1 The diagram below shows forces acting on an airplane. The airplane is accelerating to the
left at a constant height above the ground.
Lift
Based on the diagram, how do you explain
that the plane is accelerating to the left at a
constant height?
Thrust
Drag
A. Because the lift is equal to the drag.
B. Because the lift is less than the
weight
Weight
C. Because the thrust is equal to the
drag.
D. Because the thrust is greater than the
drag.

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
