1. Two forces act on a box as follows: F= 100 N at 02 = 170. and F2= 75 N at O2 = 30. Find their resultant force on the box.

(b) the direction of of the vector sum F1+F2​

Explanation:

i would think it's food chain

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.
