You pull a sled full of firewood that combines for a mass of 50kg at 32° from the horizon along a flat surface using a force of 82.13N. The sled is accelerating at 0.5m/s2, and the coefficient of friction between the sled and the snow is uk = 0.1. What is the Normal Force on the sled?

explanation:

explanation:

newton's third law, for every action there is an equal and opposite reaction.

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.

so easy. just google the electromagnetic waves and it’ll pop up.
