A dust particle is suspended in the air (floating due to a small updraft and its own low mass) when a powerful loudspeaker plays a very low note (2 Hz so it can’t be heard but you can actually see the speaker move!). How will the dust particle move as a result of the speaker 
being turned on? Question 3 options: A) The dust particle will move up and down. B) The dust particle will be pushed across the room. C) The dust particle will move in a circular path. D) The dust particle will move side to side.
