Question

Physics

a. Use Faraday’s Law to derive the expression for the inducedEMF for an ordinary slide generator, being careful to explain thesteps, like on an exam.
b. Use that to estimate the EMF generated across the wingspanof an airplane flying toward Minnesota. Use the same 55.66 μTpointed 70 degrees downward.
The wing span is 35.78 meters and cruising speed is 907km/h.
c. First conceptual question. There is obviously not a circuitor a current for a real airplane. Does that mean there actually isno EMF, or if you are sure there is an EMF, explain (with a carefuldiagram) the non-Faraday reason that causes it.
d. Second conceptual question. Even though the voltage is muchsmaller than (about 1/10th) what a real electronic device woulduse, assume you want to use this voltage anyway. You propose astrategy to connect a copper wire from each wingtip to your
device and get current and energy to flow, and realize itwon’t work because it is like the example in class with a squareloop in a uniform field. Explain.
