Using a script (code) file, write the following functions: 1. Write the definition of a function that takes one number, that represents a temperature in Fahrenheit. The function prints the equivalent temperature in degrees Celsius. (1 point) 2. Write the definition of another function that takes two numbers, that represent speed in miles/hour and time in minutes. The function prints the distance traveled based on that speed and time. (1 points) 3. Write the definition of a function named main. It takes no input, hence empty parenthesis, and does the following: - starts by showing on 3 lines using one print statement (you'll need to use the escape character for the new line) the following: Enter 1 to convert Fahrenheit temperature to Celsius Enter to calculate distance travelled Enter 3 to exit - uses one input statement to get which number the user wants to input (1 or 2). Call this main_input. Make sure to make main_input an integer. - if main_input contains 1, get one input then call the function of step 1 and pass it the input. After this line, call main. - if main_input contains 2, get two more inputs and call the function of step 2 and pass it those two inputs; watch out for the order. After this line call main. - if main_input contains 3, then print a good bye message. Do not call main, as this will cause 'us' not to exit. - if main-input is none of the above, print an error message, then call main. After you complete the definition of the function main, write a statement to call main. (3 points) Below is an example of how the code should look like: #Sample Code by Student Name #Created on Some Date

(1 point) Find the set of solutions for the linear system $3x_1 - 6x_2 + 3x_3 = -7$ $4x_2 + 7x_3 = 8$ Use s1, s2, etc. for the free variables if necessary. $(x_1, x_2, x_3) = ( rac{5}{3} - rac{9}{2}s_3, 2 - rac{7}{4}s_3, s_3)$

2 Hamiltonian Spin-orbit in Hydrogen Atom The spin-orbit coupling Hamiltonian between an electron and a proton in a hydrogen atom is given by: $H_{so} = \frac{A}{r^3} \vec{S} \cdot \vec{L}$ a.) Explain the origin of $H_{so}$ (Especially, why do we call it a relativistic effect?) b.) What do $\vec{S}$ and $\vec{L}$ represent? c.) By introducing a combined angular momentum $\vec{J} = \vec{L} + \vec{S}$, calculate the energy eigen- values of $H_{so}$. you may use $\left< \frac{1}{r^3} \right> = \frac{1}{l(l+1/2)(l+1)n^3a_0^3}$ QM: Homework 5 where l is the angular momentum quantum number, n is the principal quantum number and $a_0$ is the Bohr Radius d.) Sketch an energy diagram of a Hydrogen atom for the n=2 level with and without the perturbing $H_{so}$. You should label each state using the term notation lj.

1. [5 pts] Suppose you have the following binary search tree Nodes and methods from the lecture notes on Binary Search Trees - unbalanced (with a couple get/set methods in italics that were not in the slides, but that you can figure out): class BST<Item> { BSTNode<Item> root; public BST<Item>(root){} public BSTNode<Item> getRoot() {} public void setRoot (BSTNode<Item> n){} } class BSTNode<Item> { Item value; BSTNode<Item> leftChild; BSTNode<Item> rightChild; BSTNode<Item> parent; public BSTNode<Item>(Item v, BSTnode left, BSTnode right, BSTNode parent) {} public BSTNode<Item> getLeft() {} public BSTNode<Item> getRight() {} public Item getData() {} public BSTNode<Item> search (Item target) {} public void add(Item element) {} public void add(BSTNode<Item> current, Item element) {} public Item getRightmostData() {} public Item getRightmostData(BSTNode<Item> current) {} public Item getLeftmostData() {} public Item getLeftmostData(BSTNode<Item> current) {} public boolean delete(Item target) {} } Suppose you have the following binary search tree Nodes and methods from the lecture notes on Binary Search Trees - unbalanced (with a couple get/set methods in italics that were not in the slides, but that you can figure out): Write a method to find and return the maximum value in the tree, and delete the node. Hint: Using the above methods, this is really short.
