Final answer:
The correct energy transformation sequence in a waterwheel-powered electric generator system is mechanical to mechanical, then to electrical, and ultimately to radiant energy. The process involves converting the mechanical energy from flowing water into electricity, which can then be used to generate light or other forms of radiant energy.
Step-by-step explanation:
The correct option that describes the energy transformations in a waterwheel-powered electric generator system is (B) Mechanical, mechanical, electrical, radiant.
In this system, the gravitational potential energy of stored water is converted into kinetic energy as the water flows and turns the waterwheel. The mechanical energy of the moving water is then transferred to the waterwheel, creating rotational mechanical energy. This mechanical energy turns a shaft within the electric generator. As the shaft rotates, it transforms mechanical energy into electrical energy through the interaction of magnets and coils in the generator. Finally, electrical energy can be used to produce radiant energy in the form of light or other types of electromagnetic radiation.
