particles undergoing diffusion move a few millimeters per hour. In reality, particles are traveling around 500 m/s. The slow overall movement is because they collide with other particles very frequently. (density of water =1000 kg/m^3, Avogadro's # = 6.022x10^23 particles/mole, mass of the earth =5.97 x10^24 kg) using Xrms = sqrt(2Dt)

a. Estimate how far a water molecule travels before colliding with another water molecule.

b. How much time is in between each collision?

c. How many collisions occur for a molecule that diffuses 1 mm in 1 hour? d. Use your estimates from a, b, and c to figure out how many times a water molecule moves away from its starting point and how many times it moves towards it to end up 1 mm away after 1 hour.

Exercise 6-12 The Flint Inc., a manufacturer of low-sugar, low-sodium, low-cholesterol TV dinners, would like to increase its market share in the Sunbelt. In order to do so, Flint has decided to locate a new factory in the Panama City area. Flint will either buy or lease a site depending upon which is more advantageous. The site location committee has narrowed down the available sites to the following three very similar buildings that will meet their needs.

Building A: Purchase for a cash price of $618,900, useful life 27 years.

Building B: Lease for 27 years with annual lease payments of $71,820 being made at the beginning of the year.

Building C: Purchase for $652,700 cash. This building is larger than needed; however, the excess space can be sublet for 27 years at a net annual rental of $6,430. Rental payments will be received at the end of each year. The Flint Inc. has no aversion to being a landlord.

In which building would you recommend that The Flint Inc. locate, assuming a 12% cost of funds? (Round factor values to 5 decimal places, e.g. 1.25124 and final answer to 0 decimal places, e.g. 458,581.)

Net Present Value

Building A: $

Building B: $

Building C: $

The Flint Inc. should locate itself in:

Why is it important to prepare a financial budget?

Explain what is meant by the term "time value of money". For example, why might it be better to receive $8 today, over receiving a promise of $9 seven years from now?

How should one consider the time value of money when planning for retirement? Please share examples within your response.

Ron supervises three operations at ACME Company – filling, packing, and labeling. He was promoted from within the organization. Last week, Ron informed his operations manager Dan that he was resigning for a better-paying job and one that is closer to his residence. Ron gave Dan a month’s notice and offered to onboard the new supervisor. Each operation is staffed with a crew of lowly-skilled employees but with long tenure and decent pay. Over the course of their employment, they have formed a bond and an informal leader has surfaced from each crew. Ron is facing several operational issues. Employee motivation has been diminished. Morale is low, and absenteeism is at 10%. Overtime rate has risen to 20%. Employees perceive obvious favoritism and unfair labor practices. The productivity numbers are way below standard, and product returns have risen. Each crew seems to work as an island, and intergroup conflict is brewing. Communication is hampered by conflict, indifference, and alienation. Among the groups, Ron has identified two new college graduates as his potential successor; however, the groups especially the informal leaders have not accepted them completely. Therefore, neither can expect a warm welcome from employees who may be passed over for the promotion. Dan is thinking of recruiting outside candidates for the position. This person must be fit for the job and quickly address the issues facing the operations. You are tasked to hire and select the best candidate for the job. Apply all the organizational behavior theories and concepts you have learned over the past few weeks.

Research and present the following requirements: Job description – List all the job information, qualifications, and responsibilities suitable for this position. Recruitment plan – Design how to draw the best applicants for this job including advertising, job posting, and any incentives. Selection process – Use an effective method for narrowing down the list for and selecting the best applicant. Interview Questionnaire – Prepare a list of questions that will be asked during the interview process.

Meiosisis the process in which a diploid cell that contains two copies of the genetic material produces an haploid cell with only one copy (sperms and eggs). The resulting molecule of genetic material is linear molecule that is composed of consecutive segments: a segment that originated from one of the two copies followed by a segment from the other copy and vice versa. The border points between segments are called points of crossover. The Haldane model for crossovers states that the number of crossovers between two loci on the genome has a Poisson(λ) distribution. Assume that the expected number of crossovers between two loci in a fixed period of time is 2.25.The next 3 questions refer to this model for crossovers. (The answer may be rounded up to 3 decimal places of the actual value.)

1. The probability of obtaining exactly 4 crossovers between the two loci is

2. The probability of obtaining at least 4 crossovers between the two loci is

3. A recombination between two loci occurs if the number of crossovers is odd. The probability of recombination between the two loci is, approximately, equal to ??? (Compute the probability of recombination approximately using the function "dpois". Ignore odd values larger than 9)

2. Price-discriminating firms charge higher prices to those who

• have greater incomes.

• have higher price elasticities of demand compared to others.

• have more inelastic demand.

• have many substitutes available to them.

• 3. Two customers, Fred and Lamont, walk into a Grady’s Used Pickups. Who probably has a more inelastic demand for one of Grady’s pickups: people like Lamont, who are good at shopping around, or people like Fred, who know what they like and just buy it?

• People like Fred

• People like Lamont

• 4. Where will you see more price discrimination: In monopoly-type markets with just a few firms or in competitive markets with many firms?

• Competitive markets

• Monopoly-type markets

• 5. Consider two groups of people who shop at the same Wal-Mart: the Convenience Shoppers and the Bargain Shoppers. Which of the following statements is most likely to be true?

• Wal-Mart is more likely to have monopoly power over Bargain Shoppers because this group is more likely to splurge on something on a whim rather than stick to their prearranged shopping list.

• Wal-Mart is more likely to have monopoly power over Bargain Shoppers because this group is more likely to stick to their prearranged shopping list rather than splurging on something on a whim.

• Wal-Mart is more likely to have monopoly power over Convenience Shoppers because this group is more likely to stick to their prearranged shopping list rather than splurging on something on a whim.

• Wal-Mart is more likely to have monopoly power over Convenience Shoppers because this group is more likely to splurge on something on a whim rather than stick to their prearranged shopping list.

• 6. When will a monopoly create more output: When the government bans price discrimination or when the monopoly is allowed to and can perfectly price discriminate?

• Monopoly-type markets

• Competitive markets

A forklift will last for only 4 more years. It costs $6,100 a year to maintain. For $16,000 you can buy a new lift that can last for 9 years and should require maintenance costs of only $3,100 a year. a-1. Calculate the equivalent cost of owning and operating the forklift if the discount rate is 6% per year. (Do not round intermediate calculations. Round your answer to 2 decimal places.) a-2. Should you replace the forklift? b-1. Calculate the equivalent cost of owning and operating the forklift if the discount rate is 14% per year. (Do not round intermediate calculations. Round your answer to 2 decimal places.) b-2. Should you replace the forklift?

Python:

def factors(matrix, factor):

The matrix is a 3D list of integers.

factors are either one, two, or three

If the factor is 'one' it will return a the first value from each list

if the factor is 'two' it will return the second value, and same for the third.

Example;

input = [ [ [1, 2, 3], [3, 2, 9], [9, 8, 6] ],

[ [0, 0, 4], [8, 9, 0], [5, 2, 1] ],

[ [0, 1, 1], [5, 5, 9], [3, 8, 4] ] ], 'one')

output = [ [1, 3, 9], [0, 8, 5], [0, 5, 3] ]
