Two stationary positive point charges, charge 1 of magnitude 3.05nC and charge 2 of magnitude 1.75nC , are separated by a distance of 44.0cm . An electron is released from rest at the point midway between the two charges, and it moves along the line connecting the two charges.

What is the speed vfinal of the electron when it is 10.0cm from charge 1?

Express your answer in meters per second.

An engine operates with four essential variables controlling its operation. For the engine to be operating properly, at least two of its control variables must be present at the same time. However, when the machine is not operating correctly, we wish to have some signal to alert us to the problem. Design a circuit to implement the state when the alarm signal is present

Bonnie and Clyde are married and have purchased a comprehensive major medical policy which covers them and their two sons, Smith and Wesson. The policy has a $500 calendar year family deductible, a $2,500 stop-loss provision, and an 80% co-insurance clause. The following losses occur: On January 1, 2013 Bonnie was treated for an infection at a cost of $200, on July 1, 2013 Smith was treated for an injury suffered while waterskiing at a cost of $10,000, on December 5, 2013 Clyde underwent eye surgery at a cost of $1,500, and on January 5, 2014 Wesson was treated for a broken leg at a cost of $2,000. How much will the insurer pay for each of these losses?

The mean cost of domestic airfares in the United States rose to an all-time high of $375 per ticket. Airfares were based on the total ticket value, which consisted of the price charged by the airlines plus any additional taxes and fees. Assume domestic airfares are normally distributed with a standard deviation of $115. Use Table 1 in Appendix B.

a. What is the probability that a domestic airfare is $560 or more (to 4 decimals)?

b. What is the probability that a domestic airfare is $240 or less (to 4 decimals)?

c. What if the probability that a domestic airfare is between $320 and $480 (to 4 decimals)?

d. What is the cost for the 5% highest domestic airfares? (rounded to nearest dollar)

Andretti Company has a single product called a Dak. The company normally produces and sells 81,000 Daks each year at a selling price of $42 per unit. The company’s unit costs at this level of activity are given below:

A number of questions relating to the production and sale of Daks follow. Each question is independent.

Required:

1-a. Assume that Andretti Company has sufficient capacity to produce 113,400 Daks each year without any increase in fixed manufacturing overhead costs. The company could increase its unit sales by 40% above the present 81,000 units each year if it were willing to increase the fixed selling expenses by $140,000. What is the financial advantage (disadvantage) of investing an additional $140,000 in fixed selling expenses?

1-b. Would the additional investment be justified?

2. Assume again that Andretti Company has sufficient capacity to produce 113,400 Daks each year. A customer in a foreign market wants to purchase 32,400 Daks. If Andretti accepts this order it would have to pay import duties on the Daks of $2.70 per unit and an additional $29,160 for permits and licenses. The only selling costs that would be associated with the order would be $1.70 per unit shipping cost. What is the break-even price per unit on this order?

3. The company has 500 Daks on hand that have some irregularities and are therefore considered to be "seconds." Due to the irregularities, it will be impossible to sell these units at the normal price through regular distribution channels. What is the unit cost figure that is relevant for setting a minimum selling price?

4. Due to a strike in its supplier’s plant, Andretti Company is unable to purchase more material for the production of Daks. The strike is expected to last for two months. Andretti Company has enough material on hand to operate at 25% of normal levels for the two-month period. As an alternative, Andretti could close its plant down entirely for the two months. If the plant were closed, fixed manufacturing overhead costs would continue at 35% of their normal level during the two-month period and the fixed selling expenses would be reduced by 20% during the two-month period.

a. How much total contribution margin will Andretti forgo if it closes the plant for two months?

b. How much total fixed cost will the company avoid if it closes the plant for two months?

c. What is the financial advantage (disadvantage) of closing the plant for the two-month period?

d. Should Andretti close the plant for two months?

5. An outside manufacturer has offered to produce 81,000 Daks and ship them directly to Andretti’s customers. If Andretti Company accepts this offer, the facilities that it uses to produce Daks would be idle; however, fixed manufacturing overhead costs would be reduced by 30%. Because the outside manufacturer would pay for all shipping costs, the variable selling expenses would be only two-thirds of their present amount. What is Andretti’s avoidable cost per unit that it should compare to the price quoted by the outside manufacturer?

c++ problem:

Implement a class money. You must have friend functions for I/O that overload << and >>. You must have multiple constructors, You must implement a percentage method,+,-, <,>. There is a starting money class in your text.

Example output:

Enter an amount of money: $14.33

Your amount is $14.33

My amount is $10.09

One of us is richer.

You have more money than me.

10% of your money is: $$1.43

$14.33 + $10.09 equals $24.42

$14.33 - $10.09 equals $4.24

Consider a model in which M balls are distributed between two bins, and at each time point one of the balls is chosen at random and is then removed from its bin and placed in the other one. Let Xn denote the number of balls in bin 1 after the nth switch and let m_n = E[Xn].

(a) Classify all the states of this chain as recurrent or transient (justify your answer!)

(b) Find E[X2|X0 = 2]

Can you think of a way of performing soft lithography on curved surfaces like a glass optical fiber? Why would you want to do that?

Soft lithography is inherently a 2D printing technique, can you think of a way to taking to the third dimension? Why would this capability be useful?

Precisely 15 years ago (you have just made the 180th monthly payment) you took out a traditional, fixed rate 30-year mortgage for $300,000 at 7.20% APR. You are considering whether to refinance this loan and replace it with a fixed rate 15-year mortgage (assume an identical timing of the remaining payments). The closing costs are $3,000, which you intend to borrow. Disregarding the psychic cost of the process, please find the breakeven interest rate (i.e. the rate at which you would be indifferent between refinancing vs. keeping the existing mortgage). Express your answer as an APR with 3 digits after the decimal point.
