nope i don't know what root-mean-square:S and my bad for the omega thing:P.. can u please show me how to solve it?

Can you rephrase what you just said please. i actually didnt understand. wat's rms? and what do u mean by have an omega.. can u re-explain please:S

A resistor draws a current i=8sinwt at a voltage of v=200sinwt. Calculate the average power dissipated in the resistor. What i did is p=ui = 1600sin^2 (wt) and i got stuck:P i don't think it's the right equation.. the answer should be 800W .. and that's nothing like it. Could someone help me ?

anyways if someone is willing to help just do please. and don't ask to add my work.. because I've already told u wat i did..

nevermind.. thnks for the help ...

man, I've been working all day long yesterday with the problem. I've already told you i used kvl and kcl on the nodes and nothing worked, i tried changing the voltage source into a current source and still it didnt work.. i tried finding equivalent resistors .. and still .. the same thing, I am...

come on someone help:S

Can someone please help me with this problem?? I tried kcl, kvl, and nothing is working... the voltage across the 6k ohm resistor should be equal to 6 volts! but I am never able to get this answer. please help problem: Determine the voltage across the resister with 6 k(ohms)..

can someone post the solution, i know its an old post but now i need the answer:) i have the same question in my year.. I am studying cce too ! can someone help?

yes|-) .. now can someone help me please^o)?

sigma Fext= M.a Newton's second law i think:P .. and u place the forces.. that's how i did it.

i did it and got a: 137.17 n b: 57.5 n c: -22n but I am pretty sure they're wrong:P

A 53 kg skier skis directly down a frictionless slope angled at 15° to the horizontal. Choose the positive direction of the x-axis to be downhill along the slope. A wind force with component Fx acts on the skier. What is Fx if the magnitude of the skier's velocity is (a) constant, (b) increasing...
