5. A hydroelectric generating station uses falling water to turn turbines which are
connected to generators that create electricity. The electricity is then sent out
on wires to your home where it is used in appliances, etc. Using the physics
you have learned in this course, elaborate on this process by making valid,
relevant, quality points (use point form) in the space below. You should use
physics vocabulary and theory and limit your discussion to the situation
described. For full marks, make 9 valid, relevant points. [9 marks]
