Pickett's Charge

objects, when determining their charge and how they interact, all seen by a firsthand course of action. This process extends to determining the charge of objects with respect to this principle by the utilization of tape. II. Hypothesis: If one were to force a certain charge onto a piece of tape then they would be able to evaluate magnitude and orientation of the charge of not only the tape, but any object that they would so desire. Such as testing, the polarization of charge on…

"Energy Story", "Hands-On Science with Squishy Circuits" and "Conducting Solutions". All very informative sources about electricity and how its conducted. In Energy Story what the author is explaining the basics of the science behind the amazing process that allows us to have electronic instruments that run on this source of energy. The purpose of the article "Energy Story", is to inform the reader about the scientific force behind this process, and what goes on when we flip a light switch. It…

Elements above the atomic number 95 are produced in a particle accelerator by accelerating a small charged nuclei (such as Helium, Boron or Carbon) in a particle accelerator to combine with a heavy nucleus (often of a previously made transuranic element) target. The transuranic elements have short half-lives as the atomic number increases. The smaller nuclei combines within the target nucleus, creating a new unstable nuclide or radioactive isotope. The high speeds are required to overcome the…

Today we might know an atom being the smallest piece of an element that represent an element, but you might not know the whole story. It all being in 1803, when a curious guy, known as John Dalton, who proposed an “atomic theory” with spherical solid atoms based upon measurable properties of mass. Later on Dalton introduced his belief that atoms of different elements could be universally distinguished based on their varying atomic weights. John Dalton's research not only changed the face of…

Since electrical appliances became a very important in people’s life, scientists have studied the effects of magnetic fields on human health. In a study of magnetic fields and cancer, “Animal and Cellular Evidence,”[1]. Bo Holmberg compares many studies that apply magnetic fields on mice and rats and he reports the effect of magnetic fields on skin, liver, harmonies, and DNA. He said that studies on animals were effective in proving the extent of exposure from magnetic fields enough to cause…

Electrosurgery is the passage of high frequency electrical current through the body to achieve a desired surgical effect. The surgical effect can be achieved by, cutting, coagulating or fulgurating. The techniques of electrosurgery use today were developed in the early part of the 20th century; however, the history of the technique goes back as far as the early 19th Century. The French Physicist Becquerel was the first to demonstrate electrocautery, using electricity to heat a wire needle. Later…

current pulsing through the wire. Electric current is nothing but the rate of flow of electric charge through a conductor with respect to time. It is caused by drift of free electrons through a conductor to a particular direction (Electric current). The particles that carry charge through wires in a circuit are mobile electrons. The electric field’s direction in a circuit is the direction that positive charges are moving. Thus, these negatively charged electrons move in the direction opposite…

Key Idea I The arrangement of electrons is distributed between four orbital’s; S, P, D and F. Each orbital is a different shape and holds a different number of electrons. Orbital S is a circle and it contains two electrons and orbital P has three different shells. One shell is an infinity sign, the next is a crooked infinity sign and the last is shaped like an upright infinity sign. Each shell can hold two electrons which allow orbital P to hold six electrons, orbital D can hold ten electrons,…

Protein X has a pI of 5.9, Protein Y has a pI of 7.6, and Protein Z has a pI of 8.5. For each of the methods below, describe how you would go about purfying Protein Y from Proteins X and Z (provide a pH that you would use and why.) Anion exchange chromatography: In anion exchange chromatography negatively charged ions will bind to the column. This will leave positively charged ions flushed through the column. By picking a pH of 6.5, protein X will flush through the column while protein Y and Z…

Solutions", the central idea or purpose is to teach about solutions and how some can conduct electricity better than others. The passage also talks about ions. According to the article ions are atoms or small groups of atoms that have an electrical charge. If a solution has more ions than the solution can conduct electricity better than a solution that contains less ions. Pure water contains few ions, but if it is mixed with salt or other high ion…
