    How Does a Two Atoms Basis Lattice Act Independently?

    Homework Statement For a lattice with a two atoms basis, the two dispersion relations valid for Ka = ±∏ w2 = 2C/M2 and w2 = 2C/M1 Show that under these conditions the lattice acts as two independent lattices (one lattice per each atom) with one of the lattices moving while the other is...

    Nucleophiles vs Bases: Understanding Strong/Weak Reactions

    Yeah I'm still confused on how to differentiate the two. I know both bases and nucleophiles donate an electron pair to the electrophile, but that's as far as I am right now.

    Nucleophiles vs Bases: Understanding Strong/Weak Reactions

    I am going through Sn1, E1, Sn2, E2 reactions and I'm trying to figure out if the reaction involves a nucleophile (strong/weak) or a base (strong/weak). I understand that you can differentiate nucleophiles and bases by their pKa value but that doesn't quite help me out, since I'm not given...

    Graduate Infinite Well Problem - Time Independent Schrodinger's Equation

    I'm currently taking a Semiconductor class and we're talking about Schrödinger's Wave Equation, specifically the 1 dimensional time independent form. We were looking at the infinite potential well model: And we divided the graph into 3 different regions: first being the left (or...

    Calculating Flux through a Sphere using Divergence Theorem

    That is the million dollar question. Thank you very much my friend.

    Calculating Flux through a Sphere using Divergence Theorem

    That is a good idea, but I still didn't come out with the right answer.

    I'm sorry, I meant the x and y planes, not the z and y planes.

    Homework Statement A 1125 N force F is supported by cable AD and by struts AB and AC as shown. If the struts can transmit only axial tensile or compressive forces, determine the forces in the struts and the tension in the cable. a = 6 m b = 1 m c = 4 m d = 6 m f = 2 m...

    Integrating to find Volume (different from the other guy)

    Ok so I'm doing my online homework and I came across this problem: "Find the volume of the solid obtained by rotating the region bounded by the given curves about the specified line. y=11, y=x+28/x about x=-4" So I attempted to...
