A student placed 17.0 of glucose () in a volumetric flask, added enough water to dissolve the glucose by swirling, then carefully added additional water until the 100.-mark on the neck of the flask was reached. The flask was then shaken until the solution was uniform. A 35.0- sample of this glucose solution was diluted […]
A steel pipe with 5-cm OD is covered with a 6.4-mm asbestos insulation[k = 0.096 Btu/h · ft · ◦F] followed by a 2.5-cm layer of fiberglass insulation[k = 0.028 Btu/h · ft · ◦F]. The pipe-wall temperature is 315◦C, and the outside insu-lation temperature is 38◦C. Calculate the interface temperature between the asbestosand fiberglass.

. A finite rod of length L has total charge q, distributed uniformly along its length. The rod lieson the x-axis and is centered at the origin. Thus one endpoint (x, y) is located at (−L/2, 0)and the other is located at (L/2, 0). Define the electric potential to be zero at an infinitedistance away […]
