A spherical raindrop falling through mist builds up mass. The mass accumlates at a rate proportional to its cross-sectional area and invers;ey proportional to its velocity, that is, dm/dt=k?r2/v, where r is the radius of the raindrop at a given time and v is the downard speed at the same time.Assuming the density P of the rain drop is a constant. Ignoring the resistance do to the fog and the air, calculate the instaneous acceleration of the raindrop as a function of v,r,P,g and k.

Software testing occurs near the end of the programming process. Because of this, if a project falls behind schedule, testing time is often reduced. Discuss the possible impacts of less-than-thorough testing. Topics might include company reputation, customer dissatisfaction, the company’s ability to sell new or updated products, etc. Discuss which is worse: releasing a product late or releasing it on time without fully testing it. "please answer based on arguments"

| Input Quantity | Real GDP |
| 300.00 | $400 |
| 225.00 | 300 |
| 150.00 | 200 |
a. What is the level of productivity in this economy?
b. What is the per-unit cost of production if the price of each input unit is $4?
c. Assume that the input price increases from $4 to $5 with no accompanying change in productivity. What is the new per-unit cost of production?
c2. In what direction would the $1 increase in input price push the economy's aggregate supply curve? (right or left)
c3. What effect would this shift of aggregate supply have on the price level and the level of real output?
d. What would be the new per-unit cost of production?
d2. In what direction would this change in per-unit production cost push the economy's aggregate supply curve? (right or left)
d3. What effect would this shift of aggregate supply have on the price level and the level of real output?

1. Some students are more interested in the advertising component of marketing. Identify the factors that make a television commercial memorable. Identify five commercials. We often remember commercials that we don’t like as well as the ones that we do like. Who is the target market for each ad? Identify why the ad was memorable. What advertising appeal was used?
2. Evaluate and compare the super bowl ads for the last two years (2018 & 2019). What ads were deemed the best? Do you agree? Did you see any differences in the ads from the two years? Did you identify any trends? Identify at least three ads that illustrate this trend.

In previous weeks, we’ve talked a bit about the conceptual difference between the notion of a “residual” welfare state and an “institutional” welfare state. Explain what the difference is between these two models of the welfare state. What did the New Deal and its signature legislative achievements (think: the Social Security Act of 1935, the various work relief programs) represent in terms of how America’s approach to social welfare issues and policy was changing?
