A 50-Hz 10-MVA, 66/22-kV distribution transformer has a full-load efficiency of 98% at 0.8 lagging power factor. The transformer core loss is 80 kW. The transformer supplies an industrial load that has a constant demand of 5000 kW at 0.65 lagging power factor. The cost of energy is $0.1 per kWh. 1. In the following questions, assume that the voltage at the load terminal is maintained constant at 22 kV. calculations....

I don't know how much help you can give me but if you can please help answer 5-8! TIA Shake the non-fixed end of the slinky to create a standing wave. If you do this on the floor, it would be best to have a hard surface, so the slinky is not sliding against carpet. Practice until you are able to produce standing waves with two nodes(at the two ends), three nodes (two at the ends and one in the middle), and...
