Adrop of water placed on a smooth, dry surface will form a dome-shaped droplet instead of flowing outward in different directions. which of these best explains this observation?
a. the bonds between hydrogen and oxygen atoms are too strong.
b. the electrons in the atom attract the electrons in other atoms.
c. water molecules at the surface experience fewer hydrogen bonds than water molecules within the liquid
d. water molecules near the surface produce more buoyant force than water molecules within the liquid.

Alice did an experiment to find the relationship between the angle at which a ray of light strikes a mirror and the angle at which the mirror reflects the light. she placed a ray box in front of a mirror. she changed the angle at which the light from the ray box struck the mirror and noted the corresponding angle at which the mirror reflected the light. which of the following is the dependent variable in this experiment? the mirror used to reflect the light the ray box used as the source of light angle at which the light from the ray box strikes the mirror angle at which the mirror reflects the light from the ray box
