$0.05 / 3.6e6J (7.2e15 Joules) = $100 million. Calculate the energy in joules made available when 1 kg of water falls 30 meters if 90% of the energy can be converted to a useful form. Calculate the energy in joules made available when 1 kg of water is cooled by 2°C if 3% of this energy can be converted to a … ................
