6. ( 2 pts) The resistivity of copper is about $ 1.7 \times 10^{-8} \Omega-\mathrm{m} .16 $-gauge wire has a diameter of 1.3 mm . You plan to use 16 -gauge copper wire to connect your stereo to a speaker with resistance of $ 8 \Omega $. We will assume here that the current is flowing uniformly through the entire cross section of the wire, though this is not actually the case. a. What is the longest this wire can be so that its resistance is less than $ 1 \% $ that of the speaker? b. At some instant the speaker is drawing 2 A of current. What is the voltage across the speaker at this time? c. What is the current density in the wire at this time?

Why might knowledge of the gene and protein sequences of a species be useful in classifying that species? It would keep the species from being interbred with any other species that might appear physically similar to it. It would make it possible to compare that species to other species at a level deeper than outward appearance. It would allow more accurate naming of the species by basing names on genes rather than appearance. It would prove that all the members of a given species were genetically identical to each other.
