How to find volumetric rate sir? If I multiply it by density, i wiil get mass rate...

I still can't get the answer... :( Anyway, the book says its answer is 77 Ampere

\Delta \ KE = -\frac{1}{2}.m.(v_2^2-v_1^2)=-\frac{1}{2}.\rho.V.(7^2-12^2)=61.275V (V = Volume of air) \frac{\tau}{\epsilon} = \frac{N.B.I.A}{N.B.A. \omega} = \frac{I}{ \omega } \ \rightarrow \ \tau= \frac{\epsilon.I}{\omega}=\frac{P}{\omega} \tau=\frac{\Delta KE}{\omega.t} \ = \...

A 120-V generator is run by a windmill that has blades 2.0 m long. The wind, moving at 12 m/s, is slowed to 7.0 m/s after passing the windmill. The density of air is 1.29 kg/m3. If the system has no losses, what is the largest current the generator can produce? (Hint : How much energy does the...

Anyone? :(

Ok, thanks sir for the help... :)

Thanks for the reply Which one is true? :confused:

Here it is...

Yes, i have had velocity. But the time is my problem, i still can't get the variable t

[PLAIN]http://img204.imageshack.us/img204/9204/fisika.jpg How much time will elapse until this particle arrive at point O? Edit : that force is F = kx-2 not kx2 Thanks

I have tried it all over, and still can't solve it, please if anyone here know the right equation for acceleration and net force on mass C help me...

Hehe... Thanks Iclaudius... :) Hmmm... So, what is the right equation for the acceleration? And, is my equation for mass C true?

Hi tiny-tim, thanks for your reply! But I'm still stuck :( Here's my complete paper work http://img850.imageshack.us/img850/7237/unledpv.jpg Phewww... And you know what, it is still wrong :cry:
