Ok so I'm studying for my final tomorrow (AHH! I know!) and I'm going over gas laws. I have a problem giving me the starting pressure and temp and the final pressure, and its looking for the final temp. The volume is assumed to be constant. Now i know what to do if it was consant temp or...

Yeah that's what I was assuming, however as you can see its not included with the problem. What forumla can I use to calculate it using the information I'm given? :confused:

Ok, I've been working on this and I think I have some progress, and I'm so close but I just seem to be missing a key point or something. Using Poiseuille's Law: P1-P2=(8QnL)/(pi*R^4). Now to find n , the coefficient of viscoscity, i have to use the equation : F(visc)=n *(Av)/D...

Hey I've been working on this pressure problem, and I am really stumped. We just started fluids, and I'm not really sure where to start. If someone could help me or point me in the right direction, that'd be great. Thanks! Heres the problem: A straight horizontal garden hose 43.0 m long...

Hey I've been having trouble with this impulse problem, in fact I don't even seem to know where to start. My prof didn't even cover any impulse problems in class and then expects us to do one for homework. :rolleyes: But anyways, any help would be appreciated, I'm sure there's someone who can...

Thanks! :biggrin:

Hey guys thanks for the help on the last problem, I just had one more that I was trying to get finished studying for this big exam coming up: A block with mass m = 13.0 kg slides down an inclined plane of slope angle 32.8 ° with a constant velocity. It is then projected up the same plane...

I'll see what kind of numbers I get with that, thanks! Edit: Hey looks like that worked out, thanks man! :biggrin:

Ok I've been working on this problem for a while, and I'm kinda new to physics, so bear with me. So here it is: Heres the picture of the problem: A frictionless pulley with zero mass is attached to the ceiling, in a gravity field of 9.81 m/s2. Mass M2=0.150 kg is being accelerated...
