Ann propped up a graham cracker in a shallow bowl. she then set up an electric fan to blow on the graham cracker at three different speeds. what is anns dependent variable in this experiment?

Graham cracker

Explanation:

An independent variable can be changed, altered and manipulated in an experiment to determine the effect of this on the dependent variable. The dependent variable or experimental variable undergoes changes due to the effective changes in the independent variable.

In the given situation, the electric fan three different speeds is the independent variable whose effect is to be determined on the graham cracker, which is a dependent variable.  

both adhesion and cohesion are attractions.

they are different in that adhesion is the force of attraction between the molecules of two different substances, whereas cohesion is the force of attraction between molecules of the same substance.

possible examples include capillary action, in which the adhesion between water and glass causes the water to rise in a narrow tube against the force of gravity.

because of hydrogen bonding, water is extremely cohesive.

this causes molecules on the surface of water to be drawn inward, which is why drops of water form beads on smooth surfaces.

hope this .

the answer would be b i believe
