In the Bohr model, when an electron leaves one n orbit and enters another n orbit, a photon is either emitted or absorbed. Derive a relationship between the wavelength of the emitted or absorbed photon and the change in the DeBroglie wavelength of the electron when it moves from one n to another n.

Programming Project #6: Bowling Team
need to use python
Problem
Expected Duration: 3-4 hours
Prerequisites: None
Knowing that you are a budding programmer, your friends have
asked you to create a scoring program for your Saturday bowling
league. Your program should take a name, team number, and score for
each player, and should deal with any number of players, but have 3
people to a team.
Your program should ignore invalid inputs, and not crash. Your
program should print the following lists in columns:
Last, your program should write each of the lists and the
summary information
to a text file called game_results.txt in the same format it is
displayed on the screen.
Note: You have the option of using pandas Dataframes in your
program. Just make sure the console and file output
has the required structure and format.

We can all agree that we never want to go through a bankruptcy.
However, it is in all of our best interests to truly understand the
bankruptcy law and process. For this assignment, I would like you
to read the following case and answer the questions presented. This
may require that you do some research on bankruptcy. Remember, any
sources you use must be cited and I do not want you to copy answers
from the internet. Think about the situation and apply your
knowledge, gained from your readings, to the questions. One to two
paragraphs for each question.
Jane Doe, a teacher, obtained a master’s degree at Somewhere University (names have been changed). But when Doe asked for a transcript—which was required to receive an increase in salary from her school district—the university refused because she owed more than $6,000 in tuition. Doe offered to pay the nominal transcript fee, but not the tuition. She then filed a petition in a federal bankruptcy court, listing the university as her only creditor, and while the case was pending, again asked for a transcript. The university again refused unless she paid the tuition. Doe complained to the court, which ordered the university to provide a transcript. A federal district court affirmed the order. The university appealed.
The U.S. Court of Appeals for the Seventh Circuit affirmed. Doe had
a right to a copy of her transcript, and the university’s refusal
to honor that right until she paid her tuition was an act to
collect a debt, in violation of the automatic stay. Property
interests are created and defined by the law. Nothing in the
Bankruptcy Code or other federal law creates or affects property
rights in grades or the right to a transcript. No state statute
applies either, but under the state’s common law, property rights
may arise from custom. In the state, universities have consistently
provided certified transcripts at or around cost. This indicates
that providing a transcript is an implied part of the “educational
contract,” covered by the tuition and other fees. Because a
transcript is part of the package of goods and services that a
college offers in exchange for tuition, a student has a property
right to a certified copy. In this case, Doe was willing to pay the
cost. The university’s only reason for refusing to provide the
transcript was to induce Doe to pay her unpaid tuition. But the
automatic stay prohibits a creditor from acting to collect a claim
against a debtor that arose before the filing of a bankruptcy
petition.

In a random sample of 19 residents of the state of Montana, the mean waste recycled per person per day was 1.4 pounds with a standard deviation of 0.7 pounds. Determine the 90% confidence interval for the mean waste recycled per person per day for the population of Montana. Assume the population is approximately normal. Step 1 of 2 : Find the critical value that should be used in constructing the confidence interval. Round your answer to three decimal places.

1. Design a class based on a modified Customer Structure. Use private and public definitions.
2. Create class methods (Setters and Getters) that load the data values. The Setter methods will validate the input data based on the criteria below and load the data into the class if valid.
For character arrays, the data must be within the specified data size. (See #3 below)
For zipCode, the number must be between 0 and 99999.
City and State need to be converted and stored in uppercase.
To get started loading the c-strings.
Getters
The book does not seem to provide a good example of what a (getter) method that returns a char array should look like. Section 9.9 is very close but uses string as examples instead of c-strings.
The best approach is to return a pointer to the c-string- Described as below:
char* getName(); // declaration - also known as prototype
// Customer is my Class name
char* Customer::getName() { // defined member function - Return a pointer to the c-string return name; }
cout << YOUR_INSTANCE_HERE.getName() << endl;
Setters
As for creating a setter method - you can define unsized char arrays in the method header
bool Customer::setName(char inputName[]) {
// code here..
}
3. Write a program that will allow me to enter data for the class and create and call a method that displays the data for the class.
During the input process, pass the input data to the setter method and confirm that the data entered is valid based on the class method return value. If not valid,prompt for me to re-enter the data until it does pass the class method's validation.(A do-while loop works well for this situation) I only need to enter the data for 1 instance of the class. The best way to do this is for the setter methods to return bool instead of void. If the data is valid, return true. Otherwise return false.
There is no need to loop for multiple instances of the object. Do not use cin statements inside the class method definitions.
Below is the original structure to use to create your class definition.
const int NAME_SIZE = 20;
const int STREET_SIZE = 30;
const int CITY_SIZE = 20;
const int STATE_CODE_SIZE = 3;
struct Customer { long customerNumber; char name[NAME_SIZE]; char streetAddress_1[STREET_SIZE]; char streetAddress_2[STREET_SIZE]; char city[CITY_SIZE]; char state[STATE_CODE_SIZE]; int zipCode;
};
Hints: The const variables need to be defined outside of the class definition.
All access to the data in the class must use public methods that you define. DO NOT DIRECTLY ACCESS the customer data items.
The class level input methods should return a boolean to confirm the data was loaded and passed any size or data ranges. The customerNumber setter does not need to return a value - It can be a void setter.
Set the customerNumber to 1 via the code - not user input. There is no input loop so only 1 set of customer's data is to be entered.

Write a python program to evaluate polynomials in general and test it on the following polynomial: ? 4 − 3? 3 − 39? 2 + 47? + 90 = 0
a) Develop and test a function named polyCalc() that evaluates a polynomial at a given value of the variable. The function receives two arguments: a list of the polynomial coefficients, and the value of the variable. It returns the result of the evaluation as a float. Use your function to evaluate the polynomial at ? = -5.4, -5.2, -1.2, -1.0, 2.0, 2.2, 7.2 and 7.4. What do you conclude about the solutions to the equation above?
b) Write a second function named polySolve() that seeks a solution of the polynomial between two values of the variable where the function has changed sign. This function should receive the list of coefficients, the two values of the variable between which there is a solution. It should return the value of the variable at which a solution was found. This function may be based on an exhaustive search, a bisection search, or on Newton-Raphson’s method. Select a method with some justification.

A company which produces a single product has definite orders for this product over the next four quarters as follows:
Quarter | 1 | 2 | 3 | 4 |
Demand | 460 | 600 | 340 | 500 |
The company ended the previous year with an inventory of 300 units, and the final quarter production level was 420 units. The company wishes to end this year with an inventory of at least 280 units.
It costs $30 per unit to increase the production level from one quarter to the next, and $56 per unit to decrease it. The cost of holding inventory from one quarter to the next is $40 per unit per quarter. No shortages are permitted. The company wishes to minimize the sum of production level change costs and inventory costs over the four quarter planning horizon.
Formulate (but do not solve) a model for this situation.
