The three classes of rocks are sedimentary, metamorphic, and igneous. how are rocks classified into one of these three groups? a. according to the type of minerals present in the rock b. according to how many times they have been through the rock cycle c. according to the method of their formation d. according to the amount of weathering they have endured rese

Aparticle of mass m is placed in a one-dimensional box of length l. the box is so small that the particle’s motion is relativistic, so that e p2/2m is not valid. (a) derive an expression for the energy levels of the particle using the relativistic energy–momentum relation and the quantization of momentum that derives from connement. (b) if the particle is an electron in a box of length l 1.00 1012 m, nd its lowest possible kinetic energy. by what percent is the nonrelativistic formula for the energy in error?
