AI Thread Summary
An RLC circuit with an effective AC voltage of 170 V at 60 Hz consists of a 20.7 mH inductor, a 0.162 μF capacitor, and a 55.1-ohm resistor in series. To find the effective current, the formula I(rms) = I/sqrt(2) and I = emf/Z are used, with Z representing the impedance. The power factor is calculated using the formula power factor = R/Z. The discussion highlights the initial confusion about the formulas needed to solve the problem, but a helpful link was provided to clarify the concepts. Ultimately, the user was able to understand the calculations needed for the effective current, power factor, and power consumed in the circuit.

Thread 'Struggling to understand the concept of this question (ice cube in water optics question)'

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...

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}...
