Considerable scientific work is currently under way to determine whether weak oscillating magnetic fields such as those found near outdoor electric power lines can affect human health. one study indicated that a magnetic field of magnitude 1.40 ✕ 10^−3 t, oscillating at 60 hz, might stimulate red blood cells to become cancerous. if the diameter of a red blood cell is 7.8 μm, determine the maximum emf that can be generated around the perimeter of the cell.

An ideal otto cycle has a compression ratio of 8. at the beginning of the compression process, air is at 95 kpa and 27°c, and 750 kj/kg of heat is transferred to air during the constant-volume heat-addition process. assuming constant specific heats at room temperature, determine (a) the pressure and temperature at the end of the heat-addition process, (b) the net work output, (c) the thermal efficiency, and (d) the mean effective pressure for the cycle. (4390 kpa, 1730 k; 423 kj/kg; 56.4%; 534 kpa)
