In a post office, a 3-m long ramp is used to move carts onto a dock that is higher than 1 m. which describes how the ima of this ramp compares with the ima of the ramp that has a height of 1 m? it is greater. it depends on friction. it is the same. it is less.

well I think the answer is it depends on the friction

a. hope i'm right

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.
