Kinematics:Question 2 Correct
A projectile is thrown directly upward at a velocity of 12.0 m/s.
What is the projectile's maximum height from its starting point
before it begins to fall back toward Earth? (g = 9.8 m/s)

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
