AI Thread Summary
In a multiloop circuit with resistors in series, it is not mandatory to calculate the equivalent resistance (Req) before analyzing the circuit. Kirchhoff's Loop Rule can be applied directly to the circuit without simplifying it first. The discussion emphasizes that whether to find Req or not depends on personal preference and the complexity of the circuit. Both approaches yield valid results, allowing for flexibility in problem-solving strategies. Ultimately, the choice of method should align with the specific circuit's characteristics and the solver's comfort level.

Homework Statement



This is not an exact homework problem, but a question about a problem-solving strategy. In a multiloop circuit, when there are two resistors in series in a single loop that are not interrupted by junctions or emf sources, should I (or must I) find Req before analyzing the circuit?

Crude example:

|----R1----R2---|---V2--|
|xxxxxxxxxxxxx|xxxxxx|
|--------V1------|--R3---|

Sorry it's so ugly, x is dead space and the lines are wires. This kind of circuit could be much more complicated, but this is the basic concept.

Homework Equations



Kirchhoff's Loop Rule, 1/R1+1/R2 = 1/Req (in series)

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}...

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...
