1. Una carga de 12 uc se encuentra en el centro de una esfera metálica electrizada. El radio de la esfera es de 30 cm, calcula:
a) La intensidad del campo eléctrico en la superficie de la esfera.
b) La intensidad del campo eléctrico a 15 cm de la superficie de la esfera.
c) La intensidad del campo eléctrico a un metro de la superficie de la esfera.​

thermal energy is the answer

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.
