AI Thread Summary
The discussion focuses on applying Kirchhoff's Rule to determine the current through resistors in a circuit. Participants are asked to verify the setup of the calculations without needing to check the actual values. There is a light-hearted comment about the legibility of handwriting, indicating a casual tone among contributors. The main goal is to ensure the correct application of the formula V=IR in the context of the circuit analysis. Overall, the thread emphasizes collaboration in solving circuit problems.

Find The current through each of the resistors (see graphics)



V=IR


I would like for someone to please check my work to see if I have set it up correctly. No need to check actual values. Thank you!

I was going to but I'm afraid I was put off by your hand writing. It's almost as bad as mine :-)
 
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}...
I was thinking using 2 purple mattress samples, and taping them together, I do want other ideas though, the main guidelines are; Must have a volume LESS than 1600 cubic centimeters, and CAN'T exceed 25 cm in ANY direction. Must be LESS than 1 kg. NO parachutes. NO glue or Tape can touch the egg. MUST be able to take egg out in less than 1 minute. Grade A large eggs will be used.
