Force Fields Summary Response In Michio Kaku’s article “Force Fields”, he explains how a force field can deflect laser beams. Throughout out his article Kaku shows that future science might be able to provide the same technology as science fiction TV shows such as Star Trek because he believes that science would overcome issues of limited technology. In order for force field function correctly he suggests that there has to have three layers. The outer layer is high temperature plasma created by supercharged plasma window. The middle layer is a group of laser beams.
These protons and neutrons of the nucleus are called nucleons. The force that holds these nucleons together inside the nucleus is called the strong nuclear force. This force has special properties as it is independent of charge and is stronger than the electrostatic repulsion forces between protons. This understanding of stability has allowed scientists to
The coil is the part of the machine that will actually make it work, by giving of a radio frequency. The scanner uses hydrogen atoms to tell the difference between different tissues. MRI scanners will use ‘spin’ which is a property in the machine which can tell the differences between tissues, such as fat, tendons, and muscle. Once the MRI scanner is turned on and the patient is in ready to be scanned the nuclei of the hydrogen atoms in the machine can spin in one of two different directions. The hydrogen atom nuclei can change the direction of spin to the opposite direction.
The magnetic field permeates the tissue and causes the nucleus scale magnets in the tissues to rotate. By observing what frequencies are absorbed by the atoms the doctors can determine what sorts of atoms are present at a particular place in the body. 2. Explain how a sound is actually a form of energy? In what medium do sound waves travel?
Wilhelm Roentgen & His X-Rays Wilhelm Roentgen, a German physicist, was the first accredited with the discovery of X-rays. Although he was not the first to bear witness to their effects, he was the first to intentionally and systematically study them. Ivan Pulyui, William Crookes, Johann Wilhelm Hittorf, and Eugen Goldstein were some of the first few to begin research on X-rays along with Roentgen. He wrote an initial report "On a new kind of ray: A Preliminary Communication" and on December 28, 1895 submitted it to the Wurzburg’s Physical-Medical Society journal. This was the first written report of any kind on X-rays.
Staining methods allow researchers to study the structure of a neuron. Being able to study different aspects of neurons helps researchers better understand their functions. The Golgi stain and the Nissl stain are two of the most used and successful stains used today each highlighting different aspects of the neuron. The Golgi stain was discovered accidentally by Camillo Golgi in the 1870s when he combined potassium chromate and silver nitrate and stained a piece of neural tissue using this solution. The potassium chromate and silver nitrate reacted together and created silver chromate, which ended up invading a select number of neurons and staining them black.
If the quantum dots are placed in the cavity, the spot on the wafers where there are no crystals, in the middle, and capture electrons then the aims of the process are a success. (Hennessey Interview) Kevin explains that you want to then put the process material into devices. This control of powerful light in this small cavity is what causes much speculation. The new devices which use this method are called quantum effect devices. According to Kevin, lasers and lights could be replaced with this technology.
Using the Flame Test to Prove Different Colors of Light are Emitted as the Electrons Move from an Exited State Back to a Ground State 1. Introduction / Purpose (5 points) According to Mr. Darrell Ebbing and Mr. Steven Gammon (2013, p. 273) Albert Einstein “reasoned that if a vibrating atom changed energy, from 3hv to 2hv, it would decrease in energy by hv and this energy would be emitted as a quantum of light energy.” The reasoning was based on “Mr. Max Planck’s work on Quantization of Energy (Ebbing & Gammon, 2013, p. 273)”. In this experiment, this reasoning will be tested by taking small amounts of four different salts that contain metal, Sodium Chloride (NaCl), Potassium Chloride (KCl), Lithium Chloride (LiCl), and Barium Chloride (BaCl_2), and heating them using the flame of a Bunsen burner. As Model Science (2011) explains, the experiment will show that as the salt with the metal is “burned, the electrons will be excited (i.e., move to another energy level) and as these electrons fall back from one energy level to another, they will emit photons of light.
Wan Huang Oct 26, 2012 Flame Tests Lab Introduction By placing atoms of a metal into a flame, electrons can be induced to absorb energy and jump to an excited energy state, a quantum jump. They then return to their ground state by emitting a photon of light (the law of conservation of energy indicates that the photon emitted will contain the same amount of energy as that absorbed in the quantum jump). The amount of energy in the photon determines its color; red for the lowest energy visible light, increasing energy through the rainbow of orange yellow green blue indigo, and finally violet for the highest energy visible light. Photons outside the visible spectrum may also be emitted, but we cannot see them. Hypothesis If we can identify the color of flame after burning the atoms of metal, then we can determine the amount of energy in the photon.
Bonding Fill in the missing words, the first letter of the blank words are an anagram of a key bonding word. What is the mystery word??? Why do Chemical bonds form? Bonds between atoms involve their outer electrons. When atoms bond together they share or transfer electrons to achieve a more stable electron arrangement, often a full outer main level of electrons, like the noble gases.
