Question

What is the wasted energy when an airplane flies?
 

  1. Electrical
  2. Heat
  3. Sound
  4. 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.
