A una tobera adiabática entra dióxido de carbono de una manera estacionaria a 1 Mpa y 500 0C, a una tasa de flujo  másico de 6000 kg/h y sale a 100 kPa  y 450 m/s . El área de entrada a la tobera es de 40 cm2
Determine
1.-  La velocidad de
entrada   
2.-  la temperatura de salida.

in simple terms, the principle states that the buoyancy force on an object is equal to the weight of the fluid displaced by the object, or the density of the fluid multiplied by the submerged volume times the gravitational acceleration, g. this is also known as upthrust.

the answer is a 3.8cm

explanation:

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.
