Part E Now, show both horizontal momentum, px, and vertical momentum, py, in the Table. Also change the graphs to display px and py against time. Based on the table values and the graphs, what can you say about your prediction regarding momentum?

temp rises, and expansion

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.

find the sum of the two horizontal vectors and the sum of the two vertical vectors
