Answer 1

Answer:

a)- When water made to fall from a certain height on a turbine blade ( different turbines are used as per size, height or to get better efficiency). Blade rotates rotor then it rotates electric generator which produces magnetic field in the generator then electricity produced.

b)- 1 MW =one million watt = Ten Lacks Watt 1000 K watt =1 K Watt = 1000 Watt It represent 1000 Jules of power consumption in one second.

c)- Mass population relocation and Ecology disaster. Also it's a huge dam in a earthquake prone area which can lead to breakage of dam if a high rector scale earthquake happens. This will lead to mass destruction with no remedy.

d)- Pressure energy and Potential Energy convert into Mechanical Energy. Which rotate turbine blade. Subsequently electric generator rotor.
