Answer:
Diffusion rate is 1.96 × 
/s
Explanation:
Diffusion is the process in which the molecules of a substance propagates from a region of higher concentration to region of lower concentration through a semi-permeable membrane.
diffusion rate = 
Given that; diameter = 15 mm, time = 15 minutes.
The dye spread in a circular form, so that;
area = 
r = 
= 
= 7.5 mm = 0.75 cm
area = 
× 
= 1.7679
time = 15 minutes = 15 × 60 = 900 seconds
So that;
diffusion rate = 
= 0.0019643 /s
Diffusion rate is 1.96 × /s
Answer:
it may be erosion, I'm not quite sure but it could possibly be a form of erosion.
The correct answer is Mountain Peak.
When multiple glaciers start flowing downward, they create a pyramid like structure. This movement of glacier from a single point results in the formation of the mountain peak. A pointed structure is just formed due to the simultaneous movement of multiple glaciers to the ground. The cliff is not formed by the slipping down of glacier from single point.
