A quick thinking 50 kg physics student uses a bedsheet as a makeshift parachute to escape a burning dormitory. The bedsheet provides 400 newtons of air resistance. At what rate does the student accelerate downward? How fast will she be falling when she hits the ground if she jumps from a height of 16 m?

beta is electron from nucleus

something from nucleus has changed, but charge must be same for cons of charge

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.
