The net discounted return expected from an investment in the rental homes tract-after deducting the cost of the investment-is Based on the results of your analysis, which of the following statements best reflects your decision regarding the commercial or residential lease opportunities? As the rental homes tract has a NPV that is greater than that expected from the office building, it is more financially sound to invest in the residential lease property. Because the office building is expected to generate a negative NPV, you should not consider making this investment. Based on the numbers alone, you should prefer an investment in the office building since it has a net present value that is greater than that expected from the residential lease property (rental homes tract). Given that the rental homes tract has a NPV that is greater than that expected to be generated by the office building, you should prefer to invest in the residential lease property. As the office building has a NPV that is greater than that expected from the rental homes tract, it is more financially sound to invest in the commercial lease property. Because the rental homes tract is expected to generate a negative NPV, you should not consider making this investment.

Q5 A three-phase inverter is used to achieve variable-speed control of an induction motor having the following parameters: Rated Voltage: 415V (line-to-line, rms) Rated Frequency: 50Hz Number of Poles: 2 $X_s = 0.70\Omega$ $R_s = 0.09\Omega$ $X_r = 0.90\Omega$ $R_r = 0.15\Omega$ $L_m$ is assumed to be large (a) Sketch the output voltage waveforms produced by fundamental frequency (square wave) modulation of the three-phase inverter. Discuss the problems that would be encountered if this voltage was used to drive a three-phase induction motor. 20% (b) Explain how the inverter can be used to achieve variable speed control of an induction motor and show how the inverter generates a balanced three-phase ac output voltage with controllable amplitude and frequency. 30% (c) If the motor is under constant $V/f$ control operating at a slip of 0.08 and the inverter output frequency is 30Hz, calculate the motor torque and rotor current. 30% (d) The motor operates at steady-state under the conditions specified in (c). If the inverter output frequency is suddenly increased to 40Hz while still under constant $V/f$ control, what is the torque produced at the instant of the sudden frequency increase? 20%

Write a program that asks the user to input the lap times for laps they've run around a track and stop inputting with -1. All lap times should be positive. Display the slowest, fastest, and average time for the user. Please input the lap time for lap 1 (-1 to stop) >> 21 Please input the lap time for lap 2 (-1 to stop) >> 24 Please input the lap time for lap 3 (-1 to stop) >> 18 Please input the lap time for lap 4 (-1 to stop) >> 16 Please input the lap time for lap 5 (-1 to stop) >> 27 Please input the lap time for lap 6 (-1 to stop) >> -1 The time of your fastest lap is: 16 The time of your slowest lap is: 27 The average time of your laps is: 21.2
