A wire of radius r = 1mm carries a current of I = 0.314 X 3.2 A. the wire is made from a metal of mass density ρ= 10 gr/cm3, the atomic mass unit of the metal is 60gr. Note that 1 mole of this metal contains 6 X 1023 free electrons, the charge of the electron is e = 1.6 X 10 -19 C. Determine the drift velocity of the free electron using this equation j = -nev

Suppose that a new machine is installed that increases the hourly output of labor as follows: Labor 1, output 16; labor 2, output 34; labor 3, output 50; labor 4, output 64; labor 5, output 78; labor 6, output 90. Also assume that all firms in the industry install this machine: The increased demand for labor raises the hourly wage to $6 per hour and the market equilibrium price for the output falls to $0.50. What is the new profit maximizing quantity of labor per hour?

Refer to this text to answer the following question. To map genes of a bacterial strain, conjugation must be interrupted at given times. Suppose you have Hfr cells of genotype a+b+c+d+e+strR and F= cells of genotype a-b-c-d-e-strS and you combine these two cultures in liquid medium in four blenders at time 0. After intervals of 3, 6, 9, and 12 minutes, you turn on successive blenders. The resulting cultures were then plated on medium containing streptomycin. Why?
