An appliance store wants to conduct an experiment to determine the effect of advertising on sales revenue.  The data table contains the advertising expenditure (in $100s) and sales revenue (in $100s) in the past 5 months.  Below the data table, you will see the results of the regression analysis that was performed using Excel.  You need to decide what the sales revenue will be with an advertising expenditure of $150, if possible.  Discuss why you are able to use the regression equation to predict the sales revenue.  What will be the sales revenue rounded to the nearest dollar?  Support your answer.        Advertising expenditure ($100s) Sales Revenue ($100s) 1 1 2 1 3 2 4 2 5 4     Coefficients Standard Error t Stat P-value Intercept -0.1 0.635085296 -0.157459164 0.88488398 X Variable 1 0.7 0.191485422 3.655630775 0.035352847

Calculate the time required to discharge a capacitor in a RC circuit when only one electron’s charge is left; that is when q = e. In the circuit we have R = 670 kΩ{“version”:”1.1″,”math”:”Ω”}, C = 0.920 μ{“version”:”1.1″,”math”:”μ”}F, Q0 = 7.00 μ{“version”:”1.1″,”math”:”μ”}C.

The wires in a household lamp cord are typically 3.0 mm apart center to center and carry equal currents in opposite directions. If the cord carries current to a 100-W light bulb connected across a 120-V potential difference, what force per meter does each wire of the cord exert on the other? Is the force attractive or repulsive?
