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>
he makes 1 m im 300 seconds btw that snails slow lol
The correct answer is
<span>C) Amount of heat absorbed or released is doubled if quantity is doubled. If a different substance with half the specific heat capacity is used, the amount of heat absorbed or released is cut in half.
In fact, the amount of heat released or absorbed is given by:
</span>

<span>where
m is the mass of the substance
Cs is the specific heat capacity of the material
</span>

is the change in temperature
<span>
We can see that Q is directly proportional to both m (mass, or quantity of the substance) and Cs (specific heat capacity). So if the quantity (m) is doubled, the amount of heat (Q) is doubled as well. Similarly, if the specific heat capacity (Cs) is cut in half, the amount of heat (Q) is cut in half as well.</span>
No, it will not fall. The pencil will remain at zero speed relative to the spacecraft and will orbit the earth with the spacecraft.
As the distance from the Sun increases the time to orbit the Sun increases. <em>(a)</em>
Examples:
-- Nearest planet to the sun: Mercury. Time to orbit the sun: 88 days
-- 3rd planet from the sun: Earth. Time to orbit the sun: 1 year
-- 5th planet from the sun: Jupiter. Time to orbit the sun: 12 years
-- 9th closest object to the sun: Pluto. Time to orbit the sun: 248 years
Another pair of examples:
-- Object in a near Earth orbit: International Space Station
Time to orbit the Earth: 90 minutes
-- Object in a far Earth orbit: the Moon
Time to orbit the Earth: 27.3 days
The reason for all of this is: Two things about orbits.
1). The larger the orbit is, the farther the object has to travel around it.
2). The farther out the object is, the slower it travels in its orbit.
This is simply the way gravity works.
