Apakah perubahan tenaga yang betul?Water stored behind a dam flows down and turns a turbine. The turbine turns a generator to make electricity. What is the correct energy change?
Show answerHide answer
B
Water held high up has potential energy. When it flows down it has kinetic energy, which turns the turbine and generator to give electrical energy. The water has no chemical energy, so the last option is wrong.
