That's the problem, I don't understand how they relate. Is there a conversion from Kelvin to Joules? Or do I just use 3K = 1380J - W?

Homework Statement When 1380 J of heat are added to one mole of an ideal monatomic gas, its temperature increases from 272 K to 275 K. Find the work done by the gas during this process. Homework Equations I assume \DeltaU = Q - W is the formula to use. But for some reason I'm just confused...

I think I got it. There would be more acceleration for the person pulling. Right?

I see, I forgot to differentiate which mass was which. There is an applied force of 10N, but no mass is used, how does that work?

T = ma and for the hanging block -T + mg = ma T = mg - ma plugging it into the first one: mg - ma = ma a = g/2 For case 2 we would have: T = ma -T + F_{applied} = ma T = F_{applied} - ma plugging in for the first 1 F_{applied} - ma = ma a = \frac{10}{2*m}...

Homework Statement A Modified Atwood's Machine has a 10 N cart on a frictionless, horizontal track with a 10 N hanging weight attached to a string connecting the two weights. A second track is set up with the hanging weight replaced by a person who can maintain a 10 N pull on the string (as...

PhanthomJay: Yeah, I guess the only information I could add is the trend line equation or the slope value. I guess I'll add that and hope it's good enough, thanks.

But the graph is for position vs time, which is linear. Therefor the Velocity vs. Time graph would have a slope of 0, making it constant velocity.

I am doing make-up questions from my General Physics test. This is pretty easy stuff, and I thought I answered correctly, but according to my teacher's comments on my paper it seems like I'm missing something. Homework Statement For the data provided, is the velocity for this object...
