Sean stirred 10 grams of sand into 50 mL of water and 10 grams of salt into 50 mL of water, then he let both mixtures sit for 10 minutes. Which of the following can Sean expect to observe after 10 minutes?

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?
