Water flowing over a waterwheel is an example of kinetic energy transforming in to what type of energy? A) Thermal energy, B) Electrical...

Waterwheel is a device which harvests the the energy of water. Here, the kinetic energy of water is converted to mechanical energy. Historically, waterwheels were used to power watermills for grinding grains, such as rice and wheat. Another application was in crushing ores, which helped in saving manual labor and increased ore processing capacity. Timber saws were also operated by using the kinetic energy of water flowing over waterwheels. In modern times, the same concept is used for generation of electrical energy in hydroelectric projects. Here, the energy of falling water is used to rotate the blades of turbines, thus converting the water energy into mechanical energy. These turbines then convert this mechanical energy to the electrical energy. Hence, option D is correct.

Hope this helps.
