Variations in the resistivity of blood can give valuable clues to changes in the blood's viscosity and other properties. the resistivity is measured by applying a small potential difference and measuring the current. suppose a medical device attaches electrodes into a 1.5-mm-diameter vein at two points 5.0cm apart. what is the blood resistivity if a 8.9v potential difference causes a 240ua current through the blood in the vein?

Consider a uniformly charged ring in the xy plane, centered at the origin. the ring has radius a and positive charge qdistributed evenly along its circumference. a)what is the direction of the electric field at any point on the z axis? . b)what is the magnitude of the electric field along the positive z axis? use k in your answer, where k=14πϵ0. d)the ball will oscillate along the z axis between z=d and z=−d in simple harmonic motion. what will be the angular frequency ω of these oscillations? use the approximation d≪a to simplify your calculation; that is, assume that d2+a2≈a2. express your answer in terms of given charges, dimensions, and constants
