local stores based on forecast sales or the hope of making more sales by flooding isles with products (“push” driven supply chains). In the case of Walmart‚ the supply chain is driven by consumer behavior which “pulls” replacement stock from inventory. 2. Why is a detailed knowledge of consumer purchases at each store important to Walmart’s success? There are regional and local differences among all of Walmart’s stores in the United States. These differences may involve weather patterns‚ ethnic composition

positive integer‚ r = distance of electron from center‚ m = mass of electron. Solve‚ get mvr = L = nh/2pi. (b) The current wave mechanical model for the atom states that there are an integer number of wavelengths in every standing integer number (n). 2. (a) The first shell electrons in Lithium are the closest electrons to the nucleus. In addition‚ there are proportionally more protons to electrons. This pulls the electrons even closer to the nucleus. And in Potassium‚ the outer shell electrons are

to break it down the cell will die‚ along with the organism itself. However with the aid of an enzyme‚ catalase‚ hydrogen peroxide is able to be broken down into an intermediate and thereafter harmless substances water and oxygen. The goal of this lab is to measure the reaction rate of this process in different substances such as a liver‚ a vegetable‚ and breast tissue. By using variables such a pH and temperature we are able to how the rate of reaction is altered or improved. If it has improved

Shake each test tube gently and record any change that takes place in the aqueous layer over about 5 minutes. Reaction of hydrocarbons with bromine water: 1) Into three separate‚ labeled test tubes place 1 ml of cyclohexane‚ cyclohexene and toluene respectively. 2) Add 1 ml of bromine water

Unit 2 Research Paper 1: Experiment A problem that I think needs to be solved is traffic lights causing the back up of traffic. Traffic lights cause a delay in traffic and cause for traffic back up. It causes everyone to be late when there is no need for it. From personal experience I have been late of several occasions due to backed up traffic because of traffic lights. There are certain spots where traffic lights are not needed and they are only backing up traffic more than needed. Traffic lights
