As more resistors are added in series to a constant voltage source, the power supplied by the source Group of answer choices increases. decreases. does not change. increases for a time and then starts to decrease.

P = I V       power produced by source at voltage V thru resistance R

I = V / R      current thru resistance R

P = V^2 / R

Power produced will decrease as the output resistance R increases

Check: if R increases to ∞ the power produced will go to zero

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.
