Calculating Efficiency. Efficiency (%) = Useful Energy Out x 100 Total Energy In Questions 1) A light bulb takes in 30J of energy per second. It transfers 3J as useful light energy and 27J as heat energy. Calculate the efficiency. 2) A kettle takes in 2000J of energy per second. It transfers 1500J as useful heat energy and 500J is wasted as sound energy. Calculate the efficiency of the kettle. Remember: In the exam they may not

Pareto efficiency‚ or Pareto optimality‚ is a central theory in economics with broad applications in game theory‚ engineering and the social sciences. Given a set of alternative allocations and a set of individuals‚ a movement from one alternative allocation to another that can make at least one individual better off‚ without making any other individual worse off is called a Pareto improvement or Pareto optimization. An allocation of resources is Pareto efficient or Pareto optimal when no further

Miguel Felix pGLO Transformation Mr. Betz AP Biology 14 December 2012 Abstract The purpose of this experiment is to determine the effects of the addition of a plasmid to a bacterial cell. The bacteria E. Coli was separated into two groups: one where the pGLO plasmid was added to the bacteria‚ which contains the genes of fluorescence and resistance to antibiotics‚ and the other lacking the plasmid. The two groups then placed in agar plates simulating different environments: the bacteria lacking

Efficiency Ratios The efficiency ratio is an indicator of how well Johnson and Johnson (J&J) is run on an organizational wide basis. Efficiency ratios are also defined as asset turnover ratios (Finkler‚ Kovner & Jones‚ 2007). The asset turnover ratio measures how productive J&J is in managing all of its assets to generate Sales. This efficiency ratio is calculated by dividing sales by total assets by total revenue. For year 2010‚ J&J had an asset turnover of 0.6. Comparing J&J’s

Sessions 6‚ 7 & 8 Economic Efficiency y Consumer Surplus A buyer’s willingness to pay (WTP) for a good p y( ) g is the maximum amount the buyer will pay for that good good. WTP measures how much the buyer values the good. Example: 4 buyers’ WTP for an iPod name Anthony WTP $250 Chad 175 Flea 300 John 125 Consumer Surplus Q: If price of iPod is $200‚ who will buy an iPod‚ and what is quantity demanded? q y A: Anthony & Flea will buy
