Which material has magnetic domains and can be made into a magnet a) a glass bottle b) an aluminum can c) a plastic fork d)an iron nail

Iron nail

Explanation:

A glass bottle does not contain magnetic material and can't align towards magnetic pole likewise a plastic fork because they are materials that do not have magnetic properties. An aluminium can is made from aluminium which is a weak magnet and can't be made into a magnet. An iron nail is made up of iron which is a strong magnetic material because of the presence of dipole moments and the alignment of its electrons makes its ferro-magnetic and good material for magnetic substance.

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.
