    Photoelectric effect and maximum kinetic energy

    thank you very much for that link explained a lot, and no its not school-type work, its simply personal leisure.

    Photoelectric effect and maximum kinetic energy

    so then just say the stopping potential was 1.6 volts, how would you go on calculating W.

    Photoelectric effect and maximum kinetic energy

    Oh very sorry i was not given the kinetic energy, however i knew the mass of the particle. can't remember whether it was a photon or electron. In terms of calculating the work function for this particular experiment, is it the absorbed photons we need to consider in determining the work...

    Photoelectric effect and maximum kinetic energy

    Hey guys, assume that i performed and experiment to measure the maximum kinetic energy of electrons released due to the photoelectric effect due to light falling on a metal target (i.e. Sodium). KE = hf - W (where W = work function, f = frequency and h = Planck constant) since KE = 1/2...

    Graph of Magnetic Flux for DC Motor from 0-360

    Hey guys, just a quick question, what would a graph from 0 < x < 360 for magnetic flux look like for a DC motor, where the coils initial position is parallel to the magnetic field.

    Is Anti-Gravity Possible? Theoretical Analysis and Extreme Conditions Explained

    Hello i was just curious on whether anti-gravity, theoretically speaking is a poissibility. Through Einstein's models of general relativity he explained that gravity wasn't a force, but a direct result of the geometry of space itself. Therefore making the possibility of anti-gravity highly...

    How to Calculate Time Required for 11 Light Years @ 0.9c

    ohh :) good thank you very much tiny-tim for your help :D

    How to Calculate Time Required for 11 Light Years @ 0.9c

    Ok for arguments sake let's say it was 11 light years in his frame of reference :) your starting to scare me that there's more to the question than I anticipated :s lol that's ok

    How to Calculate Time Required for 11 Light Years @ 0.9c

    I was just quoting the exact question that I was given In a test :s however since the passenger is in the same frame of reference (inertial frame if reference) to the spacecraft you can simply use the time = distance over speed formula ?

    How to Calculate Time Required for 11 Light Years @ 0.9c

    You are in a spacecraft that is traveling at 0.9c (according to the passenger), and you want to get to a planet that is 11 light years away. How long will it take to get to the planet ? This may seem like a simple problem but it's been bugging me. I answered this question by using the simple...
