Which of the following is the correct definition of acoustic energy?
energy transmitted as sound waves
energy that is transmitted in the form of electromagnetic waves
energy of an object due to the random motion of its atoms and molecules
energy resulting from the flow of charge particles, such as electrons or ions

Question

Which of the following is the correct definition of acoustic energy?
energy transmitted as sound waves
energy that is transmitted in the form of electromagnetic waves
energy of an object due to the random motion of its atoms and molecules
energy resulting from the flow of charge particles, such as electrons or ions

What do you think?

yolo_king · Answer

We know that B isn't it, because we both know that Acoustic Energy is transferred with sound waves not electromagnetic waves.

yolo_king · Answer

C is inccorect because atoms and molecules have nothing to do with Acoustic Energy.

yolo_king · Answer

incorrect*

yolo_king · Answer

And same with D, ions and electrons have nothing to do with this subject cause acoustic energy is all about flow, pressure and velocity. So that leaves us with A being the answer :)

anonymous · Answer

Okay thank you the answer was right

anonymous · Answer

could you help me with some more please

yolo_king · Answer

Sure :)

anonymous · Answer

Acoustic energy is a form of
both potential and kinetic energy.
potential energy only.
kinetic energy only.
neither potential nor kinetic energy.

yolo_king · Answer

What do you think?

anonymous · Answer

A

yolo_king · Answer

Remember that acoustic energy is transferred by sound waves. What is potential energy?

anonymous · Answer

the energy possessed by a body

yolo_king · Answer

Yes potential energy is caused by electric charges, and our body's have that energy.

yolo_king · Answer

and kinetic energy is the motion of AIR molecules. So what do you think is the answer now?

anonymous · Answer

a

yolo_king · Answer

Remember that acoustic energy is caused by sound waves, Do you think sound waves have potential energy?

anonymous · Answer

yes

yolo_king · Answer

Nope they don't, think about it this way, Potential energy is the energy stored in something, like a person has energy to take a job, while the kinetic energy is the movement caused by that energy that is stored.

yolo_king · Answer

Think about it this way the boom box has potential energy and kinetic energy, the potential energy is the energy that is stared so that it can play music. 

While the kinetic energy is in the sound that is being released, the boom box releases air molecules.
