Coulomb

The invisible being that created the push or pull of an object has been a law of science since the early ages. The first scientists to study this entity was Ancient Greek scientists Archimedes. His theory is now referred to as Archimedes 's principle, or the law of fluid mechanics. It implies that there is force that is exerted on a body immersed in a fluid, whether fully or partially submerged, is equal to the weight of the fluid that the body displaces. He hypothesized this theory while in…

In radiation therapy, bolus is a modality that helps compensate for differences in body contours, stop skin sparring, and to raise dose buildup on the patient’s skin (Washington, p. 171). Bolus is a tissue equivalent material, but there is not just one type of bolus. Superflab is a commercial bolus that most clinical sites use, but other bolus variations are also available for use. There is no study that compares Superflab, neon green Play-Doh, orange Play-Doh, and uncooked rice for providing…

Magnets are one of the fundamental items in physics. This paper is meant to provide a general overview of magnets and their uses, as well as an in depth look into certain aspects of magnetism and how they relate to everyday life. Most images of a magnet come to mind as a tiny object used for hanging things on a refrigerator. But other applications are much more useful in our society in general. They are used in all kinds of speakers, in many computer parts including hard drives (for recording…

Early Atomic Experiments Joseph John Thomson conducted an experiment that is known today as the CRT Experiment. The outcome of this experiment was JJ’s discovery of the electron. CRT is an acronym for Cathode Ray Tube, this gives a broad concept of what the experiment is about. The basic components of the experiment include, a glass cylindrical tube with most of the air inside vacuumed out of it, and inside the tube is Electrode for each side. One of the Electrodes is negative and entitled the…
