What is the acceleration of this object? the object's mass is 60 kg. box with dot in center. short arrow up, longer arrow down. up arrow labeled f sub air equals 400 n. down arrow labeled f sub grav equals 600n. 0 m/s2 3.3 m/s2 6.7 m/s2 10 m/s2

How would a small bar magnet be oriented when placed at position x?

Positive ions differ from neutral atoms in that

An electron is trapped at a defect in a crystal. the defect may be modeled as a one-dimensional, rigid-walled box of width 1.00 nm. (a) sketch the wavefunctions and probability densities for the n 1 and n 2 states. (b) for the n 1 state, nd the probability of nding the electron between x1 0.15 nm and x2 0.35 nm, where x 0 is the left side of the box. (c) repeat (b) for the n 2 state. (d) calculate the energies in electron volts of the n 1 and n 2 states
