say 100 ppl are traveling along a wire, and a building that let's ppl go in one by one, does that mean there's a build up of ppl outside the entrance? that wouldn't make sense cause something will blow up.
Physics question about current?!?
if current passes through a resistor, current goes down (I=V/R), but doesn't that violate kirchhoffs current law, which states that current that goes in equals the current coming out? I'm so confused. also does voltage drop when current goes through a resistor?
hey mistabry i got the answer here:

it's not the exact same problem, but it's similar.
basically use F - T - Fs = 0. because the sum of the forces need to equal 0 since its not moving.
T = Fs, so just find Force.
The weight of the second...
omg yall are too vague! but it did give me clues on what to look for. spent like 10 hours trying to figure this problem out, but finally got it. Those in mr. todd's class don't need to thank me.
um i don't know how to post formulas cause it comes out all weird but, i found the equation in...
