach this acceleration. her starting velocity was 0 m/s.

what was her final velocity?

a. 0 m/s

b. 2.3 m/s

c. 4.6 m/s

d. 46 m/s

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.
