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).
Surface tension has the dimension of force per unit length, or of energy per unit area. The two are equivalentâbut when referring to energy per unit of area, people use the term surface energy âwhich is a more general term in the sense that it applies also to solids and not just liquids.urface tension has the dimension of force per unit length, or of energy per unit area.
