Physics

A) The resistivity of blood is related to its hematocrit, thevolume fraction of red blood cells in the blood. A commonly usedequation relating the hematocrit h to the blood resistivity ρ (inΩ⋅m) is ρ=1.32/(1−h)−0.79. In one experiment, blood filled agraduated cylinder with an inner diameter of 0.90 cm. Theresistance of the blood between the 1.0 cm and 2.0 cm marks of thecylinder was measured to be 246 Ω. What was the hematocrit for thisblood?

B) When the starter motor on a car is engaged, there is a 310 AAcurrent in the wires between the battery and the motor. Suppose thewires are made of copper and have a total length of 1.2 mm . Whatminimum diameter can the wires have if the voltage drop along thewires is to be less than 0.60 VV ? Express your answer inmillimeters.

C) Variations in the resistivity of blood can give valuableclues to changes in the blood's viscosity and other properties. Theresistivity is measured by applying a small potential differenceand measuring the current. Suppose a medical device attacheselectrodes into a 1.5-mmmm-diameter vein at two points 5.0 cmcmapart. What is the blood resistivity if a 8.8 VV potentialdifference causes a 220 μAμA current through the blood in the vein?Express your answer in ohm meters.
