An object with mass m on a horizontal frictionless surface is attached to one end of a horizontal spring with the other end of the spring being attached to a rigid wall. Force is momentarily applied and the mass is set in motion moving in horizontal simple harmonic motion. If the spring constant of the spring is 45N/m and the spring is stretched -.88m when the object is accelerating at 1.4m/s^2. What is the mass of the object ?

Faraday's Law - Induced Currents and Induced Electric Fields - Prelab Question: How can a magnetic field produce a current? Part P-1: The Galvanometer Previously, you have used the built in functions of digital multimeters to serve as a voltmeter or ammeter. In those cases you learned how to avoid damaging the equipment before you started the lab. Therefore, before starting this lab let's investigate how a galvanometer works. A galvanometer is shown in the picture to the right. The galvanometer is designed to measure miniscule values of current and because of that many galvanometers do not have units on their face. Name: Date: Lab day & time: 1. Why would it be advantageous, to measure miniscule measure levels of current in this lab. Explain your answer with your knowledge of physics and justify your answer based on what you will be asked to do in this lab. 2. What kind of measurement issues could you have when using a galvanometer? Consider how fast small levels of current might change. Make sure you explain your answer. 3. How could you damage your galvanometer and how could you avoid this? Explain your answer. Last Revised 05/26/2015 Faraday's Law -11.1

3. A market researcher wishes to estimate the demand for a gaming console made by company M. M competes with two other companies S and N. The researcher believes that the log of demand for the gaming console, In M, depends on the log of the price of M, In PM, and the log of the price of each of the substitutes, In Ps and In Py along with the log of the income level, In inc, the percentage of males aged 15-32 (PCTMALE), and the number of game titles available, TITLE. (a) Write out a population regression function that specifies this relation. (2 marks) (b) Suppose that your model from (a) is estimated (the regression is run). Now you wish to jointly test if cross-price elasticities of demand are the same and both price-elasticity and income-elasticity of demand are equal to 1 (unity). Write out the null hypothesis that you are testing and write out the new regression that can be estimated to carry out this test. (5 marks) (c) Explain whether it will be possible to use the R-squared form of the F-test to test the set of restrictions from (b). (3 marks)
