The Study of Akali Metal Contamination in Road Side Soil The Study of Akali Metal Contamination in Road Side Soil IL 3; Experiment 1 October 31, 1996 Abstract Six soil samples were taken from a roadside that was expected to exhibit characteristic of road salt contamination. This contamination is characterized by the presence of magnesium, calcium and sodium. The relationship between akali metal concentration and distance from the pavement was examined and determined to be nonexistent. Additiona

Thomson demonstrated that the beam of glowing matter in a cathode-ray tube was not made of light waves, as the almost unanimous opinion of German physicists held. Rather, cathode rays were negatively charged particles boiling off the negative cathode and attracted to the positive anode. These particles could be deflected by an electric field and bent into curved paths by a magnetic field. They were much lighter than hydrogen ato

Comets Word Count: 2365 The first written records of comets date back to nearly 3,000 years ago from China and Europe. The accounts of these comets were believed to be the causes of terrible events that occurred afterwards. In more recent times, however, astronomers have found out what they really are. A comet is basically a mixture of ices, from both water and frozen gases, and dust. They have also been given the names “dirty snowballs” or “icy mud balls.” The typical comet is less than 10 kil
