AnnZ [28]

Answer:

A; the reason why a balloon stuck to the wall was that it was electrically charged (negativly). when you put it by the wall it pushes the negative particles in the wall away and pulls the positive particles closer so that it sticks to them.

B; the reason for this is because of gravity. according to Einstein's General Theory of Relativity gravity is warpiture in spacetime which makes mass fall towards other mass.

C; this is because as the amount of oxygen in the air decreases and the air becomes drier, blood vessels inside your nose can crack and bleed. as you get higher the amount of air becomes proportionally less because there is less gravity to hold it down to the earth.

D; this is because the tallest buildings way a tone or many many tones which creates a lot of pressure where it sits. the reason they have wide foundations so that the pressure is spread out.

E; anyone who is around different amounts of air and different amounts of pressure will need a special suit so that their bodies can function as they would in their normal environment.

F; the bottom of a dam needs to be much stronger than the top because all of the pressure from the water on top gets channeld to the bottom.
