    Find the Driving frequency and phase angle for this R-C phasor problem

    It does! Thanks. so now i found the frequency and the angular frequency. any word on the phase angle or current amplitude?

    Find the Driving frequency and phase angle for this R-C phasor problem

    Do you know what the equation I would need for that is?

    Find the Driving frequency and phase angle for this R-C phasor problem

    Using the givens I found ωd=862 rad/s, and with some help I got tanϕ=-1 and Z=56.5685 ohms. But I can't figure out any of the other variables. I'm not even exactly sure what "driving frequency" is and I can't find an equation for it.

    Find the Velocity given Magnetic field and Magnetic Force

    I've been using ##B_y## as .0229 this whole time! no wonder none of the math made sense. Okay so I made 2 mistakes in my last one. The first was that I had .0229 as positive and the second was that I wrote in the value of ##B_x## where I should have put in the value for ##B_z##. I got ##v_y## as...

    Find the Velocity given Magnetic field and Magnetic Force

    so that's ## 4.22e-17 = 1.6e-19(.0137v_y - 38.472) ## multiply both sides by 1.6e-19 and you get ## 263.75 = .0137v_y - 38.472 ## add 38.472 to both sides and divdie by .0137 and you get ## v_y ## = 22060. Then you relate ## v_y ## to ##v_x## with that means that ## v_x= .598253v_y## and...

    Find the Velocity given Magnetic field and Magnetic Force

    I just don't really know how I would relate the two of them outside of how I'm using them to try to get the cross product, and that isn't working. Sorry.

    Find the Velocity given Magnetic field and Magnetic Force

    I can put ## .02192 v_y-.03664 v_x=0 ## that means ## .02192 v_y=.03664 v_x ## and therefore ## v_y=1.67153 v_x ## which obviously doesn't work for the numbers got because my ## v_y ## was negative and not 1.67153 times my ## v_x ## value So we definitely know I'm wrong, but I already knew that

    Finding the Current in a Resistor in a Closed Circuit

    1. Homework Statement The ideal battery in Figure (a) has emf = 7.7 V. Plot 1 in Figure (b) gives the electric potential difference V that can appear across resistor 1 of the circuit versus the current i in that resistor. The scale of the V axis is set by Vs = 18.9 V, and the scale of the i...

    Yup that worked. Thanks to everyone c:

    Calculate Net Charge Contained by the Cube

    What do you get when you try to do it that way? I'm really not very good at calc so that wouldn't be my go to.

    Well I thought it could, but now I'm nervous.

    Calculate Net Charge Contained by the Cube

    Did you get 24.781? I might have just took the original 83 number and flipped the sign. alright 24.7808+29.2864=54.0672 54.0672*8.85e-12 is 4.78495e-10C

    Calculate Net Charge Contained by the Cube

    okay so x is heading backwards into the negative direction. so the back face should be (1.65*-3.2+2.86)(cos 180deg)(10.24) = 83.3536 the total net flux is then 83.3536+29.2864 = 112.64 112.64*8.85e-12= 9.96864e-10C for my net charge? That doesn't seem like it works either
