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.
