There are four basic forces in nature: gravity, the electromagnetic force, the strong nuclear force, and the weak nuclear force. of the four basic forces which acts over the shortest distance? a gravity b electromagnet force c strong nuclear force d weak nuclear force

D. Weak Nuclear Force.

Weak Force is named thus because it is weak compared to the Strong Force. However, it is responsible for holding particles that are smaller than a Proton. Hence, this is the force that acts over the shortest distance, typically of the order of , which is much less than the diameter of a proton.

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.
