What is the relationship between pressure and gravity in a nebula
Levart [38]
<span> la gravedad en la tierra no es constante ni mucho menos porque depende de la distancia al centro de la tierra... y la tierra no es perfectamente esferica </span>

<span>respecto a la pregunta, la presion atmosferica viene siendo proporcional al peso que el aire ejerce sobre nosotros. Mientras mas gravedad hay en un planeta, mayor es la presion atmosferica a cierta altura. </span>

<span>Ahora, en un mismo planeta, la aceleracion de gravedad disminuye con la altura (porque se esta mas lejos del centro) y la presion tambien disminuye con la altura, porque hay menos aire sobre nuestras cabezas. </span>

<span>espero q te sirva.</span>

When a soda can is dropped, it should not be immediately opened. Why?
umka2103 [35]
When soda companies add carbon dioxide gas to a soda mixture, the water is very cold so it can hold a lot of gas. They also use pressure to put more gas in the water than it could normally hold at that temperature. But when a soda can warms up a bit or when the can is shaken, that extra gas is really ready to come out. So when you open up the can and release the pressure, splooosh!

If the partial pressure of oxygen outside of a cell is 100 mmHg and the partial pressure of oxygen inside of a cell is 25 mmHg,
mrs_skeptik [129]

" There will be a net movement of oxygen from outside the cell to inside the cell " Statement is True.

Explanation:

The partial pressure for oxygen in alveoli is greater under normal circumstances, and oxygen moves neatly into the blood. In addition, the partial carbon dioxide pressure throughout the blood usually is higher, such that carbon dioxide migrate clearly into the alveoli.

The few common molecules which can traverse the cell membrane by absorption (or diffusion of a sort recognized as osmosis) are water, carbon dioxide and oxygen. Metabolism is typically oxygen-needed, which is lowest in the cell within the animal and plant, so that net oxygen flows to the cell.
