b) The recent global climate change has necessitated the need for a new model for predicting weather patterns. Two scientists who were modeling this process in Ghana ended up with two different system models.

i) What could be the possible reason(s) for the differences in their system model? Justify your answer.

ii) In relation to real world data from the process how can you select the best model to employ for subsequent simulations and prediction of the process?

def binsearch(a):
    if len(a) == 1:
        return a[0]
    else:
        mid = len(a)//2
        min1 = binsearch(a[0:mid])
        min2 = binsearch(a[mid:len(a)])
        if min1 < min2:
            return min1
        else:
            return min2

What is the time complexity for the function? include derivative steps to your answer

1. A block of mass m₁ = 2kg is placed on a 30 degree incline. The block is attached to a string that passes over a pulley at the top of the incline. vertically from a string that passes over a pulley. A mass m₂ = 0.2kg is hanging from the other end of the string. If the coefficients of static and kinetic friction are u_s = 0.4 and u_k = 0.3,
   1. Will the system accelerate if it’s initially at rest? Justify your answer with physics!
   2. If it does accelerate, what is the acceleration? In which direction is this acceleration?
   3. What is the value of m₂ that will cause the system to be stationary if friction is negligble?

Can you find any proofs or explanations that hash algorithms (such as MD5 and SHA1) are as good as they appear to be?

In the US, UK and various European countries, nationalists have been railing against free trade and in particular economic integration. What are the economic and political arguments for regional economic integration?

It is difficult to make a budget that spans several years, because prices are not stable. If your company needs 200 pencils per year, you cannot simply use this year’s price as the cost of pencils two years from now. Because of inflation, the cost is likely to be higher than it is today.

The program asks for the cost of the item, the number of years from now that the item will be purchased, and the rate of inflation. The program then outputs the estimated cost of the item after the specified period. Have the user enter the inflation rate as a percentage, such as 5.6 (percent). Your program should then convert the percent to a fraction, such as 0.056, and should use a loop to estimate the price adjusted for inflation.

Are states still the most important actors in international Relations? Why or Why not?

The United States instituted tariffs (increase in price of Chinese goods imported into the US) on China selectively on 7/6/18 of 10% on ultimately $50billion of goods.

China retaliated in kind by imposing tariffs (increase in the price of US goods imported into China) on US on the same day by the same amount

On 5/15/19, The US increased the amount of the tariff to 25% and expanded the list of Chinese goods covered by the tariff.

Chinese responded in kind by the amount of the tariff and the list of goods covered.  

Using the production possibilities model, and making the assumptions that the US and China are the only countries in the world, and making the assumption of constant costs in production, and assume also that the 2 countries produce only 2 goods: Soybeans and Consumer goods, with the US having a comparative advantage in Soybeans, China having a comparative advantage in Consumer Goods, explain what you would expect to happen once these tariffs are imposed.  

Please include in your discussion, what effect, if any, these tariffs (trade war) would have on the costs of production, level of production, level of consumption in each country.

Finally, relax the assumption about US and China being the only two countries in the world. If other countries are allowed to trade with either China or the US, what would happen to the level of production and price of each good? Be sure to note all the assumptions you are making in your analysis. Your answers need not be lengthy, if you would like to include graphs that is ok.

The Federal Reserve is responsible for managing the country’s money supply. Monetary policy affects the whole economy through interest rates. When the Fed increases the money supply, interest rates drop. When the Fed decreases the money supply, interest rates increase. This week you will discuss how you are affected by the Federal Reserve’s monetary policies. In your discussion, please consider the following questions or statements. Think about a recent purchase you made that required a loan, like a house, or a new car. Explain how you arrived at the decision to purchase. Then explain how the interest rate on the loan affected your purchase. For instance, were you able to purchase a higher priced item because the interest rate was low? Thinking deeper about your answers; how do interest rates affect millions of other buyers and their decisions, then how that affects the whole economy? Explain.

Explain the risks associated with leveling resources, compressing or crashing projects, and imposed durations or “catch-up” as the project is being implemented. Why is it critical to develop a time-phased baseline?

The cost was $500,000, to be paid in 30 days. When the cars arrived, some were in better condition than others. You sold 25 right away, for $10,000 each. Just to be safe, you sent the payments directly to Honda, even thought the whole sum was not yet due.

The remaining cars were a hard sell but you sold an additional 25 cars for $7500 each, and at the end of the month, you were left with 50 cars and the payment to Honda was due, as well as your rent, salaries, overhead etc.

In desperation, you sell the remaining 50 cars to another lot at a price of $4000 each. The price discount was based upon the purchaser's agreement to pay in cash upon delivery. When the driver returns after delivering the cars, instead of cash he hands you a check from the other dealer.......!

1. If the check clears, how much did you profit or lose in the transaction?

2. What action would you take now if the purchaser of the cars refused to pay with cash or a certified check, the regular check is the only payment available. What risks have you taken and what can the ramifications be?

3. What happens if the check does not clear (bounces)? What are your remedies? What will you do about your debt due to Honda?
