. Homework Statement A metal bar is free to slide without friction along two parallel metal rails. The circuit is completed by a battery. (conducting bars are in the x direction, left side of drawing the conducitn bars are connected by a battery, the right side is where the metal bar is) If...

tim i love u, ur great, a genius i should say, i appreciate the help

ok the potential difference between the two points a and b, is the sum of the potential drops between them, therefore, there is a 3 volt drop and a 6 volt drop, which adds to 9, therefore the ptential difference is 9 V is that correct?

wait, how would i do that, would i just make a half of a loop then or what, the best i could think of is dividing the loop in two part and solving for1 part, i said that E2-R2I2=I3R3 + I2R4 Solving for either side gives 9 V, is that the correct answer, but most importantly the correct...

loop 2 is E1-I1R1 +I2R2-E2 +I2R4=0, but i ddin't use it

When i applied kirchnoffs rules for the diagram i get, Loop 1 being- the left side loop 2 being- being the whole thing loop 3 being the the rights side loop 1= E1-I1R1-I3R3=0 I solved this one for I1 and got I1=(E1-I3R3)/R1 and got I1=3.0A for loop 3 i got E2-I2R2-I3R3-I2R4=0 i...

here is a picture, this should help hopefully im tryin to find v at A by v at b

Homework Statement The problems tells me to determine the potential difference between between two points. I alrady know that the potential of one point is zero. The problem I am having is that the cirucit has two batteries. I do not have a question so i will describe it, it hsould be easy...

A while ago I did a lab experiment using an inertial balance (oscillating horizontally) to calculate the inertial and gravitational mass of an unkown object. Following, the inertial balance was clamped under the edge of the bench with the balance extending downward. My teacher said that the...
