It's the work that is done on the gas I believe.

Homework Statement An ideal gas is enclosed in a cylinder that has a movable piston on top. The piston has a mass m and an area A and is free to slide up and down, keeping the pressure of the gas constant. How much work is done on the gas as the temperature of n mol of the gas is raised...

Sorry about the θ! Well, since I got the answer wrong when I tried to say that the upward force was simply the Fn, I tried to break it up into components. I thought that I should look at the m*g*cos(θ) as the x component and m*g*sin(θ) as the y component. So, I tried to use arctan(y/x) to get...

Homework Statement Your 3.10 kg physics book is next to you on the horizontal seat of your car. The coefficient of static friction between the book and the seat is 0.640, and the coefficient of kinetic friction is 0.540. Suppose you are traveling at 79.2 km/h = 22.0 m/s and brake at a constant...
