Answer:
Chemical energy to electrical energy to mechanical and thermal energy
Explanation:
In the rotating fan, the chemical energy stored in the battery is used to generate electrical energy.
The electrolytes within the battery undergoes chemical reactions that produces electric current.
- The current is being used to drive the motor of the fan to produce a mechanical energy as it rotates.
- In like manner, heat energy is also produced.
- So, energy is simply being transformed from one form to the other in this system.
Wavelength = speed / frequency = 340 / 17000 = 0.02 m
