    Angle between B-Field and X-axis

    If my y components cancel out and my x-components add up, then will my angle be 359?

    Angle between B-Field and X-axis

    Homework Statement Two long horizontal straight parallel wires are 3.18 cm apart and each carries a current of 9.25 A in the directions shown in the above figure. What is the magnitude of the B-field at point P, which is at a perpendicular distance of 2.25 cm from both wires? Homework...

    Algebraic Sums of Currents/EMFs in Junctions/Closed Loops

    Thanks for the help! I did the lab today, my value for the voltage didn't add up to zero, because the errors, but it was very close to it.

    Algebraic Sums of Currents/EMFs in Junctions/Closed Loops

    I thought so too, because we haven't learn the Kirchhoff's laws yet in class, but we have to do this for a lab. I think from the diagram, there seems to have no problems that would violate the Kirchhoff laws, but then during the performance of the actual experiment I think there may be some...

    Algebraic Sums of Currents/EMFs in Junctions/Closed Loops

    1. What causes the algebraic sum of the currents (signs included) flowing into each of the four junctions NOT equal to zero? 2. What causes the algebraic sum of the EMFs in each closed loop NOT equal to the algebraic sum of all the IR drops in each loop?For the first question, I thought that...

    What is the charge density of the wire?

    Thank you so much! I'm kind of getting this now, I'll go try it again.

    What is the charge density of the wire?

    1. Consider a long charged straight wire that lies fixed and a particle of charge +2e and mass 6.70E-27 kg. When the particle is at a distance 1.61 cm from the wire it has a speed 2.20E+5 m/s, going away from the wire. When it is at a new distance of 4.01 cm, its speed is 4.00E+6 m/s...

    How Do I Find the Coefficient of Friction Using Potential Energy?

    Hi, I really need help with my homework! I had a home work, it is like: I have a data table, that has Initial Position: 1.652m from the sensor Final Position: 0.977m from the sensor Initial Velocity: 0.003m/s Final Position: 1.366m/s Angle: 27 degrees g = -9.8m/s^2 U represent...
