how does wind have energy?
1. it can change direction
2. it can do work
3. it moves through space as waves
4. it is electrically charged.

What is the relationship between the direction of motion of the balloon and the wind currents

Which describes increasing the efficiency of energy resource

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
