A blender takes in 180 J of electrical energy. Of the 180 J, 90 J are transformed into kinetic energy, 60 J are transformed into thermal energy, and the rest is transformed into sound.

What is the sound energy generated by the blender?

Total energy = 180 J. Used: 90 J (kinetic) + 60 J (thermal) = 150 J.
Remaining for sound = 180 J − 150 J = 30 J.

Answer: 30 J.
