However, after the interview, you personally research more on the company and their clients, and begin to suspect that the stress measurement equipment is used in interrogation of high value suspects. If this were an ethics exam (which it isnt) you would be asked to discuss the issues involved in this application of biomedical engineering. However, if you have time to consider the ethics, please refer to the last (bonus) question. You may use the following equations and constants: E = mc 2 R c = (8 L ) / ( r 4 ) E = E + RT nF lna c Electron Charge: 1 . 6 10- 19 Coul c = 3 10 8 m s L c = ( L ) / ( r 2 ) R = 8 . 31 J K mol Atmospheric Pressure: 101 . 3 kPa F = ma C = ( Coul ) / ( V ) F = 9 . 65 10 4 Coul mol 1 mol = 6 . 02 10 23 particles V = IR P ( V N ) = Const dV + V P dP = 1 dN Blood Resistivity: b = 450 cm air = 1 . 21 kg m 3 blood = 1060 kg m 3 air = 1 . 8 10- 6 Pa s blood 3 . 10- 3 Pa s 1.
