Surface tension . a. is the inward force which tends to minimize the surface area of a liquid b. may be increased by detergents c. is decreased by hydrogen bonding d.

Surface tension . a. is the inward force which tends to minimize the surface area of a liquid b. may be increased by detergents c. is decreased by hydrogen bonding d.

Note: option d is missing

The correct answer to the question is "option A (is the inward force which tends to minimize the surface area of a liquid)"

Explanation:

Surface tension is the most important for small fluid bodies. The surface comes under tension from the imbalanced forces  and is often expressed as an amount of force exerted in the surface perpendicular to a line of unit length and it is a direct measure of  energy loss per unit area of a surface.

The resistance that a surface shows against extension is a proof that an internal surface tension is present in the surface. Formula for measuring surface tension is: gamma equals force divided by length. The SI unit is newton per meter, dyne per centimeter is also used.

Water has a high surface tension because the water molecules on the surface are pulled together by strong hydrogen bonds. Surface tension of a liquid surface is that property of that liquid surface that makes it act like a stretched elastic sheet. Example of effect of surface tension on water is the flotation of objects denser than water, the separation of oil and water due to tension which arises in surface between dissimilar liquids. In the surface tension of liquid, the net force of attraction acting on the molecule is zero.

i think it because equal matrices have equal dimensions, only square matrices can be symmetric. for all indices and . every square diagonal matrix is symmetric, since all off-diagonal elements are zero. in linear algebra, a real symmetric matrix represents a self-adjoint operator over a real inner product space.
