...Introductory Speech Did you know that the Ford Mustang is the only muscle car that has remained in constant design and production for almost 5 decades? From the 1964 ½ model to today’s 5th generation model, the Mustang still remains as one of America’s top selling muscle cars. Not many people would choose their muscle car to compare themselves to but you will see my car, the Ford Mustang, and I are characteristically similar in several ways. Like the Mustang, I am strong- like the car’s engine. I am reliable and dependable and still going strong after almost 5 decades and many physical revisions. The engine of the Mustang is strong and powerful and symbolizes my strength, both mentally and physically, to endure the many hardships I have had throughout my life. I was in a fatal car accident at the age of 2 that killed 4 people in the other car. I sustained a large head would that required 64 stitches across the back of my head and I also had 2 crushed ankles. My parents were told that I would most likely never walk again. I underwent many reconstructive surgeries on my ankles and spent over 6 months in casts that started at my toes and went to the tops of my thighs. My persisting strength became evident after the casts were removed and I began to walk once again. As I got older, I was able to play many sports like softball and basketball and never allowed anything to slow me down or get in my way. It just goes to show that a strong will can trump any doctors’...

...As a Communications major I have learned to appreciate the work of PR agents. As CoCo Chanel has said before, “In order to be irreplaceable, one must always be different.” In my first two years as a college student, I wanted to know the honest appreciation of the production side to an event; however, I have now cultured the inns and outs of producing an event. Individual interpretations of major events, The Victoria Secret Fashion Show, New York City Fashion Week, bring varied insights to an agents capabilities and it is also interesting to point out important props that the agent has added emphases to. I have always been a perfectionist, but throughout my first degree, an A.A in Fashion Merchandising, I have greatly sharpened my critical thinking and creative skills. Instead of focusing on being a perfectionist, I have learned to continuously find motivation from all over the world right at my fingertips and to believe in everything that I successfully produce. Also, by having the opportunity to assist backstage at many events, fashion in-particular, and work with a well-known PR agent on different charity events; this has helped me to develop a broader horizon on the knowledge of a career field as such. I guess you can say that my appreciation and knowledge has matured in respect to the career field of PR, which has enlightened my inner creativity to shine on my future. Being a creative perfectionist had always been a skill of mine, but it was challenging to take the first...

...animals, volunteering with different animal rescue foundations, and starting to gain experience working with animals hands on. Introduction: You can say that my passion for animals goes over the line towards obsession, especially for ones such as my favorite animal, the giraffe. Now when it comes to taking that and making it my career, I have chosen to take the harder path and go for my Doctorate’s Degree to become a fully licensed veterinarian. While researching how difficult it would be to gain acceptance into the College of Veterinary Medicine at the University of Florida, my dream college, I found out that I will require more than just my ultimate passion for animals to be able to obtain my degree in veterinary medicine. In today’s speech, I will share with you guys my incentives for making my passion for animals my career choice which includes: my ownership of various animals, volunteering for various animal rescue foundations and my working experience with animals hands-on. My initial impulse for choosing this career began with my ownership of various animals When I was younger, my first pets just included your average dogs and cats. From then until now, I’ve owned a wider variety of pets. Transition: As if having that amount of animals wasn’t enough, my devotion for animals led me to volunteer for various animal rescue foundations. Knowing that I need volunteering experience to apply to veterinary school in the future, I searched for opportunities throughout high...

...By partaking in three unique scenarios of both elastic and inelastic collisions, I was able to conclude that speed and velocity are both conserved. This conclusion was made through the change in velocity of a cart relative to its "crasher". For example: throughout the different-mass elastic collisions, the speed that which the cart started and ended were equivalent - indicating that there was conservation of speed, in addition to the complete transfer of velocity. However, in the different-mass elastic collisions, the transfer of the speed of the cart was not complete, but instead, the lighter cart moved quicker than the heavier cart. This shows us that although force may be the same, the transfer of momentum shows us why the lighter cart moves more quickly than the slower. Throughout our previous unit, we described the constant velocity of objects in motion. That laid the basis for this next unit, where we will be studying why and how the object moves the way it does, specifically the "push" or "pull" of force. The heavier cart in a same-direction elastic collision seems to push the lighter cart, which causes an increase in speed for the lighter cart. Although we may have brushed on the surface of movement, this unit will pave the path for further investigation on velocity as well as momentum. According to today's lab, it is possible to measure the mass of the carts and then multiple the mass by the velocity to determine momentum. These two things will be related to almost...

...One copy of the lab report Physics 1030L/ Section 2 Conservation of Momentum Lab performed: 2/18/13 Report submitted: 2/20/13 Sample Calculations Results The magnitudes of the masses for the gliders before the collision were: mass XA1 is equal to 0.107m, and mass XB1 is equal to 0.101m. The magnitudes after the collision of the masses were: mass XA2 equal to 0.0890m, and mass XB2 equal to 0.0820m. The momentum of the masses before collision were: mass PA1 equal to 0.3737 (kg m/s), and mass PB1 equal to 0.3551(kg m/s). The momentum after collision of the masses were: PA2 equal to 0.3109 (kg m/s), and mass PB2 equal to 0.2886 (kg m/s). When considering the direction of the vectors the area of uncertainty is small when considering the area of both parallelograms of uncertainty, because the overlapping of the parallelograms is only a small portion of each. The momentum was partially conserved within the error range of the parallelograms, or the portion where they overlap. Conclusions 1. It is necessary that they glide on a cushion of air, so that they can avoid any friction which would slow down their movement and could possibly keep them from colliding. The friction would differ for each mass, and would change all the predicted values. If the masses were not on an air cushion, it is impossible to predict that the two masses would ever collide because of the differing frictions for each mass. 2.If the masses were...

...EUROPEAN QUALIFYING EXAMINATION 2009 PAPER A ELECTRICITY / MECHANICS This paper comprises: * * Client’s Letter Client’s Drawings 2009/A(E/M)/e/1-8 2009/A(E/M)/e/9-14 2009/A(E/M)/e -1Client’s Letter Dear Mr. Nedland, [001] My name is Pierre Aronnax. I am professor of marine biology and an enthusiastic hobby diver. I have invented a valve for a snorkel. [002] All too often, a breathtaking coral reef seduces the snorkeller to dive deeper under water. When the free end of a conventional snorkel submerges, i.e. plunges completely below the water surface, its breathing tube fills with water. Upon resurfacing the snorkeller has then to blow the breathing tube free of water before drawing another breath through the snorkel. Different snorkel valves are on the market, which prevent water from entering the breathing tube. These snorkel valves automatically close the free end of the snorkel when the snorkel submerges. [003] The most well-known of these snorkel valves is sold by Nemo Tubes Ltd. under the name "Nautilus". Fig. 1 shows a snorkel equipped with a Nautilus valve. Figs. 2A-2C show a Nautilus valve in use. [004] Snorkel 1 has a J-shaped breathing tube 2 with a mouthpiece 3 at one end. At the other end of the breathing tube 2, a tube portion 5 of a mushroom-shaped snorkel valve 4 is releasably fixed. Alternatively, the tube portion 5 may be integrally formed with the breathing tube 2. [005] The tube portion 5 opens into a hemispherical end piece 6. As can...

...Introductory speech instructions The purpose of this assignment is to get you started with public speaking in a relatively informal context. The instructor will assign one of your classmates to be your partner, and you will develop a speech designed to introduce your partner to the rest of the class. How to construct your speech: 1. First, get to know your partner! Ask lots of questions about your partner’s background and their interests. Look for major points of interest—such as hobbies, life events, or unique experiences—and ask your partner to provide you with more detailed information about them. These major points of interest will become the main points of your speech. And of course, you should be sure to return the favor by answering all of your partner’s questions about you. 2. Once you think you have enough material to work with, start outlining your speech. Use brief sentences to write out an introduction, a thesis, two main points, and a conclusion. Your thesis (and therefore, your speech) should address the following question: what kind of person is my classmate? Think about two qualities or attributes that describe your partner. Your classmate could be someone like: a sports fan, a musical talent, an outdoorsman, a car enthusiast, a spontaneous free spirit, or anything else that comes to mind. Be creative! 3. Once your full-sentence outline is completed, you can start rehearsing your speech. Be sure that your speech is not written out word-for-word;...

As stated in the lab procedure, we kept one mass heavier than the other and made the heavier object collide with the lighter object at rest. Looking back, there wasn’t too much difference between the sizes of the mass. There was only a 300 gram difference in the system and that may have helped in keeping the collision elastic. The speed was recorded as .404 m/s and that also may have helped in causing the object at rest to bounce off the moving object. We were not able to complete the inelastic collision part of the lab because we were not able to make the objects stick together. We were not sure if the plane the objects were set on was level and this may have caused the objects to keep bouncing away from each other. We also kept the weight and velocity (roughly) the same...

...American University in Cairo Department of Physics Final Exam Physics (111) Time: 2 Hours Answer the following problems 1)The mass of the blue puck in Figure is equal to 1.2 the mass of the green one. Before colliding, the pucks approach each other with momenta of equal magnitude and opposite directions, and the green puck has an initial speed of 10.0 m/s. Find the speeds of the pucks after the collision if half the kinetic energy is lost during the collision. speed of Blue puck: 5.89 m/s Speed of Green puck: 7.069 m/s 2)The speed of a moving bullet can be determined by allowing the bullet to pass through two rotating paper disks mounted a distance d apart on the same axle as shown in Fig. From the angular displacement of the two bullet holes in the disks and the rotational speed of the disks, we can determine the speed v of the bullet. Find the bullet speed for the following data: d = 80 cm, = 900 rev/min, and = 31.0°. The velocity of the bullet =139.35 m/s 3)A block of mass m1 = 2.00 kg and a block of mass m2 = 6.00 kg are connected by a massless string over a pulley in the shape of a solid disk having radius R = 0.250 m and mass M = 10.0 kg. These blocks are allowed to move on a fixed block-wedge of angle = 30.0 as in Figure P10.37. The coefficient of kinetic friction is 0.360 for both blocks.

...Conclusion We have learned from this Rotational Energy experiment that rotational energy is pretty powerful. We learned how to actually calculate and configure our own values for rotational energy rather than collecting them from a problem in the book, and actually use them to achieve our purpose of landing the ball into the cup. We did not achieve our purpose, but we did get pretty close in a couple of our tries. This experiment showed us how rotational energy worked and how it can account for many things. We had to calculate multiple things to find the rotational energy and then find the distance at which we need to place the cup. We needed to know the height of not only the table but the ramps as well. We needed to calculate exactly where the ball would land after it left the ramps and was in free fall to the floor. That is where we should place the cup so that the ball will land in the cup. Our calculations we not 100% correct as we did not make it into the cup. Some of the uncertainties that could have accounted for us not making the ball into the cup would be incorrect measurements. We could have accidently misread some of our measurements. Also we did not account for the height of the cup, so where the ball would normally land it would miss the cup because the cup’s opening was too high. Also we did not account for friction in our calculations, so that could have caused some caused some calculations to be slightly off. Also the wooden balls may not have been perfectly...

...Measurement of the moment of inertia of a flywheel A flywheel of radius R is set up on a horizontal axle of radius r. A string of length h is wrapped round the axle with a mass m tied to the end (Figures 1 and 2). The moment of inertia of the flywheel and axle is I. The flywheel is accelerated by the couple applied by the mass m. The mass is allowed to fall through a height h at which point the string leaves the axle. The velocity of the falling mass at this instant is v and the angular velocity of the flywheel ω. The potential energy lost by the weight is converted into kinetic energy of the weight, kinetic energy of the flywheel and heat due to friction in the bearings. If the energy lost per revolution due to friction is E and the flywheel makes n1 revolutions during acceleration, then: mgh = ½ mv2 + ½ Iω2 + n1E The flywheel is then allowed to come to rest due to the frictional couple. If it stops after a further n2 revolutions then: ½ Iω2 = n2E Therefore: mgh = 1/2 mv2 + 1/2 Iω2 + (n1/n2)1/2 Iω2 = 1/2 mv2 + 1/2 Iω2(1 + n1/n2) We could convert linear velocity (v) into angular velocity (ω) if we wished using v = Rω. Now the angular velocity ω at the end of the period of the acceleration is given by: ω/2 = 2πn1/t Since ω>/2 is the average angular velocity of the flywheel and 2πn1 is the angular distance covered by any point on it in a time t. Hence the moment of inertia of the flywheel can be...

...Christopher Betts SPC 2023 Personal Reflection Essay When it came to preparing for the introductory speech, I had to spend a lot of time thinking about what I wanted to share to the especially when most of them did not know me whatsoever. After long and hard thinking about the objects I wanted to bring in that would help reflect myself to the class I came up with three really good things in the end that ended up telling a lot about myself. I also have to admit I felt some anxiety before giving the speech to the class even though I feel as if I do not have much anxiety when it comes to speaking. I think the anxiety came from giving information about myself to a room full of people whom I am not familiar with. The thought of having a good first impression in front of all my classmates is where I believe most of the anxiety came from but after the first time getting through it I never found that to be the problem with the rest of my speeches. I have to admit that my public speaking skills have not gotten better as the more speeches were assigned. I am very disappointed in myself that I am currently not where I should be, especially being a senior in college. I need to prepare more thoroughly before speeches and make sure everything is not only organized on paper but in my head which involves having to practice over and over again by reciting my speech before class. I think this would help my speeches go smoother. I also need to pick topics to speak about that interest me...
