Responder:
18.75 atmósferas
Explicación:
Paso uno:
datos dados
volumen inicial V1 = 25L
Presión inicial P1 = 7.5 atm
volumen final V2 = 10L
presión final P2 = ??
Segundo paso:
Aplicando la expresión de gas que relaciona el volumen y la presión, es decir
P1V1 = P2V2
sustituyendo nuestros datos tenemos
7.5 * 25 = P2 * 10
187.5 = P2 * 10
divide ambos lados por 10
P2 = 187.5 / 10
P2 = 18.75 atmósferas
<em><u>La presión final es de 18.75 atm.</u></em>
The masses of two bodies their distance apart and the gravitational contents G is in every day case i.e. close to the earth surface the gravitational field is considered to be constant.
I believe it's the law of Inertia, I learned this in 8th grade, but that was a while ago. I do believe it's the law of Inertia though.
Answer:
m = 5.27e18 kg
Explanation:
The pressure of a fluid is the weigth of a column of that fluid over base of that column.
The weight of the column is its mass multiplied by the acceleration of gravity. The acceleration of gravity varies with height, however the variation is small and can be ignored, consifering the acceleration of gravity constant.
So:
If we consider the entirety of the atmosphere as a single column the base would be the surface of Earth. Approximating Earth as a sphere:
Now, we can obtain the mass of the atmosphere:
