Variations in the resistivity of blood can give valuable clues about changes in various properties of the blood. Suppose a medical device attaches two electrodes into a 1.8-mm-diameter vein at positions 4.8cm apart. What is the blood resistivity if a 9.0 V potential difference causes a 280?A current through the blood in the vein?

ρ = 1.70 Ωm

Explanation:

given data

diameter = 1.8 mm

distance = 4.8 cm

volt = 9 V

potential difference = 280

solution

we know that Resistance that is express as

Resistance =     ..............1

V = I × R

and

V = I  ×    ..........2

put here value we get

9 = 280 × ×  

ρ = 1.70 Ωm

to be honest as much as i would love to answer this. i feel as if something's missing. just saying.

answer:   you might love summer weather, but you don’t want it to feel like the sun is inside your car. but a hot car that just won’t seem to cool down might be a bigger of a problem than you think. your car relies on being at the right temperature.
