Car Battery Circuit: Current Through Starter & Dead Battery

AI Thread Summary
The discussion focuses on calculating the current through a starter motor and a dead battery when jumper cables are attached. The good battery is determined to supply 200A to the starter motor, while the dead battery contributes 14.5A. The calculations are based on Kirchhoff's Loop Law and Ohm's Law. The user expresses confusion about the next steps after finding these currents. Further assistance is requested to progress in solving the problem.

Homework Statement


Two parts:

With the jumper cables attached, how much current passes through the starter motor?

With the jumper cables attached, how much current passes through the dead battery?


Homework Equations


Ohm's Law and Kirchhoff's Laws


The Attempt at a Solution


Well I've already figured out that the good battery can supply the starter motor with a 200A current and the dead battery can provide it with a 14.5A current. I found both of these answers using Kirchhoff's Loop Law. I'm honestly lost from here though.

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}...
