- The speed of light is 2.998*10^8 m/s. How far does light travel in 6.0 μs? Set the math up. But don't do any of it. Just leave your answer as a math expression. be sure your answer includes all the correct unit symbols.arrow_forwardWhich of the following is a CORRECT description of Einstein’s Geometric Theory of Relativity? A. This theory supported Isaac Newton’s description of gravity as a spontaneous force of attraction between two objects with mass. B. This theory implies that the gravitational force of attraction between two objects with mass does not come from gravity itself. C. This theory describes that space and time are eleven-dimensional where each dimension has distinct characteristics and features. D. This theory has two postulates similar to the Special Theory of Relativity that the laws of physics and speed of light are invariant.arrow_forwardWhich of the following is a CORRECT description of a consequence of the General Theory of Relativity? A. Black holes are regions of spacetime where light is emitted in the form of dark energy. B. Gravitational lensing enables us to see the beginning of the universe through redshifts. C. The elliptical path of Mercury is precessing about a certain degree in each century. D. Light is greatly bent by lighter objects than heavier objects due to its small circumference.arrow_forward
- Which of the following is one of the postulates of Special Relativity? Time dilates and length contracts as an object approaches relativistic speeds. . Events that are simultaneous in one frame may not be simultaneous in another. . All laws of physics are of the same form in all inertial frames of reference. The speed of light in vacuum is constant and dependent on the speed of the source.arrow_forward1. Two atomic clocks are synchronized. One is placed on a satellite, which orbits around the earth at high speed for a whole year. The other is placed in a lab and remains at rest, with respect to the earth. You may assume that both clocks can measure time accurately to many significant digits. a. Will the two clocks still be synchronized after one year? Explain your reasoning. b. Imagine that the speed of light was much slower than its actual value. How would the results of this experiment change if the speed of light was only twice the average speed of the satellite? Explain your reasoning, using a calculation.arrow_forwardThe Big Bang Theory is currently the most widely-accepted explanation for the origin of the Universe. As technology has emerged, new data has been collected to allow for a clearer understanding of how the Universe is changing and the possible things that might happen to it in the future. Which of the following is not a question that can be answered using scientific processes? o What was the cause of the Big Bang? o What is the type of energy emitted by celestial objects? o What is the rate at which the universe appears to be expanding? o What are the chemical elements that exist in the other parts of the galaxy?arrow_forward
