Physics experiment- creating lightning

Introduction

We’ve got the assignment to try to create lightning, by charging two balloons using your hair. When both balloons are electrically charged, you slowly move them towards each other and you should be able to create a spark.

What would we have done differently?

We came up with a few ideas to test if you can create lightning with the use of two balloons in a different way. Firstly we would use different sizes of balloons, to see if this influences the experiment. We would also use different shapes of balloons and different thicknesses of balloons. Finally we would use different types of hair (thick, thin, short, long) to examine if this has any effect.

Research question

Is it possible to create a spark by holding two statically charged balloons against each other?

Hypothesis

We think we will be able to see a spark, because the atoms in the balloon became ions (there is a difference in number between protons and electrons). We think that if we move the balloons slowly towards each other, the attraction of the protons in the positively charged balloon attract the electrons of the negatively charged balloon enough, to let them move from one balloon to the other and we will be able to see a spark.

Expectations

The electrical charge in these balloons must be a lot smaller than in lighting, so the spark is a lot smaller too. Since we’re trying to recreate lighting on a small scale, we expect that there will be sound as well as a spark.

Results:

When the balloons were rubbed against our hair, they made our hair stand up. When the balloons were brought together, there wasn’t any spark visible. There was, however, a sort of “tick”, the sound a spark usually makes. When we used thicker balloons, we still did not see a spark, only a “tick”. The different types of hair did not change the results,…...

It will explain what a job analysis is, and identifies the objectives of the job duties and roles for a position as a Human Resource Receptionist. Creating a Job Analysis The history of Job analysis was founded in 1900 by Frederick W. Taylor. His interest in improving the studying the principles of work and science developed into what is called a Job analysis. Human Resource Managers create a Job Analysis using task statements, Knowledge Skills Abilities, and create a job description. One method of developing a Job analysis is using the 7 stages of a Functional Job Analysis. The 7 stages are resources in helping to identify the task statements, KSA’s and job description. The following 7 stages are: things functions, work instructions, mathematical, data function, reasoning development, language develop and people function. (Pugh 2007) The thing functions are examples the ability to use office equipment anything tangible. Work instructions requires the ability to perform a given a task. Mathematical function is the ability to operate and handled business math. Data function is dealing with facts, statistics and information with business. Reasoning development show the ability to show comprehensive reasoning. Language develop require oral and written communication. People functions involve interaction with people. All 7 stages are used in developing the process of producing a Job......

How Lightning Works

...Lightning -During the water cycle, water molecules can gather in the atmosphere to form a cloud -As the process of evaporation and condensation continues in the water cycle, rising moisture may collide with precipitation falling from the sky. As a result of these collisions electrons are knocked off of the rising moisture, creating a charge separation - The newly knocked-off electrons gather at the lower portion of the cloud, giving it a negative charge. The rising moisture that has just lost an electron carries a positive charge to the top of the cloud. - When there is a charge separation in a cloud, there is also an electric field that is associated with the separation. Like the cloud, this field is negative in the lower region and positive in the upper region. - As the amount of charge builds up in the cloud the more intense the electric field becomes to the point where electrons at the earth’s surface are repelled deeper into the ground by the strong negative charge in the cloud. This causes the earth’s surface to have a strong positive charge. - When the electric field becomes very strong (tens of thousands of volts per inch), conditions are ripe for the air to begin breaking down. The electric field causes the surrounding air to become separated into positive ions and electron which means they are able to move much more easily. The ionization of air creates plasma with conductive and after the ionization process, the path between the cloud and the earth begins to...

In the twenty century, methodology has the same results; to make processes more efficient however some of the processes have changed. The twenty-century processes are supply chain management, business processes, feasibility studies, cost-benefit analyses (ROI) and capital budgeting. Regardless of the changes in the processes, the end result is to streamline the process, reduce paperwork and eliminate duplications. Methodology has been known to lower cost and improve customer satisfaction. Based on the case study titled “Creating a Methodology”, the executive staff had many concerns about implementing an enterprise project management methodology (EPM). The executive staff knew it was necessary to continue to compete in the request for proposal (RFP) process. In addition this was a requirement from corporate to implement a methodology. The reasoning for the executive staff hesitation is that they felt such efficiencies could result in a reduction in authority and workforce. In addition to learning a new process, there were concerns of them being to strict and not allowing enough flexibility. This would change the manor of doing business and additional time would be needed to create the methodology. Although some of the concerns are valid, the benefits of a......

Entrepreneurship, Entrepreneurial Organization: In (Metaprofiling, 2013)1 study about the entrepreneurial organizations they differentiated between two concepts, entrepreneurs and entrepreneurial organization. Successful entrepreneurs are opportunists who, through their creativity, drive and vision, create economic or social value. They challenge conventional wisdom by practicing disruptive innovation — innovation that creates new markets through the application of a different set of values. They change the rules of the game by questioning the status quo and upping the stakes. It follows that an entrepreneurial organization can be defined as: An organization that places innovation and opportunism at its heart in order to produce economic or social value. However, for many organizations, this is only a brief moment in their evolution. And according to (Rodrigues et al,2003)2 entrepreneurial organizations, in fact, reflect the basic characteristics of its leadership.

Wicker works very well because it is sturdy, flexible and relatively lightweight. The flexibility helps with balloon landings: In a basket made of more rigid material, passengers would feel the brunt of the impact force. Wicker material flexes a little, absorbing some of the energy.

Creating Capabilites

...Creating Capabilities: Income and Poverty In Creating Capabilities Martha C. Nussabaum suggests that measuring poverty using one’s income can be misleading and problematic when it comes to understanding the real reason why the person is poor. Nussabaum argues that poverty “involves heterogeneous failures of opportunity, which are not always well correlated with income” (Nussabaum 143). The problem with measuring poverty through the means of just income is outdated, there are many devastating factors that can greatly altar one’s living condition besides their income. As Nussabaum suggests, income is an inaccurate means in determining one’s well-being because other factors such as education, nutrition and debt could contribute to greatly altering one’s earnings, then causes them to go into poverty. This essay is to explain why measuring poverty through income is a problem. Nussabaum’s belief of why the measurement of poverty is determined by income is flawed and how it should not be used because, there are other factors that can greatly altar ones living conditions will be defined as: “Poverty involves heterogeneous failures of opportunity, which are not always well correlated with income; moreover, people in positions of social exclusion may have difficulty converting income into actual functioning, so income is not even a good proxy for capabilities”(Nussabaum 143-4).

Creating a Methodology

...Creating a Methodology July 20, 2015 Lanika Jones Project Management Dr. Christopher Hase   John Compton, the president of the company could not understand why his executive team waited so long to develop an enterprise project management methodology (EPM) for their company. Being that they knew about what steps, how to go about it the start up and the time frame are was going to take to execute this plan. But first when you think about a methodology what it is? A methodology a set of methods, rules, or ideas that are important in a science or art: a particular procedure or set of procedures. When Compton’s executive team was presented with this idea of creating a methodology for his company his team was stagnant with following through because they had to go through the change process. The change process is “when the employees’ initially refuse to admit to the need of change”(Kerzner 98). When a change process come into play when a employees refuse to admit or adapt to the need of change different corporate culture factors need to be put in to play in order for the Compton’s team EPM could be successful. Being that the team had to create a methodology the two cultures that I see fit for the beginning is cooperative cultures and competitive cultures. But in order for the team to understand these cultures is that “good cultures are teamwork, trust, communication and cooperation (Kerzner 99) from all member of the staff. Cooperative culture are base upon trust and...

The first contributing factor was the executives were afraid of losing their power and authority they had. I believe they knew by developing a Enterprise Project Management Methodology, that only one executive would be in charge and more powerful than the other executive's. The executives new at some point they would have to do it, but what they did not understand is by not developing an Enterprise Project Management Methodology they were putting the company’s growth and competitiveness in jeopardy. The second contributing factor was the executives had no clue on were to begin with developing an Enterprise Project Management Methodology. The executives were so afraid of who was going to be in control that they really never thought it out. The executive staff recommended 12 life cycles which would have increased paper work and less time to manage the project. A consultant was called in to assist them in creating an Enterprise Project Management Methodology explaining the pros of having.

Creating an Agenda

...Creating an Agenda Chris Abernathy SOC/110 John Koehler Creating an Agenda More and more meetings are now and will continue to be conducted without the benefit of being in the same room together. People are working from home or the other side of the planet, and it’s important to make these virtual meetings effective. Virtual meetings, which I define as anytime we discuss something with two or more people outside of the same room, can be done over the phone or on the web. And though there are many advantages to meeting with people in this way, there are also obstacles to making them work well. According to "Working In A Virtual Team" (n.d.), it is more difficult to fully understand each other because even the use of video can hide a great deal of non-verbal communication. We also interact differently when we’re not in close proximity to one another. Distractions abound and can easily be hidden from others. And the ability to build trust and camaraderie are especially difficult. All Meetings Should Include: * Agenda. Nothing frustrates people more than attending a meeting where there is no clear reason for it and no logical progression of topics to be discussed. * Check–in time. Take five minutes or so in the beginning for everyone to say something about what’s going on with them—professionally or personally. This gets everyone talking right away and helps facilitate camaraderie. * Schedule. Start and end the meeting on time, and keep the agenda moving......

Accent-Light Accent-lights serve the purpose of accentuating a subject. Typically an Accent-light will separate a subject from a background. Examples would be a light shining onto a subject's hair to add a rim effect or shining onto a background to lift the tones of a background. There can be many accent lights in a shot, another example would be a spotlight on a handbag in a fashion shot. When used for separation, i.e. a hair-light, the light should not be more dominant than the main light for general use.

Creating an Outline

...Creating an Outline An outline helps you arrange the order of ideas in a paper. Many students eliminate outlining in the writing process as an unnecessary step. However, writing an essay without an outline can create disjointed results. An outline provides a roadmap so that the essay can move smoothly from point A to point B to point C. Without an outline, the essay could easily become disorganized, e.g., A, B, A, C, B. This can confuse readers because the points of the essay are not arranged in correct sequence. Use the following suggestions to create an effective outline. Creating Correct Formatting The following information will help you format an outline correctly:  Include at least two elements under each of the sections in the outline. If you have only one element, however, you can add additional information to create at least two points.  Create parallel wording at the beginning of each section of the outline. If the first word begins with a noun, the first words in all other elements in that section must also begin with nouns. If the first word is a verb, the other elements must begin with verbs, etc.  Include a period, and space or tab after each letter or number. Be consistent on using spaces or tabs throughout. (See the sample outline below.)  Use double spacing in the outline for ease in reading or use single spacing throughout and double space between each of the major elements (I, II, II).  Capitalize the first word after each number...
