Because of the lower pressure in a small area, the atmospheric pressure outside pushes down on it and holds it firmly in place. Suction cups will hold on until either the cup is lifted from the side allowing air in and makes pressures equal or by applying a force large enough to overcome atmospheric pressure. http://www.kingfar.com.hk/Suction-Plasti...
Indeed. It relies on negative fluid pressure of air (or water) to adhere to nonporous surfaces, creating a partial vacuum. The force needed to pull it apart is determined by the area of the cup and the pressure (typically normal atmospheric pressure).
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.
