Which of the following is an example of a renewable natural resource? A. crude oil B. coal C. wave energy D. copper

c. wave energy

Explanation:

wave power is the capture of energy of wind waves to do useful work

before, trains worked using the steam engine. thus, it uses heat so it is crucial to apply heat balance. the steam engine absorbs energy during the stage of boiling water. so, this is the endothermic reaction. when the steam is used to work the piston, it has to release this energy through running the train. the excess energy is released as an exhaust to the chimney. this is the exothermic process because it releases energy to the surroundings.
