A current =2 A flows in the inner conductor of an infinitely long coaxial line and returns via the out conductor. The radius of the inner conductor is a = 0.5 mm, and the inner and outer radii of the outer conductor are b = 1.8 mm and c = 2 mm, respectively. Find the magnetic flux density (in μT, one decimal point) at a distance r=[x] mm from the center of the inner conductor.

Assume that 150 turns of wire are tightly wound on a toroidal frame of a rectangular cross-section with a = 2 mm, b=4 mm, and h= [x] mm. Then, assuming the permeability of the medium to be , find the self-inductance (in μH, one decimal point) of the toroidal coil.

A 100 million gallon annual capacity ethanol plant is being planned. Ethanol (C2H5OH) is to be produced from locally grown switchgrass using a lignocellulosic fermentation technology (biochemical platform). Switchgrass is harvested once annually, contains 30% moisture and crop yield (includes moisture at harvest) is 14,000 kg/hectare. Average organic composition of switchgrass on dry basis is as follows: Cellulose (C6H10O5) = 45%; Hemicellulose (CH1.6O0.8) = 15%; Lignin= 15%; Ash= 8%; Extractives= 17%. Write balanced stoichiometries for the microbial conversion of cellulose and hemicellulose to ethanol. Using the above stoichiometries, calculate the ethanol yield from cellulose and hemicellulose in g/g. What is the yield of ethanol from switchgrass as harvested? Express this yield in L per metric tonne. How much switchgrass as harvested is required annually as feedstock for the plant? Assume 100% conversion of sugars and no losses during processing. Calculate the land area in hectares required to grow switchgrass that will meet the demand of the ethanol facility.

After hearing that a local tire company was looking for a new firm to handle their advertising, Kevin scheduled a sales presentation to try to persuade the company to sign on with his advertising business. For the presentation, Kevin wanted to use a style of delivery that would enable him to cover all his prepared material in an organized way, yet would still appear spontaneous. Which delivery method should Kevin select for his presentation?
