Three children are sitting on a merry-go-round while a fourth child is pushing on the outside edge with a constant force. Why does it take less time for the fourth child to speed the merry-go-round up if the three other children all sit in the center rather than halfway between the center and outside edge

i guess that visual aids present persuasive examples to what you are presenting, some factors would be theme (does it fit with the color, information, what you are presenting), size (can you see it, is it a big enough span of data/information), and overall look of the visual aid.

hope this : )

i need the answer to this too but idk it ; -;
