2. Problem 1.15. from the book. [Statement: The pressure difference, Δp, across a partial blockage in an artery (called a stenosis) is approximated by the equation: ∆P = Kv μV D + Ku ( A0 A1 − 1) 2 rhoV 2 where V is the blood velocity, μ the blood viscosity (FTL-2 ), rho the blood density (ML-3 ), D the artery diameter, Ao the area of the unobstructed artery, and A1 the area of the stenosis. Determine the dimensions of the constants KV and Ku. Would this equation be valid in any system of units?]

The coulomb's law explains which of the following? select all the force between two charged objects is inversely proportional to the charge on each object. the force between two charged objects is directly proportional to the charge on each object. the force between two charged objects is directly proportional to the distance separating them. the force between two charged objects is inversely proportional to the square of the distance separat coulomb's law is similar to newton's 2nd law. if the force between two objects is f and the charge on both objects is doubled, the new force between the would now be 2f. if the force between two objects is 2f and the distance separating them is doubled, the new force between the objects would now o the be zf.
