Acylindrical blood vessel is partially blocked by the buildup of plaque. at one point, the plaque decreases the diameter of the vessel by 69.0 %. the blood approaching the blocked portion has speed v 0 . just as the blood enters the blocked portion of the vessel, what is its speed v , expressed as a multiple of v 0

10.4 times of initial velocity

Explanation:

Given

Diameter reduced by 69 %

it approaches with velocity

suppose its velocity is v during blocked passage

suppose d is the initial diameter and diameter is

As flow is constant

this could be newton#'s law of cooling. the cooling curve is exponential

as we know our atmosphere or air have different levels. every level has other gasses, and every gas has another permeability. when the light comes from lower permeability to higher permeability, it changes its direction. so that means that when the light comes from the moon to the earth, it changes it's direction many more times. it basically means that the shape of the light part of the moon is changed on the earth.
