AI Thread Summary
The discussion centers around the correctness of an electrical circuit calculation involving formulas for frequency, potential difference across components, and current. The user seeks validation for their use of the formula f = 1 / (2π√[L.C]) and the subsequent calculations for potential difference across a coil, capacitor, and resistor. There is a request for clarification on whether the calculations and formulas applied are accurate. Additionally, a broken link to a Flickr image is noted, which may contain relevant visual information. The thread emphasizes the need for accurate electrical circuit analysis.

Am i using correct formula?

Please see question at . . . . . .http://www.flickr.com/photos/3714455...60721/sizes/o/

(B) f = 1 / (2.pi. square root of [ L.C ] )

(C)

(1)P.d across coil = 2.pi.f. (0.32)

(2) P.d across capacitor = 2.pi.fr.(0.5 x 10^-6)

(3) P.d across resistor = 30v - (1) - (2)

(ii) Current = 30/60

Is this correct??

Thanks

Thread 'Variable mass system : water sprayed into a moving container'

Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...
