nope. that's why i can't figure out anything besides the resistance. i don't even think the question has possible answer.- anonymous820

Solving Complex Circuits - Voltage & Current w/ Resistance
Homework Statement R=resistor determine the voltage across and the current through each resistor for the circuit. The Attempt at a Solution 1&2=parallel 1/50+1/25=3/50 --> 50/3=16.7 ohms 3&4=parallel 1/10+1/10=1/5 --> 5 ohms 5&6=series 5+10=15 ohms total resistance=36.7...- anonymous820

Another friction and inclined plane question.
there was no point in b. that was the dumbest question possible. I am so slow. its in equilibrium, so therefore, the sum of all the forces is 0, duh. wow. lol. yet. but i will be soon =) i don't quite understand what I am doing for question c. 211 N?- anonymous820

Another friction and inclined plane question.
oh yeah. and is d. right? i found the coefficient the same way i found the cofficient in the other problem about the skiing. except this time, they actually gave me real numbers i could work with.- anonymous820

Another friction and inclined plane question.
it tells you that the normal force and the Fy are equal to 325 N? then, the applied force is negative and Ff and Fx are negative? so then, Fx and the applied are equal? or Fx and Ff are equal? or Fx and Ff are equal to the applied? lol. ..no problem. i figured it was a much better set up...- anonymous820
