| 1. | This random motion of the surface gives rise to Alfv�n waves.
|
| 2. | Using a middle-grade Scotch-brite pad, make a random motion to buff out the copper.
|
| 3. | This net electron motion is usually much slower than the normally occurring random motion.
|
| 4. | Such random motion is visible under ultramicroscopes and for bigger particles even under ordinary microscopes.
|
| 5. | Start with a gas with absolutely no non-random motion.
|
| 6. | Electrons have random motion instead of well-defined circular motion.
|
| 7. | Gas molecules are in constant random motion, and are continually bouncing off of each other.
|
| 8. | That process is due to random motion of molecules.
|
| 9. | At room temperature, the average speed of these random motions is 10 6 metres per second.
|
| 10. | The microscopic explanation for this is based in kinetic theory and the random motion of molecules.
