En un depósito de gran capacidad, lleno de
agua, se tiene un orificio situado a 8 m por
debajo de la superficie libre del líquido.
Sabiendo que en dicha superficie se ejerce
una presión de 208 kPa, determinar la
velocidad, en m/s, del chorro de agua que
sale por el orificio. (2g m s = 10 /).
a) 8
b) 12
c) 16
d) 24
e) 20

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.
