Surface tension has the units of A. newtons/m2 B. newtons/cm C. newtons/m D. newtons

The correct answer is A. newtons/m2.

Surface tension is the force that acts at the surface of a liquid, trying to minimize the surface area. It is caused by the attraction of the molecules in the liquid to each other. The units of surface tension are newtons per meter squared (N/m2).

Option B, newtons/cm, is incorrect because the units of surface tension are not newtons per centimeter.

Option C, newtons/m, is incorrect because the units of surface tension are not newtons per meter.

Option D, newtons, is incorrect because the units of surface tension are not newtons.
