Gaseous calcium atoms absorb light at 423, 272, and 240 nm. After a photon of 272 nm is absorbed from the ground state, a photon of wavelength 672 nm is emitted. After absorption of a photon of 240 nm occurs from the ground state, a photon is emitted of wavelength 504 nm.

1. After the 504 nm photoemission occurs, what wavelength of light (in nm) would have to be emitted for an electron to return to the ground state? Construct an energy diagram to help.

2. What is the energy difference between the second highest and third highest states? Construct an energy diagram to help.

Select at least 4 or 5 of the highest revenue-producing products your firm currently offers to the marketplace or 4 or 5 of the highest revenue-producing companies that it currently operates, and then construct a BCG Matrix using relative market share and market growth rate as your two variables of interest. Identify each of the products (or companies) in your matrix as either a star, question mark (problem child), cash cow, or dog. Finally, for each product (or company) in the matrix, offer your opinion as to the likelihood that it will still be located in the same quadrant five years from now.

Compare the following two investment​ strategies: (1) invest for one year in the​ risk-free investment, and one year in the​ market, or​ (2) invest for both years in the market.

a. Which strategy has the highest expected final​ payoff? (Two possible outcomes)

b. Which strategy has the highest standard deviation for the final​ payoff?

c. Does holding stocks for a longer period decrease your​ risk?

Assume that the monthly profits of a company are given in an array, each entry representing
the profits for the corresponding month. Propose an algorithm to find a group of consecutive
months where the profit was the highest.
For example, the profits, in millions, for a year Jan-Dec is given by
A=[2 -5 3 4 0 -1 5 8 -9 1 -2 0];
The highest profit was from the period March-August and the value is 19 million. Assume
that the array can be very large{not just 12 months. Submit a well comment c++ pseudocode along
with an example of the algorithm

Solve for algorithms with complexity O(n)

In this project, you will be expanding on recent In-Class Activity to create a basic Scrabble Game. You do not need to worry about the game board, just the logic of the game. You may have up to 3 programmers in your group.

In this version of the game, players indicate how many rounds of play there will be for two players. Then each player will take turns entering words until the number of rounds are complete. In order for a word to be accepted, a letter in the word must correspond to a letter in a previous word. The exception is for the first word entered will be accepted without validating as there is nothing to validate against.

1. On the inputRounds() method, validate the number entered is numeric. If it is not, return a default numeric value of 2 instead.
2. On the inputWord() method, pass the player number and display in the input message.
3. On the inputWord() method, call a validation method called validWord(). This method will check to make sure the current word entered has a letter contained from the previous round with the exception of the first word entered.
4. On the validWord() method, the following validations need to take place:
   • Return False when word entered is empty
   • Return False when the word entered is the same as the previous word
   • Return True when nothing has been entered (ie this is the start of the game and as long as a word is not empty bypass validation)
   • Return False when the word entered must has no letters in common with the previous word entered
5. In the main program create the following Lists, Dictionaries, and Tuples
   • Create a Variables for player information using the names: rounds, player1, score1, player2, score2
   • Utilize the provided function that returns a Dictionary for the points per letter called points
   • Utilize the provided function that returns a List for end of game messages called messages
6. Optional unit testing available requires methods initMessages(), initPoints() to setup the initial values of the tuples, dictionaries and lists.

Values for messages List

Format Text Replacement will be used for the {} Text. See https://pyformat.info/ for more information on how to use the format() method.

• Player {} Wins with a score of {}!
• Tie Game, no winners.
• Invalid word! Player {} Wins!
• Invalid word! You must enter a valid word to start.
• Player {} Entered the Words:

Point Values Per Letter for points Dictionary

• 1 Point for Letters: a e i l n o r s t u
• 2 Points for Letters: d g
• 3 Points for Letters: b c m p
• 4 Points for Letters: f h v w y
• 5 Points for Letters: k
• 8 Points for Letters: j x
• 10 Points for Letters: q z

To use this call points['a'], where a is any lowercase letter you want to find the point value for.

Data Types for Variables

• rounds:
• currPlayer:
• prevPlayer:
• player1:
• score1:
• player2:
• score2:

Rubric / Grading Scale

• Appropriate Output of Instructions for user input for the number of rounds and words (6pt)
• 2 Functions utilized for initializing default values of points and messages (4pt)
• 4 Functions created as specified for inputRounds(), inputWord(), validWord(), playerScore() (12pt)
• 3 Unit Test cases found on test_main.py pass with OK (9pt)
• Working Scrabble Game per the above rules (19pt)

Total Points: 50

Additional Grading Notes

• Programmers must have attention to detail, as a result up to 2 Points may be taken for not updating the student info (Name, CRN, Semester Year) in the Markdown and Python Comments.
• Customers will not pay for programs that do not work, as a result up to 50 Points may be taken for programs that do not run due to syntax errors.
• Programmers tend to forget how large programs work over time, as a result up to 4 Points may be taken for programs that do not have a reasonable amount of comments that describe key sections of code.
• Minimum of 4 or more commits made to GitHub showing incremental programming changes towards the final program (4pt)
  • 1 Commit may be for updating Student Info in the Markdown and Python File
  • 3 Commits must be for programming updates to source code
  • If a unit test is available, no changes made to the Unit Test will count towards the required commits (nor should there be any changes made to this file).
  • This is a team project, all group members must have at least one commit with code changes. Updating student info does not count.
• All programs must have your Github URL submitted in Canvas via the assignment page. Unsubmitted Github repos will receive 0 Points.
• Programs that have been submitted and received a grade will not be regraded, unless the instructor makes a request for changes.
• If a program is eligible for regrading, it is the responsibility of the student to inform the instructor when the program is ready for regrading.

Happy Saturday. I'm working on my accounting homework ch. 11 and would liek to know if nayone coould possibly help out with this question...

Novak Company acquired a plant asset at the beginning of Year 1. The asset has an estimated service life of 5 years. An employee has prepared depreciation schedules for this asset using three different methods to compare the results of using one method with the results of using other methods. You are to assume that the following schedules have been correctly prepared for this asset using (1) the straight-line method, (2) the sum-of-the-years'-digits method, and (3) the double-declining-balance method.

What is the cost of the asset being depreciated?

What amount, if any, was used in the depreciation calculations for the salvage value for this asset?

Which method will produce the highest charge to income in Year 1?

1. Which subject had the highest rankings for relative peak power? Which subject had the lowest ranking? Provide an explanation as to why these individuals were the highest and lowest ranking?

2. Which subject had the highest rankings for relative mean power? Which subject had the lowest ranking? Provide an explanation as to why these individuals were the highest and lowest ranking?
