Calculate the value of the current through the point. I=Q/t = 1C/20s = .05C/s= .05 A x10^-3 C = 50mA 2.A total charge of 2.5 × 10-3 C passes a point every 40 seconds. Calculate the value of the current through the point. I=Q/t =0.0025C/40s= 6.25 C/s = 6.25 A 4.A total charge of 50 × 10-3 C passes a point

for the Ambassador China project. This calculation uses the following assumptions: 1. Calculations are done on a nominal basis‚ converting the salvage value estimate from a real to a nominal value (638 = 500(1.05)5) using the 5% inflation estimate; salvage = book value so no taxes are incurred on salvage. 2. Depreciation is calculated at [4‚000 – 638 (salvage) ]/ 5 = 672.4 per year. 3. Cars sales occur in year 1

Problem-Solving Exercise 1 1. In your own words‚ explain what density altitude is and how it affects your airplane. Density altitude‚ or "Pressure Altitude"‚ is the density of air given as a height above Mean Sea Level (MSL). Density altitude affects the wings ability to create lift‚ the aircrafts propeller to create thrust and the power output of the engine. 2. In your own words‚ explain the theory of lift and what basic laws are involved. In my opinion lift can be explained by

Problem #1 A. How many newspapers should Sheen stock? Use the simulation in the spreadsheet “Hamptonshire Express: Problem #1” to identify the optimal stocking quantity. What is the profit at this stocking quantity? Optimal Stocking Quantity: 584 Expected profit at Optimal Stocking Quantity: $331.43 B. Verify that the value derived in part (a) is consistent with the optimal stocking quantity in the Newsvendor model = mean = 500 = Standard Deviation = 100 = Overage Cost = $0

Week 5 – Financing Strategy Problem Problem 1 – Chapter 20 Firm A has $10‚000 in assets entirely financed with equity. Firm B also has $10‚000 in assets‚ but these assets are financed by $5‚000 in debt (with a 10 percent rate of interest) and $5‚000 in equity. Both firms sell 10‚000 units of output at $2.50 per unit. The variable costs of production are $1‚ and fixed production costs are $12‚000. (To ease the calculation‚ assume no income tax.) A. What if the operating income (EBIT)

Applied Problem 3 - 1 Chapter 5: Applied Problem 1 Bridget has limited income and consumes only wine and cheese; her current consumption choice is four bottles of wine and 10 pounds of cheese. The price of wine is $10 per bottle‚ and the price of cheese is $4 per pound. The last bottle of wine added 50 units to Bridget’s utility‚ while the last pound added 40 units. a) Is Bridget making the utility-maximizing choice? Why or why not? In simplest terms wine is 50 units/$10 = 5 and cheese is 40
