1) A newly retired individual purchased a large plot of land in the Amazon jungle at an extremely low cost, with plan of making a small house and staying there. The major problem is that the nearest source of electricity is 1500 miles away. He decides to build a small hydroelectric generator under a 75-m high waterfall located nearby. The flow rate of the waterfall is 10 m/h and he estimates that the house needs 750 kWh of electricity per week. Calculate the maximum power that is theoretically available from the waterfall and see if it is sufficient to provide electricity to the house. (7 marks)
