De ani desciende. Realiza un dibujo donde tengas la siguiente situación: una bala de cañón
arrojada de manera vertical, con una velocidad inicial de -50 m/s. ¿Cómo
debes dibujar el vector aceleración de la gravedad? ¿Qué pasa en la altura
máxima con la velocidad? Dibuja claramente el sistema de referencia.

good looking response

a longitudinal wave moves energy that is to the direction of the wave’s movement. - true

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.

i need with 1.3.2 investigate cycling o2 and co2 apex

we need to see it
