Answer:

Explanation:
For this case we know the following info :
represent the initial volume
represent the final volume
We know that the pressure and volume are related with the following expression:

Where a is a constant given 
And we need to calculate the work associated to this process.
We have a compression, and by definition the work is defined with the following general expression:

If we replace the expression for P we got:

If we integrate we got:

Using the fundamental theorem of calculus we have:

And replacing the values we got:

Answer:
1. Graph C
2. Friction
Explanation:
1. The line on all of the graphs shown represents velocity. The formula for velocity is
where d is distance and t is time. Focusing on the first lap, the starting point on the graph should be the origin and the "ending" point should be (20, 3). These requirements eliminate graph A as an answer because its "end" is not (20, 3). During the break, the student does not move, so the slope of the line should be completely horizontal. The break lasted for 5 minutes, so the correct graph should have a horizontal line between the points (20, 3) and (25, 3). This requirement eliminates graph B and D because their break is either not long enough (B) or too long (D).
2. Friction slows down the movement of objects. When an object is rough, it produces more friction which causes the object to be slowed more. When an object is smooth, friction slows it less than it would for a rough object.
