Dunno, you've not given us sufficient data. EX: I have a balloon inflated the size of a bowling ball. They displace the same volume of air.
Are they the same density? Which is less? EX: I have a bowling ball and a cue ball, each with the same density.
Which displaces more air? Think you best review the definitions for mass density.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
