A number of fast food chains, after their success with offering their customer fresh salads and in an effort to downplay the image of selling unhealthy food, began adding fresh fruit plates to their menus. At about the same time, and seemingly in direct conflict with this “healthy†strategy, several other fast food chains began offering fat and calorie laden...

Determine the energy density due to an isolated, charged spherical conductor of radius R at each point in space as a function of the distance r from the sphere’s cen- ter. (b) Use this energy density to compute the system’s total energy. (c) Compare this total energy to the expression found by treating the sphere as a capacitor.

Draw a map of cellular level processes including: protein synthesis, photosynthesis (include chemical equation), cellular respiration (include chemical equation), mitosis including DNA replication, meiosis including crossing over, and processing involving the cell's environment. Be sure all processes are interconnected---there should be no isolated systems or processes.
