Suppose that the build-up of fatty tissue on the wall of an artery decreased the radius of the artery from 10.0 mm to 7.22 mm. To maintain identical blood flow, by what numerical factor does the pressure differential provided by the heart increase compared to a normal artery (no fatty tissue build-up)?

Rank the six combinations of electric charges on the basis of the electric force acting on q1. define forces pointing to the right as positive and forces pointing to the left as negative. rank positive forces as larger than negative forces. q1,q2,q3 = positive(+) q1 = + q2 = + q3 = - q1 = + q2= - q3= + q1= - q2= + q3= + q1= + q2= - q3= - q1,q2,q3 = negative
