Uma partícula de carga q = 5,0 μC e massa m = 0,0004 kg, colocada num ponto P do espaço adquire aceleração de 2000 metro por segundo quadrado. Qual é o módulo do vetor campo elétrico E nesse ponto? ​

where are the vectors ?

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.
