There was a huge evolution as to understanding what an atom was and there were many scientists who helped to make this happen. The first scientist was Democritus‚ he lived from 460 BC to 370 BC. His main theories were that everything is made up of atoms‚ atoms cannot be divided‚ and atoms are small and solid particles. He named the atom “atomos” it was greek word and it means “not able to be divided.” The next scientist who worked with atoms was John Dalton‚ he lived from 1766 to 1844. His main theories

Lab V‚ Problem 8: Magnetic Force on a Moving Charge John Greavu Partners: Hannah Eshenaur and David Sturg August 15‚ 2013 Physics 1302W‚ Professor: John Capriotti‚ TA: Barun Dhar Objective In order to improve the design of an electron microscope‚ we attempted to use a magnetic field to control the electron beam. Utilizing a cathode cay tube (CRT)‚ we oriented a magnetic field perpendicular to the axis of the CRT’s electron beam. From previous experience‚ we decided on using Helmholtz coils to

Today‚ I’m going to be talking about the Legislative Branch‚ and how it’s divided in three different parts. The three different parts are “Legislative Branch”‚ “Powers of congress”‚ and “Government oversight”. The Legislative Process is the steps that congress takes to approve a law. The first step that congress has to take was to introduce the introduction of the bill to congress. After introducing it to congress‚ the bill will have to be reviewed by the appropriate committee. Then after

There are three major chemical bonds and they are‚ Ionic‚ Covalent‚ and Hydrogen bonds. An example of a covalent bond would be SCl^2 which is Sulfur dichloride. SCl^2 is a covalent bond because since they are close to each other in valence electrons‚ they have almost full outer shells so they share electrons with one another. A good example is table salt NaCl‚ because they are on opposite sides of the periodic table therefore that means that they are different and one has less valence electrons than the

Max Weber said there are three components to social class power‚ prestige and property; also known as the three P’s of social class. Property (or wealth) can be seen as not only owning property‚ but controlling the property for their benefit. Power is the ability to control other people even if they resist the control. Lastly‚ prestige is the admiration of people to someone who has wealth and power (Henslin‚ 2014). The conflict perspective emphasizes that the creation of social classes with the

If cholesterol.com will prove to be more efficient and Windham will switch away from MedNet‚ the decision of future MedNet strategy will depend heavily on the competitive landscape and internal flexibility of the MedNet.
