uniform linear charges and plane charges and mastering physics?? I am completely stumped on this mastering physics problem, problem 22.34 (same as out of the university physics volume 3 11th edition book) and I cannot find any examples to compare to in my physics book and I have tried multiple...

Ok here is the problem A hollow spherical shell with mass 2.50kg rolls without slipping down a slope that makes an angle of 30.0 degrees with the horizontal. > Find the acceleration a_cm of the center of mass of the spherical shell. > Take the free-fall acceleration to be g=9.80m/s^2. > I...

hmm as far as home goes thinking abnout it in diagram parallel would allow one post to switch off while allowing flow still to go through another allowing one appliance to turn off while keeping other on in one circuit compared to series where you knock out one you knock out the rest...

so b*F*tan(pi-(theta)) ? I still don't understand I know if I do sin(pi-(theta)) Its opp over hyp so it would be parallel to b but I am not sure what trig woudl get it to go perp then

This section I don't understand at all... but the problem is What is the torque tau_B due to force F_vec about the point B? (B is the point at Cartesian coordinates (0, b), located a distance b from the origin along the y axis.) Express the torque about point B in terms of F, theta, phi, pi...

dont need help anymore heh got both answerss I needed I feel quite stupid now actually heh

Yeah I just got it before I read your post guess I was little stupid on that one heh.. but second one I still don't get what I am doing wrong?

2 mp problems that I sort of understnad but dont?? Edit: I figured out first problem... I was missing + pi/2 in the equation but still a little screwed up on second problem : Edit: Figured both of em out with help. thanks for the help

The momentum would be conserved wouldn't it? Well not completely though? Wouldnt a lot be lost because of the wall? I don't understand where you are pointing me with this? I know I have to treat x and y comp seperately but I don't truly know what teh heck an x and y component is in this prob...

First off let me say I am completely stumped. I don't remember teacher teaching this, and its definitely not in book(I went through it 3 or 4 times) and its not even the same book mastering physics uses... The Question is : What is the final angle that the ball's velocity vector makes with...
