Organizational Behaviour

1. Equity theory is a model of motivation that explains how people strive for fairness and justice in social exchanges. In a short essay explain how feeling of inequity creates motivation to create equity (to reduce inequity).                                          

A mass m = 12 kg rests on a frictionless table and accelerated by a spring with spring constant k = 5249 N/m. The floor is frictionless except for a rough patch. For this rough path, the coefficient of friction is μ_k = 0.49. The mass leaves the spring at a speed v = 3.2 m/s.

A)How much work is done by the spring as it accelerates the mass?
B)How far was the spring stretched from its unstreched length?
C)

The mass is measured to leave the rough spot with a final speed v_f = 1.9 m/s.

How much work is done by friction as the mass crosses the rough spot?
D)What is the length of the rough spot?
E)In a new scenario, the block only makes it (exactly) half-way through the rough spot. How far was the spring compressed from its unstretched length?
F)In this new scenario, what would the coefficient of friction of the rough patch need to be changed to in order for the block to just barely make it through the rough patch?

a 2kg mass lying at rest at the origin is subjected to a force of 10 N directed along the positive X-axis and another force of 10 N along the positive y-axis. How far from the origin will the mass be in 5 seconds?

Let Y be a random variable that represents the number of infants in a group of 4,000 who die from asthma in a year. In the United States, the probability that a child dies from an acute asthma attack in a year is 0.0035.

a. What is the mean number of infants who would die in a group of this size?

b. What is the probability that at most four infants out of 4,000 die from asthma in a year?

c. What is the probability that between 6 and 10 infants out of 4,000 die from asthma in a year?

You have been called to testify as an expert witness in a trial involving a head-on collision. Car A weighs 1515 lb and was traveling eastward. Car B weighs 1125 lb and was traveling westward at 41.0 mph. The cars locked bumpers and slid eastward with their wheels locked for 21.5 ft before stopping. You have measured the coefficient of kinetic friction between the tires and the pavement to be 0.750. How fast (in miles per hour) was car A traveling just before the collision? (This problem uses English units because they would be used in a U.S. legal proceeding.)

After watching the Ted talk by Nadine Burke Harris, Identify two adverse childhood experiences, how they negatively impact mental health and wellness, and two ways to cope with the type of stress/trauma as one grows into adulthood.

The city of Mersey is planning to construct a bridge across the Cavendashim river. The first cost of the bridge will be $6611100. Annual maintenance and repairs will be $26233 for the first 5 years, and then will increase to $42927 for each of the next 10 years. For the final 5 years, the annual maintenance and repairs will increase again to $51791 per year. A major overhaul of $471158 will be performed at the end of year 9. Using an interest rate of 6%, what is the equivalent uniform annual cost for the 20-year period?

Hint: Since this is an equivalent uniform annual cost, do you need to indicate that as negative? See example 6-3 and 6-4 in the book.

Enter your answer as 1234

Round your answer. Do not use a dollar sign ("$"), any commas (","), or a decimal point (".").

Consider an electrochemical cell involving the overall reaction

2 AgBr(s) + Pb(s) → Pb2+(aq) + 2 Ag(s) + 2 Br–(aq)

Each half-reaction is carried out in a separate compartment. The anion included in the lead half-cell is NO3–. The cation in the silver half-cell is K+. The two half-cells are connected by a KNO3 salt bridge. If [Pb2+] = 1.0 M and [Br-] = 0.14 M, what is the emf of the cell at 298 K?
Given:

AgBr(s) + e– → Ag(s) + Br–(aq)              E° = +0.07 V.

Pb⁺² + 2e– → Pb(s)                                E° = - 0.13 V.

Which of the following statements about information technology is NOT true? a. It has resulted in leaner organizations. b. It has increased collaboration among employees. c. It has improved management processes. d. It provides more flexible operations. e. It has provided more down time for employees.

What_advantages _do_ finance_ companies_ have over commercial banks in offering services to small business customers? What are the major subcategories of business loans? Which category is largest?

A mountain climber jumps a 3.2m -wide crevasse by leaping horizontally with a speed of 7.1m/s . If the climber's direction of motion on landing is -45?, what is the height difference between the two sides of the crevasse?

Suppose you own an outdoor recreation company and you want to purchase all-terrain vehicles (ATVs) for your summer business and snowmobiles for your winter business. Your budget for new vehicles this year is $240,000. ATVs cost $8000 each and snowmobiles cost $12,000 each.

a.Draw a budget line for your purchase of new vehicles.

b. What is the opportunity cost of one ATV?

c. What is the opportunity cost of one snowmobile?

Beck Inc. and Bryant Inc. have the following operating data:

a. Compute the operating leverage for Beck Inc. and Bryant Inc. If required, round to one decimal place.

b. How much would income from operations increase for each company if the sales of each increased by 15%? If required, round answers to nearest whole number.

c. The difference in the   of income from operations is due to the difference in the operating leverages. Beck Inc.'s   operating leverage means that its fixed costs are a   percentage of contribution margin than are Bryant Inc.'s.

2. What is the consequence of using unconditional logistic regression to analyze the data collected from a 1:M matched case-control study?

Python program problem:

A group of statisticians at a local college has asked you to create a set of functions that compute the median and mode of a set of numbers. Define these functions, median and mode, in a module named stats.py. Also include a function named mean, which computes the average of a set of numbers. Each function should expect a list of numbers as an argument and return a single number. Each function should return 0 if the list is empty. Include a main function that tests the three statistical functions using the following list defined in main: userList = [3, 1, 7, 1, 4, 10] An example of the program output is shown below: List: [3, 1, 7, 1, 4, 10] Mode: 1 Median: 3.5 Mean: 4.33
