Theoretically only, would a capacitor of infinite capacitance be considered an open circuit? What would it be used for in application if it did exist? The reason I am asking is because I have a homework problem where it is used with a JFET transistor in a circuit. If I can't solve the...

i don't know where you got velocity from... (might be something but i can't remember learning anything on it to do with this) and i can't seem to manage to relate the question the the image.. if you hold your palm flat down on a table top and have your thumb at a rightangle with all your...

a response in your method =p http://img96.imageshack.us/img96/1745/sresponsewm5.jpg

i would do integration by parts on the 1/x and the tan(x) then work from there. probably let tan(x) equal sin(x)/cos(x) and use substitution integration to solve that part then when you've solved the integration, sub in infinity and just logic it out from there i guess. sorry if its...

Homework Statement someone asked the ellipsiod problem before and i didnt under stand anythign in the repsonces >< but i had already gotten this far that my equation (simplified) is cos(theta)*sqrt[cos^2(theta) - (x^2)/(a^2)] i need to integrate this equation with respect to d(theta)...

M a s s - s p r i n g - d a m p e r - s y s t e m. (sorry about the random apostrophe's in some of the writing, i don't want someone to just google and take my working ><. i don't know if the apostrophe thing works though...) i have two different methods but i don't think either is right...

I'm still not making any progress on that problem. =\ @carbz: I've learned trig already, I'm studying in Uni right now (but like you said, there's not enough info to use trig). The frustrating part is that the problem comes out of a grade 10 book and I'm having so much trouble with it. I...

19 minutes ^^; Wrote down the clues twice each to remember them (the second time around I slightly categorized them to make them easier to find), then drew a table of 5x5 and filled it out. >< I didnt even realize when I finished that one of the slots was still missing a pet till I read here...

Thanks for the responces ^^ I'm glad to know I'm not the only one who thinks the question is really strange. =] I took another look at the original question and it's the same. The angle b forms on the radius within the circle and not on the circumference, the drawing was given in the...

grade 10, angle problem (geometry). Homework Statement find values of angles a, b and c in order http://img151.imageshack.us/img151/4662/trigproblemyn1.th.jpg the two lines withthe arrows drawn on them are parallel the center is at where the 94 degree angle forms Homework Equations...

its a four part question but the first part has me stuck: the question: A particle of mass m is accelerated from rest by a constant force F along a straight line for a duration of time t. Use relativistic mechanics unless explicitly stated otherwise. Also remember that the definitions of...

oh I am done. i was just getting some reassurance for my method i used. (thus why i didnt post this into the homework forum)

@jpr0: thanks for checking yeah, i figured there would have been a much easier way to get this done but i couldn't find one. how else could it be done? was that last line supposed to be 26 and 24 instead of the 25 and 23 (respectively) in that case should i have stopped at instead of...

this is the problem and I've worked for mostof it, but I am not sure I've got the right way to go about it, or if the ansewr i have found it right. here, I am using the method for finding the vector equation given the plane 2x + 6y + z = 6 intersects the paraboloid z = x^2 + y^2, find and...

just curious. say you breathed in a heap right before entering a vaccuum. would your lungs expand enough to cause bodily damage? because i would assume that something in your chest (particularly your lungs =p) would burst, leading to death. because i can't remember where i heard it but...
