Suppose we use a light sensor to measure the change in intensity of reflected light from a light bulb as we move away from an extended object such as a piece of paper and then at a small circle of white paper on a black background. a. Will the changes in intensity be different for the two objects? b. Where does the light reaching the sensor originate? Describe the complete path it takes from the source to the sensor. c....
Experiment 2: Inverse Square Law The inverse square law is a concept that comes up in several areas of physics. This experiment does not demonstrate how gravity "works,” but it aims to give you a better picture of how the force of gravity diminishes greatly as distance increases. In Figure 6, gravity is represented by the amount of light spread out over an area, A. Figure 6: Inverse square law. "A" represents the original area at distance, d. Note the...
2. Download the annual real GDP and GDP data of the United States 1950-2018 from FRED. For the real GDP, the data online is chain-weighted and uses 2012 as the base year. In the lecture hursday, I showed you the detailed method and calculated the new chain-weighted real GDP when 1990 is the base year. You are required to calculate a new sequence of chain- weighted real GDP given a new base-year. The base year you should use in your...
