    Electrons in a beam of televison tube

    Ive got a question where I have to find the acceleration of a single electron due to the magnetic field. Now here is what I did. I tired to find Velocity using KE = .5mv^2. Solving for v. Then knowing that F=qvB and F=ma I made the equation qvb/m=a. But I can't get this to work. Is there some...

    How Much Heat is Needed to Raise the Temperature of a House?

    I have a question I'm trying to but I don't really know where to start. It is kind of an add-on to a previous question that I got pretty easliy. This is the first question: The answer to that was 156000 W. Now the second question asks how much heat must be supplied to raise the temperature and...

    Can someone help me find the equivalent resistance

    OK I still can't get it I have R3/R4 in parallel. Then I took that in series with R2. Then I took that in series with R6//R5. Then all of that in series with R7. And finally that in parallel with R1. Does all that sound right?

    Can someone help me find the equivalent resistance

    For this question I am pretty sure I am doing everything right but I just can't get the right answer. Diagram below. This is the question. Find the equivalent resistance of the circuit shown in the diagram, where R1 = 3 Ω, R2 = 2 Ω, R3 = 4 Ω, R4 = 1 Ω, R5 = 1 Ω, R6 = 2 Ω, and R7 = 2 Ω. What I...

    How Do You Calculate Current in R1 Using Kirchhoff's Rules?

    Using Kirchhoff's rules, calculate the current in R1 with the directions indicated in the figure below. Assume that R1 = 1.00 kΩ, R2 = 3.00 kΩ, R3 = 5.00 kΩ, E1 = 60.0 V, E2 = 50.0 V and E3 = 65.0 V (Diargram in attachment). This problem has kind of stumped me. I tried setting up three...

    Physics true/false questions v. isolated parallel plates

    Which of the statements below are true for two oppositely charged, isolated parallel plates? (C is the capacitance, U is the stored energy, +Q and -Q are the charges on the plates.) Note: isolated plates can not lose their charge. (Enter ALL correct statements, e.g., BCD) A) When the...

    Find the charge on each capacitor

    yeah I've got that all figured out, its calculating it from there that I am having problems with.

    Find the charge on each capacitor

    I'm trying to do this problem, its is posted below, where I have a circuit with four capacitors and I have to determine the charge on each one. I've been trying to follow an example from my textbook but that's not really helping me. I've been also trying to break it down with capacitors in...
