A Bluetooth speaker used 573 J of energy while playing music. If it produces 356 J of sound energy, what is the efficiency of the speaker in transforming electrical energy into sound energy? Show all your work.

The efficiency of the Bluetooth speaker is 62.13 %.

Explanation:

Given;

input electrical energy of the Bluetooth speaker, = 573 J

output sound energy of the Bluetooth speaker, = 356 J

The efficiency of the Bluetooth speaker in transforming electrical energy into sound energy is given by;

Therefore, the efficiency of the Bluetooth speaker is 62.13 %.
