Two-dimensional, steady-state conduction occurs in a hollow cylindrical solid of thermal conductivity 14 w/m·k, outer radius 1 m and overall length 5 m, where the origin of the coordinate system is located at the midpoint of the center line. the inner surface of the cylinder is insulated, and the temperature distribution within the cylinder has the form , where -20°c, 150°c/m2, -14°c, -300°c/m2 and and are in meters. (a) determine the inner radius of the cylinder. (b) determine the volumetric rate of heat generation, (c) determine the axial distribution of the heat flux at the outer surface, what is the heat rate at the outer surface? is it into or out of the cylinder?

You have two photos of a person walking. one shows the person at the corner of third and main streets, the other shows the person at the corner of tenth and main streets. there are lampposts at every corner in this town, and the first picture shows it to be 10: 32: 00 exactly. the second picture shows it to be 10: 49: 30. you know three facts: (1) all of the clocks are synchronized; (2) there are exactly 12 equal-sized blocks per kilometer in this town; and (3) the streets that cross main in this area are numbered consecutively, with no interruptions. what is the person’s average speed in kilometers per hour?
