A 5.87-g bullet is moving horizontally with a velocity of +348 m/s, where the sign + indicates that it is moving to the right (see part a of the drawing). The bullet is approaching two blocks resting on a horizontal frictionless surface. Air resistance is negligible. The bullet passes completely through the first block (an inelastic collision) and embeds itself in the second one, as indicated in part b. Note that both blocks are moving after the collision with the bullet. The mass of the first block is 1238 g, and its velocity is +0.631 m/s after the bullet passes through it. The mass of the second block is 1623 g. (a) What is the velocity of the second block after the bullet imbeds itself? (b) Find the ratio of the total kinetic energy after the collision to that before the collision.

1. David and Nate work for two different companies, but each performs the same job working on a loading dock. David, however, earns a higher salary than his friend Nate The difference in salary could illustrate union wages if David’s annual salary is covered by a collective bargaining agreement and Nate’s is not.
2. Critics argue that a disadvantage of the Earned Income Tax Credit is that it does not effectively target the working poor because many recipients are the teenage children of middle-income families.
3. Critics argue that a disadvantage of minimum-wage laws is that they do not effectively target the working poor because many minimum-wage workers are the teenage children of middle-income families.
4. One example of labor-market discrimination is that a firm may be less likely to interview a job candidate whose resume clearly indicates he is not a good fit for the job.

Researchers from the university of Kent, UK, were interested in whether collectivist or individualist attitudes are related to one’s intent to comply with social distancing and safety guidelines during COVID-19. Participants were classified as either collectivist or individualist, and rated their intent to comply with guidelines on a scale from 1-5, where 1 is definitely not and 5 is definitely yes. Please conduct an independent-groups t test to determine if there is a significant difference in intention to comply between individualists and collectivists.
In addition, please:
- report cohen’s d
- report r^2
- conduct and interpret an F-MAX test
- include 95% confidence intervals
- report your answer in words that directly address the research

Consider a firm as follows: Assume that the firm has no debt. The cash flows are received at the end of each year and are perpetual. Cost of equity capital for an unlevered firm, r0, is 20%. The first cash-flow will be received one year from today. All calculations for valuation are done today. Firm value is defined as collective value of debt and equity.
Sales = $ 500,000
Cash Costs = 360,000
Operating Income = 140,000
Tax @ 34% -47,600
Unlevered cash flow (UCF) $ 92,400
To illustrate that financing has no impact on firm value if
there are no taxes (i.e. financing affects firm value purely
because the interest payments generate tax-savings), and to further
illustrate the equivalence of various valuation methods.Assume the

the firm value using

Populism is a development that has exponentially been growing. Yet, globally there is much criticism of populist leaders. In preparation for this discussion, take a look at the concept of populism and Google it. Also, Google a couple of global leaders who are identified as populist.
Now, armed with that information, particularly in the midst of the critiques of democracy being taken away from the people by populist leaders, how do you think the concept of groupthink plays out in our society and how do you believe that trend towards groupthink can that trend be reversed?
Last, but not least, how do you believe groupthink will play into how the world navigates through this pandemic that is impacting people on a global basis? Can groupthink be a positive or a negative construct as we move through these times? How can groupthink contribute to the individual and collective stress of people?
This is just a general question from Organizational Development Perspective.
