“I Saw the Figure 5 in Gold” is an art piece painted by Charles Demuth‚ an American Artist born in Lancaster‚Pennsylvania from 1883-1935. This specific piece was painted in 1928 and is made of oil‚ graphite‚ ink‚ and uses gold leaf paint on paperboard. This art piece is encompassed of varying hues of red‚ yellow‚ orange and gray paint. The most important aspect of this piece is the number 5. The point of this is to pay homage to a poem by William Carlos Williams. In Williams poem‚ he writes about

horn because the styrofoam caused the speaker to move easily thus requiring a smaller magnet to drive the speaker. Next is the electrostatic flat panel speaker or ESL. The ESL uses to metal grids with a diaphragm constructed from a plastic sheet. Graphite is spread throughout those plastic pieces because it is electrically conductive. The grid act as electrodes. The diaphragm has a constant charge and a high audio signal which is produced by the grids. These speakers have a very poor bass response

Abstract Chemical reactions can be used to produce electricity and electricity can be used to cause chemical reactions through oxidation-reduction reactions. The first part of the experiment measures the standard electrode potentials of five various half cells against the Cu2+(1M)|Cu half cell. The last three half cells are prepared through electrolysis. The electrode potentials of all reactions are positive which means that they are spontaneous. There is a significant percent difference from the

property is what gives them their ability to easily conduct heat and electricity.There are sub-groups of metals called the alkali metals‚ alkaline earth metals‚ and transition metalsNon-metals: Bad conductor of heat and electricity (exception: Graphite‚ a form of carbon). Don’t have shining luster (Exception: Iodine). Dull appearance. May be solids‚ liquids‚ or gas at room temperature. Neither Malleable nor ductile. Most have low melting and boiling points (Exception: Carbon and some others)
