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?

A. 30 J
B. 90 J
C. 150 J
D. 330 J

Answer :

The sound energy generated by the blender is 30 Joules. Option A is correct.

Given the following information

Total electrical energy is 180 Joules

Amount transformed into kinetic energy is 90J

Amount transformed into thermal energy is 60J

If the rest is transformed into sound, the amount transformed is expressed as:

Amount transformed into sound = 180 - (90 + 60)

Amount transformed into sound = 180 - 150

Amount transformed into sound is 30Joules
