Read "Booker T. Washington & W. E.B. DuBois on Black Progress (1895, 1903)" and respond to the following questions. Make sure to reference specific passages from the document and/or textbook to support your discussion 1. According to Washington, how should African Americans respond to systemic racial discrimination?
2. What does Washington mean when he says that "the agitation of questions of social equality is the extremest folly?"
3. What does DuBois think of Washington's plan to uplift African Americans? What, according to DuBois, has been the result of following Washington's advice?

A3-mm-thick panel of aluminum alloy (k 177 w/m-k, c 875 j/kg-k and ? = 2770 kg/m) is finished on both sides with an epoxy coating that must be cured at or above t,-150°c for at least 5 min. the production line for the curing operation involves two steps: (1) heating in a large oven with air at ts,0-175°c and a convection coefficient of h, 40 w/m2. k, and (2) cooling in a large chamber with air at 25°c and a con- vection coefficient of he 10 w/m2.k. the heating portion of the process is conducted over a time interval te which exceeds the ime required to reach 150°c by 5 min (h = r + 300 s). the coating has an emissivity of ? = 0.8, and the temperatures of the oven and chamber walls are 175 and 25°c, respectively. if the panel is placed in the oven at an initial temperature of 25°c and removed from the chamber at a safe-to-touch tempera ture of 37°c, what is the total elapsed time for the two-step curing operation?
