The final volume of the gas is 144.25 L
Explanation:
For an ideal gas kept at constant pressure, the work done by the gas on the surroundings is given by
where
p is the pressure of the gas
is the initial volume
is the final volume
For the gas in the cylinder in this problem,
p = 2.00 atm
And we also know the work done,
W = 288 J
So we can solve the equation for , the final volume:

Answer:
The angular momentum of a cylinder, when it is rotating with constant angular velocity is Lini =Iωi
. When two cylinders are added to the rotating cylinder, which are identical in their dimensions, the moment of inertia of the entire system increases (since mass increases). The final moment of inertia will be 3I
Since friction exist, all the cylinders start rotating with same angular velocity, the new angular velocity can be calculated using conservation of angular momentum
Thus, Iωi =3Iωf ⟹ωf =ωi/3 = 0.33ωi
Answer:
B. Northern Canada
Explanation:
A continental polar air mass can form over the land during the winter months. In the Northern Hemisphere, it originates in northern Canada or Alaska. As it moves southward, it brings dry weather conditions to the United States. Temperature and humidity levels are both low. Hope this helps :)
<span>Near the equator, the patterns of convection currents are called
Hadley Cells.</span>
Hadley Cells refers to the low-latitude overturning movements that
have air increasing at the equator and air dropping at roughly latitude of 30
degree and these cells are also responsible for the trade winds in the Tropics
and control low-latitude patterns of weather.
Answer:
magnitude:
formula: v=√(x)^2 + (y)^2 + (z)^2
√(2.5)^2 +(3)^2 + (7.8)^2
√76.09
=8.7
I hope this helped :)
