erive an expression for the instantaneous power absorbed by the resistor as a function of time. (b) Integrate the resistor power as a function of time from t = 0 to t = ∞, and show the total energy absorbed by the resistor does not depend on its resistance. At all. This very weird result is the cause of much power loss in memory circuits and much debate on online physics forums.

Consider a large supermarket chain (for example, Kroger, the parent corporation of Fry's Food and Drug) as opposed to a typical department store, such as Macy's. Which firm would you expect to have the highest net profit margin? Which firm would you expect to have the highest inventory turnover and/or asset turnover? Explain the reasoning behind your answers. Considering these factors, can you develop a general relationship between profit margins and turnover? Explain.

An Olympic sized swimming pool that measures 50 m by length and 25 m by width is swept by wind at a speed of 3 m/s along its length. While the pool is wet decked (namely the water surface is levelled with the decking), there is a perimeter drain around the pool. The pool water is maintained at 27 C,while the surrounding air temperature is 5 C and 20% relative humidity, and the sky temperature is -12 C. As it is nighttime, there is no solar insolation. The emissivity of the pool water can be taken to be O.8. The latent heat of evaporation of water can be taken to be 2463 kJ/kg. DAs of water-vapour air mixture is 2.437x10-5 m2/s.

According to a survey, approximately 58% of US adults believe that they have achieved, or are within reach of, the "American Dream" (that is, home ownership and financial stability). Assume that the true proportion of all US adults who have reached or are optimistic about reaching the American Dream is p=0.58. Now consider a random sample of 400 US adults. Complete parts a and b below. What is the probability that between 49% and 60% of the sampled adults believe they have reached or are optimistic about reaching the American Dream?

The function below draws a circle of radius r and centered in x0,y0 and returns its length. Complete it: `circlef (r,x0,y0) | I phi=linspace (0,2*pi, 100); x=r*cos(phi) +x0; y=r*sin (phi)+y0; plot(x,y); axis('equal'); length=2*pi*r; end i.Create it and save it as an M-file in your MATLAB folder with the name circlef.m ii. Call it from the command window and try it with r=9, xo=0, yo=o. Circle length: iii.hold on the plot and call the function again with r=2, x0=4, yo=4, and then with r=2, xo=-4, yo=4, and finally with r=1, xo=0, yo=0. Sketch the resulting plot:
