Carroll & ostlie an introduction to modern astrophysics for the monochromatic ux of cygnus a at different wavelengths: a) make a graph of log10(f) vs. and determine the value of the spectral index at log10() = 8 for the power law given in equation 1 (chapter 28, carroll & ostlie). b) use a simple trapezoid rule to investigate the area under the curve of f vs. for the data given, and use your answer to estimate the radio luminosity of cygnus a. hint: note, in part (b) you are integrating under the curve of f vs. not log10(f) vs. the distance to cygnus a is mpc (use h = 0.71).

Asquare isothermal chip is of width w=5 mm on a side and is mounted in a substrate such that its side and back surfaces are well insulated; the front surface is exposed to the flow of a coolant at tinf=15 °c. from reliability considerations, the chip temperature must not exceed t=85 °c. if the coolant is air and the corresponding convection coefficient is h=200 w/m2 x k, what is the maximum allowable "power" of the chip? if the coolant is a liquid for which h=3000 w/m2 x k, what is the maximum allowable power of the chip?
