II- Research how engineers dispose of the waste produced by the generation of nuclear energy. Be specific and provide details. Please cite sources for all research completed while answering this question. Explain in detail regulations and environmental concerns that may apply (include a minimum of three – more is better). Be specific and provide details. Please cite all your sources. Which field(s) of engineering is involved with these disposal Projects? Are these fields of engineering of interest to you? Why or why not. Explain in detail    Answer all 3

Sustainable energy folks are investigating the possibility of creating super sized banks of capacitors that store electrical energy during low demand times so that it can be used during peak demand times. Suppose such a capacitor was designed to deliver 3.50 Megawatts for a period of 8.00 hours. (1 Megawatt is 1 million Watts). By how much would this capacitor bank's mass decrease as it is discharged? ________ kg

9. The amount of current that will operate an overcurrent protective device is inversely proportional toA. resistance.B. voltage.C. time.D. capacitance.

Predictive maintenance is to be applied to an industrial conveying system.a) Discuss and illustrate the difference between reactive, preventative, and predictive maintenance.b)  Describe several of the techniques that could be used to develop a predictive maintenance system for the conveyor system. Consider some  of the  sensing techniques  that might be used and what parameters might be measured to detect component degradation.c)  If the predictive maintenance system described in b) detects that the conveyor system is vibrating abnormally, discuss what condition this could indicate and what maintenance might be required.

State the condition for the stability of a linear system.

Discuss typical structure of the modern electrical grid. Include all elements and provide short description of their role in the system

With the aid of well labeled diagrams, explain the principle of operation of: a. a pyranometer. b. a wind turbine, from resource to electrical power

Which of the following is true regarding conductors? O The potential anywhere inside a conductor is always equal to the potential anywhere at the surface of the conductor. O The potential anywhere inside a conductor is always greater than the potential anywhere at the surface of the conductor. O The potential anywhere inside a conductor is always less than the potential anywhere at the surface of the conductor. O The other choices are too vague. More information is needed.
