Check all that apply. If the wave function for a system is a superposition wave function, the wave function of the system cannot be determined. If hair color were a quantum mechanical observable, you would not have a hair color until you looked in the mirror or someone else looked at you. Eigenvalues of quantum mechanical operators can be complex numbers. Probability plays a role in the outcome of both classical and quantum mechanical experiments.

The edge of a cube was found to be 30 cm with a possible error in measurement of 0.4 cm. use differentials to estimate the maximum possible error, relative error, and percentage error in computing the volume of the cube and the surface area of the cube. (round your answers to four decimal places.) (a) the volume of the cube maximum possible error cm3 relative error percentage error % (b) the surface area of the cube maximum possible error cm2 relative error percentage error %
