Answer:
Sound
Step-by-step explanation:
Hi there,
To best answer this question, look at the pattern of how different energy forms are related. Notice, the energy associated with Light also creates Heat, and the energy creating Heat created Light.
Similarly, kinetic energy (the energy of motion and movement) typically creates sound as well, which are vibrations of air in longitudinal waves. Notice, the Blender and Fan create Energy of Motion, and thus create Sound.
Apply this to Washing Machine, the Energy of Motion also creates Sound. This makes sense, as Washing Machines use motors for kinetic energy to rotate clothes, which does not make heat, light, or additional motion. Just sound!
Thanks,
