a.Estimate the electrical resistance of the blood in a 50cm long, 3mm diameter artery. The resistivity of blood is 1.6 ohm-meter.Express your answer in cΩ, mΩ,μΩ, and nΩ. B. Suppose the energy for two doughnuts in Thermodynamics are totally converted into electric potential energy at point a, wherein a dust particle of 5 × 10-9 kg with 9nC charge is travelling from point a with 600 m/s to point b (where there is no electric potential energy). How fast does the dust particle is moving at point b?
