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).
In fact, other than mercury, water has the greatest surface tension of any liquid. (Source: Lakes of Missouri) Within a body of a liquid, a molecule will not experience a net force because the forces by the neighboring molecules all cancel out (diagram).
