If the trier of fact has no doubt as to the defendant's guilt, or if their only doubts are unreasonable doubts, then the prosecutor has proved the defendant's guilt beyond a reasonable doubt and the defendant should be pronounced guilty.
Surface tension is the elastic tendency of liquids which makes them acquire the least surface area possible. Surface tension is an important property that markedly influences many ecosystems.t liquid-air interfaces, surface tension results from the greater attraction of liquid molecules to each other (due to cohesion) than to the molecules in the air (due to adhesion).
If the surface is stretched-as when you blow up a bubble-it becomes larger in area, and more molecules are dragged from within the liquid to become part of this increased area. This stretchy skin effect is called surface tension. Surface tension plays an important role in the way liquids behave.
