Express your answer in terms of any or all of the given quantities and , the magnitude of the acceleration due to gravity. You did not open hints for this part. ANSWER: Archimedes’ Principle Learning Goal: To understand the applications of Archimedes’ principle. Archimedes’ principle is a powerful tool for solving many problems involving equilibrium in fluids. It states the following: When a body is partially or completely submerged in a fluid (either a liquid or a gas), the fluid exerts an upward force on the body equal to the weight of the fluid displaced by the body. As a result of the upward Archimedes force (often called the buoyant force), some objects may float in a fluid, and all of them appear to weigh less. This is the familiar phenomenon of buoyancy. Quantitatively, the buoyant force can be found as , where is the force, is the density of the fluid, is the magnitude of the acceleration due to gravity, and is the volume of the displaced fluid. In this problem, you will be asked several qualitative questions that should help you develop a feel for Archimedes’ principle. An object is placed in a fluid and then released. Assume that the object either floats to the surface (settling so that the object is partly above and partly below the fluid surface) or sinks to the bottom. (Note that for Parts A through D, you should assume that the object has settled in equilibrium.)

ANSWER: Now apply what you know to some more complicated situations. Part E An object is floating in equilibrium on the surface of a liquid. The object is then removed and placed in another container, filled with a denser liquid. What would you observe? You did not open hints for this part. ANSWER: for every object submerged partially or completely in a fluid for an object that floats only for an object that sinks for no object submerged in a fluid for every object submerged partially or completely in a fluid for an object that floats for an object that sinks for no object submerged in a fluid Part F An object is floating in equilibrium on the surface of a liquid. The object is then removed and placed in another container, filled with a less dense liquid. What would you observe? You did not open hints for this part. ANSWER: Part G Two objects, T and B, have identical size and shape and have uniform density. They are carefully placed in a container filled with a liquid. Both objects float in equilibrium.

For this assignment, you will compose a letter designed to recruit students to join and support the agenda of one of three nonexistent student organizations that, were they to exist, would likely be very unpopular. The student organization for which you will be recruiting is determined by your last name: The first letter of your last name is… Your student organization assignment is… A – F The SETS Collective: SETS (Skip the Elevator, Take the Stairs) is dedicated to energy conservation on campus, particularly by eliminating elevator usage by pedestrians in any buildings on the UT-Austin campus. G – N O – Z Your recruiting letter must include eight (8) different persuasive strategies. Each strategy must be used in the service of encouraging students to join the organization and/or endorse its cause. In addition to your recruiting letter, you will also submit a commentary describing the different strategies you used in the recruiting letter. In this course, we utilize the TurnItIn tool. This service helps educators prevent plagiarism by detecting unoriginal content in student papers. In addition to acting as a plagiarism deterrent, it also has features designed to aid in educating students about plagiarism and importance of proper attribution of any borrowed content. For more information, please visit http://turnitin.com/. Below are a series of requirements for the paper assignment. Failure to satisfy these requirements will result in substantial point penalties. Also, failure to abide by the academic honesty policy described in the syllabus and maintained by the CMS department, the Moody College of Communication, and/or The University of Texas will result in a grade of F on the assignment and referral to the Dean of Students. Assignment Requirements • You must portray yourself as a recruiting officer (or Secretary of Recruitment) – not the President, VP, etc. – of the organization described in your letter. As a recruiting officer, you are not authorized to offer any rewards or bribes (gifts in the form of sports tickets, free meals, etc.) to people as an incentive to join the organization, nor are you allowed to make up fictional incentives (e.g., OBC students will enjoy an opportunity to participate in international conferences). Your letter should focus exclusively on the merits of joining the organization based on commitment to its cause. • Assume that organization has just been formed – i.e., do not portray it as having existed prior to the Spring of 2017. • You may also assume that there are currently only three members of the organization, the president, vice-president, and yourself (the Secretary of Recruitment). You CANNOT claim that there are “many members.” • You must use the following format for the recruiting letter AND the commentary: 12-point Times New Roman font, single-spaced (NOT double-spaced) on 8.5 X 11-inch white paper with 1-inch margins on all sides. • The recruiting letter must be no shorter than 2 nor longer than 3 pages; the commentary must be no longer than 2 pages. • Your recruiting letter must include only 8 (eight) DIFFERENT strategies discussed in the lectures and/or readings. You may use any principle/theory we have discussed EXCEPT for balance theory (which is too obvious) or deception (which isn’t persuasion per se). • Your commentary must identify the name OR what you did for of each strategy (e.g., Door In Face or Foot In The Door) used in your letter and describe the specific purpose(s) the strategy was used to achieve. At a minimum, your description of each strategy should consist of at least two complete sentences (16 sentences total). • Each strategy explanation in your commentary should be bulleted or numbered for easy identification • You may not lie under any circumstances. Lies include falsifications and/or distortions of the truth about the student organization (e.g., SURF is endorsed by the Fellowship of Christian Athletes). Also, you may not offer recruits bribes in any form (tickets, discounts, free food, cash, etc.) as an incentive for joining the organization. • Your completed assignment (recruiting letter + commentary) must be turned in on April 13th (a Thursday) at or before 9:30 a.m. Grading Rubric We will use the following rubric to evaluate and grade your letter + commentary. Assignment Component Possible Points Obtained Points Format, Spelling, Grammar, Coherence Are the letter and commentary written in the proper format? Do they consist of grammatical, coherent English sentences? Has the assignment been spell-checked? 4 Strategy 1 Example/Commentary Is the example an acceptable instance of the strategy?

Make a large (but reasonable) request to target  World you lend me $50? o 2. After request is rejected, make a smaller request  Well then, could you lend me $10? o Creating a “big” favor out of thin air! “low-balling” • An advantage is offered that induces a favorable purchase decision. Then, sometime after the decision has been made, but before the bargain is sealed, the original purchase buyer is deftly removed. 1.) Loss framing: Loss aversion 2.) Restriction: scarcity 3.)

For this assignment, you will compose a letter designed to recruit students to join and support the agenda of one of three nonexistent student organizations that, were they to exist, would likely be very unpopular. The student organization for which you will be recruiting is determined by your last name: The first letter of your last name is… Your student organization assignment is… A – F The SETS Collective: SETS (Skip the Elevator, Take the Stairs) is dedicated to energy conservation on campus, particularly by eliminating elevator usage by pedestrians in any buildings on the UT-Austin campus. G – N O – Z Your recruiting letter must include eight (8) different persuasive strategies. Each strategy must be used in the service of encouraging students to join the organization and/or endorse its cause. In addition to your recruiting letter, you will also submit a commentary describing the different strategies you used in the recruiting letter. In this course, we utilize the TurnItIn tool. This service helps educators prevent plagiarism by detecting unoriginal content in student papers. In addition to acting as a plagiarism deterrent, it also has features designed to aid in educating students about plagiarism and importance of proper attribution of any borrowed content. For more information, please visit http://turnitin.com/. Below are a series of requirements for the paper assignment. Failure to satisfy these requirements will result in substantial point penalties. Also, failure to abide by the academic honesty policy described in the syllabus and maintained by the CMS department, the Moody College of Communication, and/or The University of Texas will result in a grade of F on the assignment and referral to the Dean of Students. Assignment Requirements • You must portray yourself as a recruiting officer (or Secretary of Recruitment) – not the President, VP, etc. – of the organization described in your letter. As a recruiting officer, you are not authorized to offer any rewards or bribes (gifts in the form of sports tickets, free meals, etc.) to people as an incentive to join the organization, nor are you allowed to make up fictional incentives (e.g., OBC students will enjoy an opportunity to participate in international conferences). Your letter should focus exclusively on the merits of joining the organization based on commitment to its cause. • Assume that organization has just been formed – i.e., do not portray it as having existed prior to the Spring of 2017. • You may also assume that there are currently only three members of the organization, the president, vice-president, and yourself (the Secretary of Recruitment). You CANNOT claim that there are “many members.” • You must use the following format for the recruiting letter AND the commentary: 12-point Times New Roman font, single-spaced (NOT double-spaced) on 8.5 X 11-inch white paper with 1-inch margins on all sides. • The recruiting letter must be no shorter than 2 nor longer than 3 pages; the commentary must be no longer than 2 pages. • Your recruiting letter must include only 8 (eight) DIFFERENT strategies discussed in the lectures and/or readings. You may use any principle/theory we have discussed EXCEPT for balance theory (which is too obvious) or deception (which isn’t persuasion per se). • Your commentary must identify the name OR what you did for of each strategy (e.g., Door In Face or Foot In The Door) used in your letter and describe the specific purpose(s) the strategy was used to achieve. At a minimum, your description of each strategy should consist of at least two complete sentences (16 sentences total). • Each strategy explanation in your commentary should be bulleted or numbered for easy identification • You may not lie under any circumstances. Lies include falsifications and/or distortions of the truth about the student organization (e.g., SURF is endorsed by the Fellowship of Christian Athletes). Also, you may not offer recruits bribes in any form (tickets, discounts, free food, cash, etc.) as an incentive for joining the organization. • Your completed assignment (recruiting letter + commentary) must be turned in on April 13th (a Thursday) at or before 9:30 a.m. Grading Rubric We will use the following rubric to evaluate and grade your letter + commentary. Assignment Component Possible Points Obtained Points Format, Spelling, Grammar, Coherence Are the letter and commentary written in the proper format? Do they consist of grammatical, coherent English sentences? Has the assignment been spell-checked? 4 Strategy 1 Example/Commentary Is the example an acceptable instance of the strategy?

Make a large (but reasonable) request to target  World you lend me $50? o 2. After request is rejected, make a smaller request  Well then, could you lend me $10? o Creating a “big” favor out of thin air! “low-balling” • An advantage is offered that induces a favorable purchase decision. Then, sometime after the decision has been made, but before the bargain is sealed, the original purchase buyer is deftly removed. 1.) Loss framing: Loss aversion 2.) Restriction: scarcity 3.)
