Homework Statement A 1-liter aluminum container at 20oC is filled with 0.975 liters of mercury at 20oC. If both the container and the mercury are heated, at what final temperature will the mercury completely fill the container? αAl = 24 × 10-6 (Cº)-1; βHg = 1.82×10-4 (°C)-1 Any help on...

Homework Statement Hi all, Im kinda stuck on how to solve for V at this point...could use some help. thanks 80.36= 2.05V2 + V2/.0025

thanks for the help. much appreciated

I = 1/2mr2

ok..found an equation...guess I need to organize equations better..seems to be my big problems. t=mr2α that should do it I think..anyone like to confirm? thanks

Homework Statement See attached Homework Equations Ok..Im having difficulty with this problem. I don't see what m has to do with angular accerleration. The Attempt at a Solution I believe the equation to use for this is a=rα ? I just can't get there..any help would be great...

Hi all, Just wondering if anyone knows of a good webstite for practice problems. I ve looked around and most sites have one or two problems. Maybe its me but I learn better by doing lots of problems over and over. I am taking general physics and am now working on momentum, 1 d collisions...

Thanks for the help Simon

Thanks for the response. So what your saying is the rubber bands absorbed the momentum? So the momentum was preserved in the rubber bands? Since they did go twang (stretch)? I am guessing not much heat was generated during the twang. So energy was lost during the stretch(deformation)?

Homework Statement Hello, I have a question about a one dimensional collision lab done in class. We set up an air rail with two gliders..one at each end. Each glider had a rubber band bumper. We pushed them towards each other and they hit each other and bounced back some. We collected...

Thanks for your help. Much appreciated

Thanks for the reply.. For question one..I still don't understand why work will be the same. If you add friction work should increase? I attached a free body showing my work.

Hi All, I am a real noob with physics...not my best topic. Trying to do the best I can. Just want to run my noob logic past some people much better at physics than me. We did a lab in class and I think I have the correct answers but just want some confirmation. Homework Statement We...
