Answer:
The work done is and it is negative because the exterior is doing work on the gas.
The value of the heat flow is and is directed out of the gas, as this is being cooled and compressed.
Explanation:
The work done by the gas can be written as
and all the data is given in the problem, so
is the work necessary to compress the gas in the cylinder, wich is negative because the exterior is doing work on the gas.
Now, from first law of thermodynamics, we have that
<em>where is the internal energy difference,
is the calculated work, and
is the heat flow that we wish to know</em>, then
And the direction of the heat flow is outside of the gas, as it is being cooled and compressed.
Finally, it doesn't matter whether the gas is ideal or not, because we never use the Ideal Gas hypotesis, that , and
is constant.
The boat traveled from the dock north to the 200-meter marker in the bay in less than 5 minutes, giving the passengers several more hours to fish.
Explanation:
A boat traveling from the dock northward to a 200m mark in the bay in less than 5minutes giving the passengers several more hours to fish is a typical and best example of velocity description.
Velocity is the displacement of a body divided by the time taken.
Velocity =
Displacement is the distance covered in a specific direction. Time is duration of the travel.
Velocity is a vector quantity that has both magnitude and direction. This implies that the value of velocity is recorded with a directional attribute.
We can say velocity is the speed of a body in a given direction
Only the last option gives the displacement of the body and the duration it traveled.
