Nuclear Energy Discussion

Scientists such as Heinrich Hertz, Philipp Lenard, Max Planck, and Albert Einstein made scientific contributions that ultimately demonstrated that light is electromagnetic radiation, and that it has a “dual nature.” Some electromagnetic phenomena are best explained with a particle model, and some with a wave model. In a sense, “wave” and “particle” are just easy mental models for light. We employ them because we are used to seeing waves and particles—such as those in water waves and baseballs—in our daily lives. Electromagnetic radiation is a basic concept in physics, but it doesn’t fit completely into one of these neat little boxes.

Research and discuss at least one modern technology that employs electromagnetic radiation and that can be explained by the wave model, the particle model, or a combination of the two. Some possible technologies include solar panels, burglar alarms, cameras, and cell phones.

Title: Physics Lab Guidelines

• Laboratory Preparation: Instructions to all lab experiments are posted on our Blackboard course website. Before performing each lab activity, students must read the instructions, prepare for the laboratory, and study the theory for the experiment. Online lab experiments will be performed by each student as specified in the lab instructions, and a single report will be submitted for each experiment activity. Students can work on the experiments individually or in small groups of 2 or 3 students, but each student must write and submit their own lab report and include a detailed list of contributions from all group members to the lab (see below).

• Laboratory Report Policy: Each lab experiment will span two weeks: The 1st week is devoted to reviewing the activity and collecting the data, while the 2nd week is devoted to completing the lab report. Each student will be responsible for producing a report pertaining to each experiment. Lab reports must be typed and submitted (uploaded as assignments) via Blackboard website using the corresponding link available in the Labs & Reports folder. Lab reports are due on Sunday by midnight (11:59 pm) before your next lab (see course schedule). Lab reports will be graded and returned to you via Blackboard website with feedback and comments. Reports will not be accepted via email. A student must pass the lab portion of the course in order to pass the entire course.

Title: Physics Lab Guidelines

• Late Report Policy: Late laboratory reports will only be accepted in the case of extreme emergency or illness and prior arrangements have been made with the instructor. Students that do not participate in the lab activity or do not submit the required lab report, will not get credit for the lab and will receive a grade of zero (0%). Refer to the course syllabus for more details.

• Format of Laboratory Reports: Laboratory reports must be typed professionally using Microsoft Word (*.doc or *.docx) and in standard font. Plagiarism and copying from the lab instructions or from another student will not be tolerated. Each report must be a single document less than 1 MB in size, and the basic parts of all lab reports must be arranged in the following order:

1. A “Title page” containing your name followed by your partner’s names if any, the title of the report, the

course code, section number, and the date when the experiment was performed.

Rainbow Physics & Criminal Justice

Power Point that explains the physics of a rainbow. What is a rainbow? What will affect if you see a rainbow or two? What do dispersion, refraction, and reflection have to do with rainbows?

Technical violations of parole, such as failing to inform a parole officer about a change in residence, contribute significantly to prison overcrowding. Evaluate the effectiveness of returning parolees to prison for technical violations. Should there be more leniency in handling these cases, or is strict enforcement necessary to maintain public safety and the integrity of the parole system? Discuss the benefits and problems associated with strict enforcement of technical violations, considering the potential impact on recidivism rates, prison overcrowding, and the successful reintegration of parolees into society. Be sure to include examples from the textbook in your answer.

PowerPoint Explanation — Physics of a Rainbow (general guidance)

Slide 1 — What is a rainbow?
A rainbow is a meteorological and optical phenomenon caused by sunlight interacting with water droplets in the atmosphere. When sunlight enters the droplet, it bends (refraction), separates into different wavelengths (dispersion), reflects off the inner surface of the droplet, and then refracts again as it exits. The result is a circular arc of colors typically seen opposite the sun. Primary rainbows show red on the outer edge and violet on the inner edge because each wavelength of light bends at a slightly different angle.

Slide 2 — Why you may see one or two rainbows
A single rainbow results from one internal reflection inside the water droplet. A double rainbow forms when the light reflects twice. The second reflection reverses the color order, so the secondary rainbow appears dimmer and shows red on the inner edge and violet on the outer. Whether you see one or two depends on the number of reflections, droplet size, and viewing geometry. Sun angle matters: rainbows are often visible when sunlight is low (morning or late afternoon).

  • Discuss the ethical legal and practical considerations that influence court rulings as well as the broader social and political context that shapes the debate over the death penalty.,

  • Be sure to include examples from the textbook in your answer.


Death Penalty Analysis — Three Paragraphs

One of the most persuasive arguments in favor of the death penalty is deterrence and retributive justice. Supporters argue that the most violent and irredeemable offenders—such as those who commit serial murders or extreme acts of brutality—should face the highest possible punishment. They claim that execution protects society by ensuring that such individuals never reoffend and may discourage others from committing similar crimes. Larry Siegel (2018) notes that corrections and punishment historically included incapacitation as a core goal; capital punishment represents the ultimate form of incapacitation as it permanently removes dangerous individuals from society. Proponents often frame the death penalty as a morally justified response to severe harm, delivering closure or symbolic justice for victims and their families.

The most compelling argument against the death penalty is the risk of wrongful conviction and disproportionate application. Opponents contend that once an innocent person is executed, the mistake is irreversible, making errors intolerable within a fair justice system. Siegel (2018) also emphasizes systemic inequities in corrections and sentencing, noting how punishment may be influenced by socioeconomic background, race, and access to legal representation. The death penalty often reflects these disparities, with marginalized groups more likely to receive capital punishment. Additionally, critics argue that the death penalty does not reliably deter crime and that life without parole can protect society while avoiding the moral harm of state-sanctioned killing.

Comprehensive Answers (general)

1) Introduction (theory — ~180 words)

This experiment explores the kinematics of free-falling bodies and the determination of gravitational acceleration (g) using measured distances and times. For an object released from rest and falling under uniform gravity (neglecting air resistance), the displacement ss after time tt follows the kinematic equation

s=ut+12at2s = ut + \tfrac{1}{2} a t^2

where uu is initial velocity (here u=0u=0), and aa is acceleration (for free-fall, a=ga = g). Thus s=12gt2s = \tfrac{1}{2} g t^2. Rearranging gives g=2s/t2g = 2s/t^{2}. An alternative analysis plots ss versus t2t^{2}: the slope of that linear plot equals 12g\tfrac{1}{2}g, so g=2×(slope)g = 2\times(\text{slope}). Important experimental considerations: measurement uncertainty in distance and time (±∆s, ±∆t), reaction time when using a stopwatch, and air drag which becomes important for low-mass or high-surface-area objects. Percent error is used to compare measured gexpg_\text{exp} with the accepted value gtheog_\text{theo} (standard near Earth’s surface ~9.806 m/s²):

% error=∣gexp−gtheogtheo∣×100%.\%\text{ error} = \left|\frac{g_\text{exp}-g_\text{theo}}{g_\text{theo}}\right| \times 100\%.

References (example): classical kinematics textbooks or lab manual. Define each term when used (s = displacement in m, t = time in s, g = acceleration due to gravity in m/s²).


2) Hypothesis (If / Then)

If identical-shape objects of different masses are dropped from the same height in the same environment, then they will hit the ground at (nearly) the same time because gravitational acceleration is independent of mass when air resistance is negligible.


3) Analysis (tables, chart/plot, percent error — textual + worked example)

Below is a complete, general analysis you can copy into your report. Replace the sample data with your measured data and attach images of your actual tables/plots where requested.

How to analyze & what to plot

  • Collect several trials for each drop height (e.g., 0.5 m, 1.0 m, 1.5 m). For each trial record measured time tt.

  • Compute average time tˉ\bar{t} and t2t^2 for each height.

  • Table distance ss (m) vs average t2t^2 (s²). Fit a straight line; slope = ½ g.

Sample Table 1 — raw data and averages (text)

Height ss (m) Trial 1 t (s) Trial 2 t (s) Trial 3 t (s) Average tˉ\bar{t} (s) tˉ2\bar{t}^2 (s²)
0.50 0.32 0.33 0.31 0.320 0.1024
1.00 0.45 0.46 0.44 0.450 0.2025
1.50 0.55 0.56 0.54 0.550 0.3025

Linear fit method
Perform linear regression of ss (y-axis) vs t2t^2 (x-axis). For these sample numbers, slope ≈ 4.90 m/s² (this is 12g \tfrac{1}{2}g ), so measured gexp=2×slope≈9.80 m/s2g_\text{exp} = 2 \times \text{slope} \approx 9.80\ \text{m/s}^2.

Percent error calculation (Table 1 example)
Let gtheo=9.806 m/s2g_\text{theo}=9.806\ \text{m/s}^2, gexp=9.80 m/s2g_\text{exp}=9.80\ \text{m/s}^2

%error=∣9.80−9.8069.806∣×100%≈0.06%.\%\text{error} = \left|\frac{9.80-9.806}{9.806}\right|\times100\% \approx 0.06\%.

Table 2 — alternate method (g from each height)
Compute gg per height using g=2s/tˉ2g = 2s/\bar{t}^2.

Height ss (m) tˉ2\bar{t}^2 (s²) g=2s/tˉ2g = 2s/\bar{t}^2 (m/s²) % error
0.50 0.1024 2×0.5/0.1024=9.772\times0.5/0.1024 = 9.77 0.37%
1.00 0.2025 2×1.0/0.2025=9.882\times1.0/0.2025 = 9.88 0.77%
1.50 0.3025 2×1.5/0.3025=9.922\times1.5/0.3025 = 9.92 1.16%

Sample calculation (step-by-step)

  1. For height 1.00 m, avg time tˉ=0.450\bar{t}=0.450 s, tˉ2=0.2025\bar{t}^2 = 0.2025 s².

  2. g=2s/tˉ2=2(1.00)/0.2025=9.8765 m/s2.g = 2s/\bar{t}^2 = 2(1.00)/0.2025 = 9.8765\ \text{m/s}^2.

  3. Percent error = ∣(9.8765−9.806)/9.806∣×100%≈0.72%.|(9.8765-9.806)/9.806|\times100\% \approx 0.72\%.

Chart/plot instructions

  • Plot ss (vertical axis) vs t2t^2 (horizontal axis).

  • Add linear trendline and report slope ± uncertainty.

  • Compute g=2×slopeg = 2\times\text{slope} and include uncertainty propagation: if slope uncertainty is Δm\Delta m, then Δg=2Δm\Delta g = 2\Delta m.

Notes about attachments

  • I cannot attach images here; when you prepare the lab file: include (a) a scanned photo of Table 1, (b) the plotted graph (s vs t2t^2) with trendline and equation visible, (c) screenshots of calculation steps. Use high-contrast photos and crop tightly so numbers are legible.

  • Save your spreadsheet table as an image (PNG/JPG) or export the plotted chart as PNG.

  • Label axes (distance in m, time² in s²), include units and best-fit line equation (e.g., s=(4.90) t2+0.003s = (4.90)\,t^2 + 0.003).

Compensation and Pay Perspectives

Board of Director Compensation

Some experts argue that a corporation’s board of directors should be paid only with stock options. What do you think?
Exempt or Non-Exempt
Remind us of your ideal future career. In that role, would you prefer to be compensated as an exempt employee or a non-exempt employee? Why or why not?
Minimum Wage
What are your thoughts on the minimum wage? Should the federal minimum wage be increased? If it were solely up to you, what would you increase the minimum wage to, and why?
Compensation and Pay Perspectives
Pay Secrecy
Do you want to know how much your coworkers earn? How eager are you to tell them how much you earn? Is pay secrecy a valid management tool to prevent jealousy and morale problems, or is it an unfair practice that hides discrimination and ineffective compensation policies? Who is best served or protected by the practice of pay secrecy?

Emotional Intelligence in Leadership

Each week, you will be presented with a series of critical thinking prompts and application prompts.

Please copy/paste the prompts into an offline document (Word, for example) and compose your responses offline (be sure to save your work).  Then click on the “Submit Assignment” button above, copy/paste your work into the text box ( please be sure to include the prompts prior to your responses), and click “Submit Assignment” at the bottom of the page.

Each question is generally worthy of,  at a minimum, at least 250 words (2-3 well-written paragraphs) in response for the open-ended types of prompts.  Be sure to connect with (and informally  cite in-text) the applicable readings/videos from the module’s learning materials.

A note on in-text citing and connecting with the learning materials:   As a graduate student, it’s  very important that you offer perspectives and arguments that are grounded in the literature –  NOT simply personal opinion or anecdotal evidence. I don’t want a works-cited page, but I do want you to clearly cite your sources in-text for the various connections you’ll be making between the learning materials and your application thereof.  For example, one might write,  “While I marveled at the uncanny ability of the psychic to tap into my true personality, the Barnum Effect  (Aronson, 2022, p. 117) could have well explained my feelings…”   Be sure to use these informal in-text cites to make your arguments and to support your perspectives.

Emotional Intelligence in Leadership

These are all open-ended prompts/questions, each deserving of a well thought out response. Again, that generally means two to three well-constructed paragraphs (about 250 words on average) per prompt.

The following exercise includes the following four prompts:

Critical Thinking/Application Prompt 1:   Go online and do a bit of research.  Locate two case studies that illustrate an organizational leader with low EI who has wreaked havoc on a team and/or organization. Preferably explore studies that relate to your own field (either the one you are currently working in or a field you intend to move into soon – i.e., after graduating with a graduate degree).  Summarize and comment on the cases.  Finally, if possible, comment on any ethical implications connected to the leader’s behavior.

Critical Thinking/Application Prompt 2:  

1. Read the first chapter of  On Dialogue:  “On Communication.”

2. Based on what you have read — in both Senge and Bohm — share your analysis of David Bohm’s explanation of what leads to ineffective listening.  What are we doing when we are not listening effectively?  What exactly do we need to pay attention to?  What is the process by which effective listening goes askew?  Be sure to share your own thoughts on Bohm’s views.  I am looking here for a summary of Bohm’s perspective and your own thoughts on the matter.

Critical Thinking/Application Prompt 3:   What the hell is “the proprioception of thought” and why does it matter to a person interested in developing leadership through emotional intelligence?

Critical Thinking/Application Prompt 4:   With regard to the field of “organizational leadership” specifically, go online and examine a couple of scholarly articles related to “the application of EI in organizations” — preferably related to your own field (either the one you are currently working in or a field you intend to move into soon – i.e., after graduating with graduate degree).  Describe what you found and share what you learned.

Resources attached for part A

 

Instructions Part B

In each module, you will have the opportunity to participate in an online discussion forum.

For this week there is again only one initial prompt that you need to address.  Respond to at least three classmates; and again, try to make some connections to folks that you have not chatted with yet this semester.

Hot Tip:  It might be helpful to copy-paste the discussion prompts into an offline document (Word, for example), compose your responses offline, and then return to copy-paste your responses here.
