    B Ideas to protect the Earth from possible asteroid impacts

    There is another idea which I think was in the movie Armageddon from '98. Instead of blowing up a nuke on the surface, you drill into it and blow it up from the inside. This way you split the asteroid and then the larger pieces will be pushed away from Earth without changing the momentum of the...

    Calc Electron & Hole Concen in Silicon at 300K

    Check your electron concentration equation again, you may be missing a parenthesis inside the square root.

    Use the data to construct a graph etc.

    Think about what the tangent gives you. What is the rise/run of the tangent line telling you about the position of the car vs time?

    Percentage energy loss (mechanical energy) problem

    You shouldn't divide by the other work, if your equation above is correct you should subtract mgh(0) to get W alone

    What are the main sections in PF and how can they help in learning science?

    My name is Nathan and I am a recent college graduate with a Bachelor's in Physics! I joined this site about six months ago but am just now getting around to the introduction. I enjoy playing soccer (have been playing on various competitive teams nearly my entire life) and I enjoy the outdoors...

    What actually makes a magnetic field?

    I have tried looking this question up and I hope I am posting this question in the correct spot. I have read a little about photon clouds which surround electrons in a magnet but since I see myself as a very visual learner I think I am trying to think about this question as if something is...

    Determining the magnetic force on an electron

    You did use the RHR correctly, but when you say that the magnetic force on the electron is up [N], this is not correct. When I use the RHR I use my pointer finger to point in the direction of velocity, (since it is the first term in the cross product), then my middle finger points in the...
