    Minumum electron energy and microscopes

    p=sqrt(2mK) So, do I use that equation in conjunction with DeBroglie's? λ = h/p This one is used for electrons, right?

    Minumum electron energy and microscopes

    Homework Statement The highest achievable resolving power of a microscope is limited only by the wavelength used; that is, the smallest item that can be distinguished has dimensions about equal to the wavelength. Suppose one wishes to "see" inside an atom. Assuming the atom to have a diameter...

    Rank Resistances: A, B, C, A+B, B+C, A+B+C

    Homework Statement The figure below shows cross sections through three long square conductors of the same length and material, with square cross sections of edge lengths as shown. Conductor B fits snugly within conductor A, and conductor C fits snugly within conductor B. Rank the following...

    Calculating Arrow Speed with Doubled Force | Newton's Law Problem

    F = ma If the force doubled, then the acceleration must double, because the mass definitely can't double xD So, that means the new acceleration is twice the initial acceleration. This doesn't mean the new velocity is twice the old velocity. First, let's find the initial acceleration. vf = vi +...
