1. What do you think are the main challenges and implications being faced regarding the changes in the service concept of KidZania, centered on experiential learning?

2. Considering the experience gained from all their current parks as well as the external forces including increasing competition, market regulations, diversity of potential new markets, and technology integration, what criteria should KidZania’s management follow in selecting specific activities for its future “cities” to enhance experiential learning while remaining profitable?

I have three different homework questions I cannot seem to get
My hw is due at 12 so if anyone can help that would be helpful

Thank you


1)   For a car moving with speed v, the force of air drag is proportional to v2. If the power output of the car's engine is quadrupled, by what factor does the speed of the car increase?



2)Tarzan

(m = 76 kg)
commutes to work swinging from vine to vine. He leaves the platform of his tree house and swings on the end of a vine of length
L = 8.0 m.
(a) If the platform is 1.5 m above the lowest point in the swing, what is the tension in the vine at the lowest point in the swing?
kN

(b) Tarzan again takes to his morning commute, but this time a monkey of mass
mM = 30 kg
hitches a ride by jumping onto Tarzan's back. If a vine can withstand a maximum tension of 1200 N, will it snap under the tension of the added passenger?
Yes No

If so, at what angle with respect to the vertical does the vine break? (If the vine does not break, enter NONE.)

3) A wheel of mass 13 kg is pulled up a step by a horizontal rope as depicted in the figure below. If the height of the step is equal to one-fifth the radius of the wheel,

h = 1/5 R


what minimum tension is needed on the rope to start the wheel moving up the step? Hint: The wheel will start to move just as the normal force on the very bottom of the wheel becomes zero.

import java.util.ArrayList;

/*
    Lab-08: BinarySearchTree Implementation

    Rules:
        1. Allow Tester to iterate through all nodes using the in-order traversal as the default.
            This means, in Tester the following code should work for an instance of this class
            called bst that is storing Student objects for the data:

                BinarySearchTree_Lab08<String> bst = new BinarySearchTree_Lab08<String>();
                bst.add("Man");       bst.add("Soda");   bst.add("Flag");
                bst.add("Home");   bst.add("Today");   bst.add("Jack");

                for(String s : bst)
                    System.out.println(s);

        2.   You can not use a size variable to keep track of the number of nodes

"You work for a digital marketing company that has been approached by a leading company (identify company and sector -Hospitality) in South Africa. The company wants to improve its social media and digital marketing strategy they are using, how the position and strategies limit their current capabilities, the options available to them. Identify key factors that would help that company to develop their strategy and write a report for their Board of Executives. Identify their current position and strategies and the main recommendations for an enhanced social and digital marketing strategy.”

Report: Guide framework to your report

A report differs from an essay in that the Executive Summary is the introduction and conclusion in one.

|-------- Why something was done and why it is important

|-------- Purpose of the report (problem solving, feasibility, etc.).

|-------- Main findings and important recommendations.

The introduction and conclusion mentioned in the discussion section below are equivalent to the first and last stages of the main body of the essay.

Discussion Identify problem, position, possibilities, proposal Introduction

|-------- Background to the problem in detail. Review of pertinent issues from the literature. Proof and

|-------- Analysis of target situation and development other related factors. How many of claims sections are needed to interpret the situation? Conclusion &

|-------- What does this mean in light of recommendations review, corporate &/or industry concerns, public reaction, etc. What needs to be done?

Appendices Information (charts, statistics, and diagrams) that are too long for including in the discussion. Useful to present, but not directly relevant to the argument. Avoid using more than 2 or 3 pages of appendices if possible (NOTE: they are no part of the word count).

In an essay, theory & research interprets and informs practice, whereas in a report, practice primarily reflects and informs theory

Suppose that the average waiting time for a patient at a physician's office is just over 29 minutes. In order to address the issue of long patient wait times, some physicians' offices are using wait-tracking systems to notify patients of expected wait times. Patients can adjust their arrival times based on this information and spend less time in waiting rooms. The following data show wait times (minutes) for a sample of patients at offices that do not have a wait-tracking system and wait times for a sample of patients at offices with a wait-tracking system.

(JAVA)

Create a program that creates a mini database of numbers that allows the user to: reset the database, print the database, add a number to the database, find the sum of the elements in the database, or quit.

In main, you will declare an array of 10 integers (this is a requirement). Then you will define the following methods: • printArray (int[ ] arr) – this takes in an array and prints it • initArray (int[ ] arr) – this initializes the array so that each cell is 0 • printSum (int[ ] arr) – this calculates the sum of the elements in the array and prints it • enterNum(int[ ] arr) – this asks the user for a slot number and value – putting the value into the array in the correct slot • printMenu (int[ ] arr) – prints the menu in the sample output (that’s it, nothing more)

In main, create an array of 10 integers and immediately call initArray( ). Then, continuously looping, print the menu and ask the user what they want to do – calling the appropriate methods based on the user’s choice. Note that every time you call a method, you must pass the array that was created in main. If it makes it easier, we used a do-while loop and a switch statement in main.

It should behave like the sample output below: (user input = bold)

Would you like to:

1) Enter a number

2) Print the array

3) Find the sum of the array

4) Reset the array

5) Quit

Which of the following is the sociocultural concept of race?

Question 30 options:

A group of people who share a specific combination of physical, genetically inherited characteristics that distinguish them from other groups

Racial groups do not share any physical features.

The perspective that characteristics, values, and behaviors that have been associated with groups of people who share different physical characteristics serve the social purpose of providing a way for outsiders to view another group and for members of a group to perceive themselves.

The concept that racial classifications do not have any real-world consequences for people.

In “Seeing More Than Black and White,” Martinez argues that the black/white model of race and racism is:

Question 31 options:

Not helpful because it prevents marginalized racial groups from joining together to combat racism

Helpful because it highlights the oppression of black people in the United States

Not helpful because it does not focus on racism perpetrated by white people

Helpful because it simplifies very complicated race relations

Based on the class lecture, it is important for an ally to:

Question 32 options:

All of the above

Advocate for marginalized groups on a personal and systemic level

Examine their personal values, biases, and assumptions associated with individuals with different identities.

Acknowledge mistakes that they may make
