Two infinitely long parallel rods carrying uniform charge density lambda are at a distance d from each other. Find the electric force on a particle of charge q_* located a distance d directly left of one of the rods. (Derive the formula using Gauss' Law)

334423. #1: Write a program that optionally accepts an address and a port from the command line. If there is no address/port on the command line, it should create a TCP socket and print the address (i.e. server mode). If there is an address/port, it should connect to it (i.e. client mode). Once the connections are set up, each side should enter a loop of receive, print what it received, then send a message. The message should be “ping” from the client and “pong” from the server.

Hints:

You will need to pick a port for the server – something over 1024.

Ensure that you open your firewall to let the signal through.

1. In some collisions, KE is less after the collision than before. Since energy

cannot be lost, what happened to it? What could you do to show this is true?

2. A 2.00g bullet strikes a 2.00kg block hanging from a long cord. The bullet imbeds itself in the block causing the block with bullet embedded to swing upwards to a height of 50.0 cm above its original position.

A. What type of collision best describes the bullet striking the block?

B. Do a walk-through of the energy of the system starting just before the bullet strikes the block and continue until the block and bullet reach max height.

C. Find the velocity of the bullet before it collides with the block.

3. A 450g rubber ball is dropped from 2.0m above the floor. After the bounce, the ball only rises to a height of 1.5m above the floor.

A. Determine the change in momentum of the ball when it hits the floor and bounces up. (hint: either use motion equations or conservation of energy to determine the speed of the ball when it reaches the floor.)

B. Calculate the amount of heat generated when the ball hits the floor.

C. Explain how momentum is conserved when the ball collides with the floor.

Is it true that for any production function diminishing marginal return to each factor implies decreasing returns to scale? (with proof using the general production function, if possible)

3. A pharmacy is using X bar and R charts to record the time it takes to fill a prescription after the customer has turned in or called in the prescription. Each day, the pharmacy records the times it takes to fill six prescriptions. During a 30-day period, the hospital obtained the following values: X double bar = 20 minutes; R bar = 4 minutes. The upper and lower specifications are 23 minutes and 13 minutes respectively. What is the value of Cpk, to two decimal places?

Gold Mining, Inc. is using the profitability index (PI) when evaluating projects. Gold Mining’s cost of capital is 5.40 percent. What is the PI of a project if the initial costs are $1,449,850 and the project life is estimated as 10 years? The project will produce the same after-tax cash inflows of $634,623 per year at the end of the year.

Round the answer to two decimal places.

Two capacitors C₁ = 3.2 ?F, C₂ = 13.5 ?F are charged individually to V₁ = 19.0 V, V₂ = 5.6 V. The two capacitors are then connected together in parallel with the positive plates together and the negative plates together.

1.Calculate the final potential difference across the plates of the capacitors once they are connected.

2.Calculate the amount of charge (absolute value) that flows from one capacitor to the other when the capacitors are connected together.

3.By how much (absolute value) is the total stored energy reduced when the two capacitors are connected?

The energy released in the most energetic hydrogen bombs is often expressed in terms of how much TNT it would take to create the same energy release. The energy content of a large H-bomb is often expressed in megatons (1 megaton = 1 million tons of TNT). In more commonly used units, a megaton corresponds to 4.2 x 1015 Joules of energy, where a Joule is the kinetic energy of a softly hit tennis ball.

Given that information, calculate how much energy was released when the KT impactor hit the Earth 65 million years ago. Express your answer in terms of how many megaton H-bombs it would take to produce the same amount of energy. The energy released corresponds to all of the original kinetic energy of the incoming asteroid, which was moving at an estimated speed of 50 km/sec. Assume that the asteroid was spherical and had a diameter of 12 kilometers and a density of 3000 kg/m3.

Remember that the mass m of a body is its density times it volume. And use the fact that the kinetic energy of a body moving at velocity v is ½mv2. (Youll have the answer in Joules if you use kilograms for mass and meters/sec for the velocity.)

Python question

Your code can make use of any of the BinarySearchTree ADT methods: BinarySearchTree(), insert_left(), insert_right(), get_left(), get_right(), set_left(), set_right(),get_data(), set_data(), search(), __contains__ and insert().

Define a function called create_bst_from_list(values) which takes a list of values as a parameter. The function should create a binary search tree by using the insert() method.

Note: You can assume that the BinarySearchTree class is given and the parameter list is not empty.

For example:

tree = create_bst_from_list([7, 12, 4, 9, 20])
print_tree(tree, 0)

7
(L)    4
(R)    12
(L)        9
(R)        20

tree = create_bst_from_list([8, 3, 1, 6, 4, 25, 78])
print_tree(tree, 0)

8
(L)    3
(L)        1
(R)        6
(L)            4
(R)    25

        self.__left = left
        self.__right = right
    def insert_left(self, new_data):
        if self.__left == None:

        else:
            tree = BinarySearchTree(new_data, left=self.__left)
            self.__left = tree
    def insert_right(self, new_data):
        if self.__right == None:
            self.__right = BinarySearchTree(new_data)
        else:
            tree = BinarySearchTree(new_data, right=self.__right)
            self.__right = tree
    def get_left(self):
        return self.__left
    def get_right(self):
        return self.__right
    def set_left(self, left):
        self.__left = left
    def set_right(self, right):
        self.__right = right
    def set_data(self, data):
        self.__data = data

Haley Company produces one product and has the capacity to make 150,000 units per month. The cost that is associated with producing 125,000 units is shown below:

The selling price per unit is $150. The Haley company was contacted by a prospective customer interested in purchasing 25,000 units for $100. The management team is considering this offer and in the meeting about this new prospect, you (the management accountant), stated that the fixed cost will remain the same, but the variable cost will increase along with $10 shipping expense due to the customer’s international location. Management has asked you to determine if they should accept or reject the new customer proposal and what nonmonetary factors should be considered.
