Question
What is the wasted energy when an airplane flies?
- Electrical
- Heat
- Sound
- motion
Hint:
Sound and heat
The correct answer is: Sound
- As the speed of the airplane increases, the chemical energy is converted into kinetic energy.
- As the airplane goes higher, the mechanical energy is changed into gravitational potential energy.
- While flying, some energy is lost through drag to thermal (heat) energy and sound energy.
