How much energy is needed to move 15x10^20 electrons through a potential energy of 10 volts

answer; (d) spontaneous processes are characterized by the overall conversion of order to disorder;

no simpler subs form complex ones. synthesise = make

does anyone know or what?

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.
