Answer:

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.

How are dwarf planets different from true planets?
morpeh [17]

Answer:

The only difference between a planet and a dwarf planet is the area surrounding each celestial body. A dwarf planet has not cleared the area around its orbit, while a planet has.

Explanation:

the three criteria of the IAU for a full-sized planet are: It is in orbit around the Sun. It has sufficient mass to assume hydrostatic equilibrium (a nearly round shape). It has "cleared the neighborhood" around its orbit .

Give examples of not useful high friction
Tatiana [17]
Friction can be bad by being too strong or too weak. 

<span>Sometimes, when it is too strong, it decreases efficiency since some energy is wasted and turns to heat. Friction can also d</span><span>amage equipment/objects like when you slide it on the floor.
</span>
When friction is too weak, like for instance when there is black ice- our center of gravity is displaced too quickly and we can fall. Likewise, if there is a lot of slush on the ground, cars can slip and slide.
