Spinning wind turbine blades have kinetic energy. wind turbines transform this energy into electric energy and heat energy in a closed sytem. which of the following statements about this energy transformation is true? a. all of the heat energy is transformed into electric energy. b. half of the kinetic energy is transformed into electric energy and heat energy. c. all of the kinetic energy is transformed into electric energy and heat energy. d. half of the heat energy is transformed into electric energy.

All of the kinetic energy is transformed into electric energy and heat energy

Explanation:

According to law of conservation of energy the amount of energy can transfer from one form to another form. As this system is closed system so the amount of energy transform is not fixed. But all of the kinetic energy is transformed into electric energy and heat energy.

So, option C is correct.

the moving of the box is a result of centripetal force. think of that  as a car or a truck in this case creates a turn, the force of friction performing upon the turned wheels of the car runs centripetal force obligatory for circular motion for the things inside it.
