Zip Codes Are Not Based on Geography. ZIP Codes were created to expedite mail processing, not to identify neighborhoods or regions. Their boundaries are based on the logistical and transportation needs of the United States Postal Service and not on neighborhoods, watersheds, or community cohesion.
An electron is accelerated inside a parallel plate capacitor. The electron leaves the negative plate with a negligible initial velocity and then after the acceleration it hits the positive plate with a final velocity ?. The distance between the plates is 18.0 cm, and the voltage difference is 129 kV.
Best Answer: This is AC (Alternating Current) so it isn't positive and negative but hot and neutral. On a polarized plug, there is one wide blade and one narrow blade. The wide blade is neutral and the narrow blade is hot. The ribbed (white if there are colors) is neutral; the smooth wire (black if there are colors) is hot. So... hook the ribbed side to the wide blade (or white wire) and the smooth side to the narrow blade (or black wire). --------.
