Truss Bridge Physics 141 Robin Hoffmeister There is many reason that we need bridges in every day of our life‚ from sufficient means to pass over a roadway‚ waterway‚ railway‚ or other structure. You don’t even think about them because it takes no effort to get over them and they are just there for your use. So if you don’t think of them for everyday use I highly doubt that you would think of the physics that is involved in putting one together or the kind of force the bridge can actually

The purpose of this paper is to elaborate on the Tuskegee Experiment based upon previous international study‚ it will also state the original study and where did it originate‚ the purpose of the study and the results. It will also state who or what were the principal investigators‚ the participants (gender‚ race‚ age)‚ why and how did this study end. The original study of the Tuskegee research was a disreputable medical experiment carried out in the United States between 1932 and 1972‚ in

Plasma Complexity! Plasma is said to a substance similar to gas in which a certain portion of the particles are ionized. The basic premise is that heating a gas dissociates its molecular bonds‚ rendering it into its constituent atoms. Further heating leads ionization‚ turning it into plasma: containing charged particles‚ positive ions and negative electrons. The presence of a non-negligible number of charge carriers makes the plasma electrically conductive so that it responds strongly to electromagnetic
