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).
Formally, surface tension is deï¬ned in much the same way as pressure was deï¬ned inequation (2.10) on page 24. Let an oriented open surface be divided into two parts by anoriented curve, such that the surface has a uniquely deï¬ned left and right hand side withrespect to the curve.
