Does this give us... 1) Q2/C - ICRC - V = 0 2) ILRL - (L * diL/dt) - V = 0 Or am I just completely off?

Quick Question... Given: Can I still use the general impedance equation for parallel RLC circuits even though the resistors are not in parallel with the other components? Substituting the two resistors for a single resistor with the equivalency resistance?

The ball (marble) would start at the bottom of the ramp and get "shot" up towards the top of the ramp. Huh, I had always just assumed that the oil would reduce friction, I didn't think it would actually increase it. This sounds like a solid plan. One last thing, the goal of the entire...

I'm working on a simple question involving finding the initial velocity of a ball as it is launched from a shooter and goes up a ramp. The ball is lathered in oil to reduce friction and create a marking for easily measurable travel distances. From there, you can gather several trials of data...

Hey guys, We skimmed a chapter on differential eqns in my semester 2 calculus class and we have a worksheet to fill out. I'm having trouble setting up the last 3 problems in this sheet. http://dl.dropbox.com/u/85600/DIFF_HW.PDF" I'm pretty sure It's all just algebraic manipulation to...

Homework Statement For what values of K is the following integral improper? \int\stackrel{K}{0}x^2 / (x^2-19x+90) dxI'm stuck on this question. I understand mechanically, that the integration require partial fraction decomp, which results in -9ln(x-9) (from 0 to K) + 10ln(x-10) (from 0 to...

but don't we have to account for 3 more 'r's if we do this since du = r^3 dr?

#1 Homework Statement \int r^4 ( ln (r) ) drHomework Equations Infinity algebra and Calc related formulae..The Attempt at a Solution Not sure even where to start here.. I'm thinking a u-substitution, letting u = r^3 so that I can deal with the two left over r's, but I don't think that it would...
