    A few quick conceptual questions about capacitators and dielectrics

    Hmm okay, thanks for the responses! My teacher wasn't too clear with wording the question, so I'm not sure if isolated means no voltage is being supplied... So if a battery was supplying voltage, the voltage would stay the same but the charge would increase to make potential stay the same...

    A few quick conceptual questions about capacitators and dielectrics

    Homework Statement So my question is conceptual. I am trying to figure out in what direction an electron will move if it starts between two plates of a parallel plate capacitator. One of the plates is at 0V and the other is at 50V. Also, would placing a dielectric in a charged, isolated...

    Magnetic Field at center of circle on rectangular circuit

    Homework Statement A circuit consists of 7 sections of wire. The figure looks like a rectangle of length 9cm and width 5cm with a circle of diameter 3 cm cutting right through the middle of one of the 9cm sides so that the two sides of the circle are in parallel. Each of the sections of wire...

    Electric field and potential of 2 point charges

    Homework Statement A -2 μC charge and a 10μC charge are separated by 15.0cm. At what point is the electric field zero? At what point is the electric potential zero? Homework Equations E=(kq1/r1^2)+(kq2/r2^2) V=kq1/r1 + kq2/r2 The Attempt at a Solution My main problem is with...

    Pendulum Amplitude and phase constant

    Wow, it's really that simple? Thanks, I really understand this a lot better. So to find phi, do I use θ(0)=Acos(phi), plug in the initial angle it was pulled back for the theta0, and solve for phi?

    Pendulum Amplitude and phase constant

    Homework Statement A simple pendulum of length 1m with bob mass 125g is pulled 15 degrees to the right and released at t=0.What are the phase constant and amplitude? Homework Equations θ(t)=Acos(ζt+phi) ---> my teacher gave us a weird symbol that I've never seen before, it has always...
