8. Refer to the previous problem. The parent particle moves in the lab with kinetic energy 800 MeV, and one daughter particle is emitted along the parent’s direction of motion. Find the lab kinetic energy (in MeV) for the daughter emitted backwards in the parent’s rest frame.

Previous Problem: 7. A particle of rest energy 800 MeV decays in its rest frame into two identical particles of rest energy 250 MeV. What are the kinetic energies (in MeV), momenta (in MeV/c), and velocities (in units of c) of the daughter particles?

A firm is considering replacing the existing industrial air conditioning unit. They will pick one of two units. The first, the AC360, costs $26,774.00 to install, $5,198.00 to operate per year for 7 years at which time it will be sold for $6,919.00. The second, RayCool 8, costs $41,604.00 to install, $2,063.00 to operate per year for 5 years at which time it will be sold for $9,086.00. The firm’s cost of capital is 5.80%. What is the equivalent annual cost of the RayCool8? Assume that there are no taxes.

ROUND TO 2 DECIMAL PLACES. THANK YOU IN ADVANCE.

This week we will discuss the topic of energy balance. The CDC reports that obesity has reached epidemic levels and that we have basically lost the war on obesity. Something is wrong in our approach to healthy living, and we see that people can lose weight on diets but almost all regain the lost weight within 2-5 years. As a society, dieting is not working. There is a "counter-culture" movement that is gaining traction called HAES - Health At Every Size. Explore this new way of thinking about health as more than just a number on a scale.

Please respond to the following: What did you learn about HAES, and what do you think of the approach? Include in your post at least two positives to the concept and two concerns that you have on the concept?

This requires you to conduct a one-way analysis of variance.

Data are given to you on the “days on market” for a random sample of homes for sale by realtors using 5 different training programs that the realtors experienced. The 5 programs can be described as: computer-based course, campus training (on-site in a classroom), apprentice (work side-by-side with a mentor), field (solo field training), and self (a self-paced training course with books and coursework at home).

1. Present the null and alternative hypothesis for an experiment to determine if there are significant differences in the “days on market” for the realtors experiencing the different training programs.

2. Present the excel output for the one-way analysis of variance and state your decision (whether you reject or fail to reject the null) and conclusion (whether you have sufficient evidence for, or insufficient evidence for,….the alternative). Be sure to clearly state your F_computed (a.k.a. F-value) and P-value.

A researcher is interested in studying the effect that the amount of fat in the diet and amount of exercise has on the mental acuity of middle-aged women. The researcher used three different treatment levels for the diet and two levels for the exercise. The results of the acuity test for the subjects in the different treatment levels are shown below.

a) Perform a two-way analysis of variance and explain the results. (Show all work)

b) Find the effect size for each factor and the interaction and explain the results. (Show all work)

Write a program that calculates the floor of a decimal number as defined here. Basically the Floor of any decimal number x, is the nearest whole number less than or

equal to x. ( Code Should Be In C++)

Requirements

1) You must implement a function to calculate the floor (you cannot use C++'s floor function). Name it floorAndError). It will have a return value and a single parameter

2) The program will ask the user to input a number (let's call this variable userInput) in main

3) The number will be passed to floorAndError by Reference and no other variables should be passed in

4) The function should change the userInput variable to the nearest whole number less than or equal to the original value of userInput that was inputted by the user. Therefore if the user inputted 4.3 into the variable userInput, after the function runs userInput will have the value 4.0. (note if the user enters -4.3 the floor is actually -5, think about how you might do this)

5) The function should return how much the value was changed by, i.e., the difference the new value of userInput and the old value of userInput. SO if the user inputted 4.3 the function will return a value equal to 4.0-4.3= -.3

6) The program should define the function prototype above main and the function definition after main

7) All the program input and output should occur in main

8) The function comments must have a pre condition and post condition both at the function prototype and the function definition

9) All the rest of the code should include comments too

In the last 40 years, the concentration of carbon dioxide in the air has increased by more than 20%. IR spectroscopy shows that carbon dioxide absorbs IR radiation.

If carbon dioxide molecules absorb IR radiation, where does that energy go? How does the increase in the concentration of carbon dioxide affect the air temperature?

If carbon dioxide molecules absorb IR radiation, the energy goes into( ___). Vibrating carbon dioxide molecules make other molecules in the air move faster. This means that the average (___)energy of the air molecules(___)and therefore the air temperature(___). Since the concentration of carbon dioxide has increased in the last 40 years, ( ___)IR radian is now absorbed leading to(___)temperatures.

Answer bank: higher, lower, potential, kinetic, increases, decreases, less, more, bond breaking, rotational motion, vibrational motion

You have just arrived at a SnappyPrints Inc., a maker of photo printers.  You are working in the Financial Planning department and have joined a team conducting capital budgeting analysis. Snappy is considering two new projects. Project Mini Printer (PMP) and Project High Speed Printer (HSP).  The WACC is 10%.

You will need to decide which project should be chosen.  Use Ch11 text and slides as a guide.

                                   0                      1                      2                      3

                                   |                      |                      |                      |

Project PMP ($    -150                   40                   75                   100

Project PHS ($)   -150                   65                   75                    85

Answer the following questions:

1.     What is capital budgeting?  Are there any similarities between a firm’s capital budgeting decisions and an individual’s investment decisions?

2.     What is the difference between independent and mutually exclusive projects?  Between projects with normal and non-normal cash flows?

3.     Define the term NPV. What is each project’s NPV? According to NPV, which project(s) should be accepted if they are independent? Mutually exclusive.

4.     How would the NPV’s change if the cost of capital changed?

5.     Define the term IRR. What is the IRR of each project?

6.     What is the logic behind the IRR method?  According to IRR, which project(s) should be accepted if they are independent?  Mutually exclusive?

7.     Calculate and draw NPV profiles for Projects L and S. (Use slides as a guide) Do the NPV profiles cross? If so, what is the crossover rate?

8.     Look at your NPV profile graph without referring to the actual NPVs and IRRs.  Which project(s) should be accepted if they are independent?  Mutually exclusive?  Explain.

9.     What is the underlying cause of ranking conflicts between NPV and IRR?

10.  What is the reinvestment rate assumption, and how does it affect the NPV versus IRR conflict?

11.  Which method is the best?  Why?

12.  Define the term modified IRR (MIRR).  What is the MIRR for each project?

13.  What are the MIRR’s advantages and disadvantages as compared to the NPV?

14.  What is the payback period?  Find the discounted and regular paybacks for the Projects.

15.  What is the difference between the regular and discounted payback methods?

16.  What are the two main disadvantages of discounted payback?  Is the payback method useful in capital budgeting decisions?  Explain.

Upon further analysis, SnappyPrints believes that sales of the new High-Speed Printer would cannibalize the sales of its existing I-Phone Rapid Print Accessory by 50%, resulting in lost annual cash flow of $25.  

17. How can we define/what do we call this effect?
18. Should this effect be included in the cash flow projections?   
19. If so, which project should be accepted?
