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>

Answer:
Moon
Explanation:
although the moon is by far the smallest mass of the listed bodies, it is also by far the closest.
Its acceleration will be 0.825 m/s²
What is Acceleration ?
Acceleration is the rate of change of velocity. It is measured in m/s²
Given that a car is driving 8.5 m/s, and speeds up to 11.8 m/s over a period of 4 seconds.
The parameters to consider are;
- Initial velocity u = 8.5 m/s
- Final velocity v = 11.8 m/s
a = Δv ÷ t
a = (v - u) / t
a = (11.8 - 8.5) / 4
a = 3.3 / 4
a = 0.825 m/s²
Therefore, its acceleration will be 0.825 m/s²
