November 8, 1895 Wilhelm Conrad Roentgen - CORRECT ANSWER-X-rays: discovery date and discovered by voltage - CORRECT ANSWER-kVp measures: current - CORRECT ANSWER-mA measures: Gustav Bucky and H. Potter 1921 - CORRECT ANSWER-Inventor of moving grid and year introduced: international system (Le Systeme International d'Unites) - CORRECT ANSWER-modern metric system in science, SI units, stands for: matter - CORRECT ANSWER-anything that occupies space and has mass atoms and molecules - CORRECT ANSWER-fundamental building blocks of matter E = mc² - CORRECT ANSWER-mass-energy equivalence formulated by Albert Einstein that demonstrates matter and energy are the same thing electromagnetic energy speed of light - CORRECT ANSWER-type of energy in x-rays, gamma rays, visible light...: speed of travel: 3 x 10⁸ m/s - CORRECT ANSWER-speed of light: radiation - CORRECT ANSWER-energy emitted and transferred through space true - CORRECT ANSWER-true or false: radiation is ionizing and non-ionizing ionization - CORRECT ANSWER-this occurs when an electromagnetic wave, or subatomic particle, has enough energy to remove an orbital electron from an atom x-rays, gamma rays, ultraviolet light - CORRECT ANSWER-forms of electromagnetic radiation with enough energy to ionize alpha and beta particles - CORRECT ANSWER-particle type of radiation with enough energy to ionize base quantities - CORRECT ANSWER-building blocs of all other quantities (mass, length, time) mass kilograms (kg) - CORRECT ANSWER-quantity of matter contained in any physical object: unit of measurement: true - CORRECT ANSWER-true or false: mass remains unchanged regardless of state derived quantities - CORRECT ANSWER-a combination of one or more base quantities (volume, velocity, acceleration, force..)
