B. The Sun is only one of billions of stars in the galaxy, many of which are very similar to the Sun.

Explanation:

The sun is only one of the billions of stars in the galaxy, many of which are very similar to the sun.

The sun is the only star in the solar system which is made up the planets, their satellites and other planetary bodies.

There are several systems of stars in the universe.
A cluster of stars is known as the Galaxy.
The name of our Galaxy is called the Milky Way.
A several groups of Galaxies makes up the universe.
The sun is a star power by nuclear fusion of light atoms in its core.

12.36Un balón lleno contiene 12 kg de oxígeno, O2, bajo una presión ma-nométrica de 40 atm. Determine la masa de oxígeno que se

const2013 [10]

Answer:

Quedan 7.317 kilogramos de oxígeno en el balón y se extraen 4.683 kilogramos de oxígeno en el proceso.

Explanation:

Asúmase que el balón es rígido. Supongamos que el oxígeno se comporta como un gas ideal, entonces la ecuación de estado es la siguiente:

$P\cdot V = \frac{m\cdot R_{u}\cdot T}{M}$ (1)

Donde:

$P$ - Presión, medida en atmósferas.

$V$ - Volumen, medido en litros.

$m$ - Masa, medida en kilogramos.

$M$ - Masa molar, medida en kilogramos por kilomol.

$T$ - Temperatura, medida en Kelvin.

$R_{u}$ - Constante de los gases ideales, medida en atmósfera-litros por kilomol-Kelvin.

El aire experimenta un proceso isocórico e isotérmico, entonces obtenemos la siguiente relación:

$\frac{P_{1}}{m_{1}} = \frac{P_{2}}{m_{2}}$ (2)

Nótese que los subíndices 1 y 2 representan los estados inicial y final de proceso.

Si sabemos que $P_{1} = 41\,atm$ , $m_{1} = 12\,kg$ y $P_{2} = 25\,atm$ , entonces la masa final del aire es:

$m_{2} = \frac{P_{2}}{P_{1}} \cdot m_{1}$

$m_{2} = \left(\frac{25\,atm}{41\,atm}\right)\cdot (12\,kg)$

$m_{2} = 7.317\,kg$

La masa que se ha extraído del balón es:

$\Delta m = m_{1}-m_{2}$

$\Delta m = 12\,kg-7.317\,kg$

$\Delta m = 4.683\,kg$

Quedan 7.317 kilogramos de oxígeno en el balón y se extraen 4.683 kilogramos de oxígeno en el proceso.

Answer:

Explanation:

It isn't any of the others and the competitive exclusion principle talks about how two similar species cannot coexist under the same resources for long. I suppose you could conclude they were trying to fullfill the same niche, but only under the assumption of comp. exclusion. So just B.
