Which prediction will most likely describe how friction will affect her findings?

The distance for Trial 3 will be greater than the distance for Trial 4 because the difference in surface roughness will affect friction.

Explanation:

1 a

2 d

3 a

4 c

explanation:

a  solution  is always transparent, light passes through with no scattering from solute particles which are molecule in size. the  solution  is homogeneous and does not settle out. a colloid is intermediate between asolution  and a  suspension. while asuspension  will separate out a colloid will not.
