Your friend decides to generate electrical power by rotating a 100,000 turn coil of wire around an axis in the plane of the coil and through its center. the coil is perpendicular to earth's magnetic field in a region where the field strength is equal to 0.300 g. the loops of the coil have a radius of 28.0 cm, and the coil has negligible resistance.
(a) if your friend turns the coil at a rate of 140 rev/s, what peak current will exist in a 1400 o resistor that is connected across the terminals of the coil?
ma
(b) the average of the square of the current will equal half of the square of the peak current. what will be the average power delivered to the resistor?

Carbon is allowed to diffuse through a steel plate 15 mm thick. the concentrations of carbon at the two faces are 0.65 and 0.30 kg c/m^3 fe, which are maintained constant. if the preexponential and activation energy are 6.2 x 10-7 m2 /s and 80,000 j/mol, respectively, compute the temperature at which the diffusion flux is 1.43 x 10^-9 kg/m^2 -s.
