24: For vector A and vector B, the following is given: A - +5 unit, Ay - - 3 unit, B. - - 2 unit and B, - +1 unit. (a) Find the magnitude and direction of vector C where C - A+B. (b) Find the magnitude and
direction of the vector D where D=A-B. [3.6 unit, -33.7° (4h quad): 8.06 unit, -29.7º (4h quad ]

answer: decibel

explanation:

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.
