A 40 cm-long thin wire has a linear charge density of 10 C/cm, and a small particle (positioned 10 cm away from the center of the wire) is uniformly charged to 10 C. What is the electric field strength E (magnitude and direction) exactly midway between the particle and the wire

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.
