A Carnot engine uses a hot reservoir consisting of a large amount of boiling water and a cold reservoir consisting of a large tub of ice and water. When 6600 J of heat is put into the engine and the engine produces work, how many kilograms of ice in the tub are melted due to the heat delivered...

my temperature for this question is 37 degrees Celsius...and i got deltaL to be 0.001066...i'm still not quite sure what to do with that

wait so, (a) (mwi)/F ? (b) (mw)/F ? wouldnt you have to factor in uk?

I now understand the wording for (a)...thanks!

yea i got 0.40 m for both a and c too...awesome!

Thank you for your help! So, (a) the spool can't be completely motionless due to gravity because even though you are not applying a force by pulling on the string gravity is still acting on the spool down the incline (b) this is possible because you can "pull hard enough to counteract the...

Hi...ok so i just need help to make sure I'm understanding the concepts and my answers are correct. I think i get it but i just want to make sure. Thanks! A spool of mass m has a string wrapped around its axle, with the string coming away from the underside of the spool. The spool is on a...

ok so part (d): Use your value from (c) and one or more constant-acceleration equations to find h, the distance the block has dropped when its speed reaches 2.0 m/s. Does it agree with your answer from (a)? so i used w = wi + alpha*t t = w/alpha t = 4/5 = 0.8 sec then i plugged that into x =...

so then you should get a = (2mg)/(M+2m) and when you solve for a you get 5m/s^2, right?

and then what?
