Astronomy 10 Chapter 11 1. Both used to be normal stars but the white dwarf ran out of hydrogen, they are both subjected to gravitational theories. A Neutron star is a fluid of neutrons, as hot at its surface as the inside of the sun and has a greater magnetic field. 3. Because its density is so high, neutrons spin in the same way that electrons do so must obey the Pauli Exclusion Principle.
The process of changing one element into another is called transmutation. The two main ways that a transuranic nucleus can be produced is by bombarding its nucleus with ions or neutrons. These ions or neutrons can be captured by the target nucleus and produce heavier nucleus. Transuranic element 1: U-238 is bombarded with neutrons it can be converted to U-239 which then undergoes beta decay to produce neptunium and plutonium. Pu-239 is changed to americium-241 by neutron
Electromagnetic Radiation: Radiation consisting of oscillating electric and magnetic fields, namely gamma rays, X-rays, visible light, ultraviolet and infrared radiation and radio waves. Interstellar Medium: Interstellar gas and dust. Julian date: A Julian date or day number is the number of elapsed days since the beginning of a cycle of 7,980 years invented by Joseph Scaliger in 1583. Magnetic Field: A region of space near a magnetized body within which magnetic forces can be detected. Neutron Star: A very compact, dense stellar remnant composed almost entirely of neutrons.
They go in order of the rainbow; red being the weakest and violet being the strongest. PURPOSE: The purpose of this experiment is to burn atoms of a metal using a flame burner to see how much energy a photon releases by the color of light emitted. Also by observing the photon; the ability to specify an unknown substance will be available. PROCUDURE: Seven well plates were obtained and labeled with the name of the known substances. In each well plate place a small amount of known substances into the well plate.
6. What is CMB radiation? Radiation emitted by the Big Bang, which now has caused a much bigger wavelength because of the expansion of the universe. 7. Which theory is supported by the following evidence- h) red shift-both i) the cosmic microwave background radiation-Big Bang.
The most logical answer is A. When the earth was just starting to form a big astoride hit earth and a large amount of material flew off to form the moon. 3. Sunlight is created from_______ a. Sun light Bulbs b. Thomas Edison c. Yo Moma d. Energy from Nuclear Fusion i. D. Sunlight is the energy that is released when a nuclear reaction causes hydrogen to form in to helium 4.
1. Explain how medical magnetic resonance imaging (MRI) exploits the magnetic properties of the nucleus. MRI’s rotate the nucleus of an atom, producing a magnetic field. During a MRI, a person is placed between the poles of a strong magnet. The magnetic field permeates the tissue and causes the nucleus scale magnets in the tissues to rotate.
The atomic bomb works by a physical phenomenon known as Fission. In this case, particles, specifically nuclei, are split and great amounts of energy are released. This energy is expelled explosively and violently in the atomic bomb. The massive power behind the reaction in an atomic bomb arises from the forces that hold the atom together called the strong nuclear force. The element used in atomic bombs is Uranium-235.
On each of these wafers the quantum dots are in between the substrate. On the last page it is shown, where the Indium quantum dots lie. In Kevin's assessment each quantum dot can "hold electrons. This control of the electrons causes them to emit light. 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.
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.
