Answer: 9.0 atm
Explanation:
To calculate the new pressure, we use the equation given by Boyle's law. This law states that pressure is directly proportional to the volume of the gas at constant temperature.
The equation given by this law is:

where,
are initial pressure and volume.
are final pressure and volume.
We are given:

Putting values in above equation, we get:

Thus new pressure of 150 ml of a gas that is compressed to 50 ml is 9.0 atm
Answer:
No
Explanation:
Your answer will be no because Mars has less gravity then Earth does but you would still have the same amount of mass therefor If someone goes to Mars and goes back to Earth they would not weigh the same as they did on earth.Hope it helps you!
I'm sorry I am not surely understanding what you a re trying to ask here
Answer:
Distance travelled is 7 meters and the displacement is 3 meters
First we'll calculate the energy it posesses
G.P.E = mgh = 0.2 * 10 * 100 = 200 J
Now we'll calculate the temperature rise
Q = m * c * (t2 - t1)
Q/(m * c) = t2-t1
t2 = Q/(m * c) + t1 = 200/(0.2 * 400) + 0 = <span>2.5 C</span>
