Experiment 6 Newton’s Second and Third Laws PHY 2091- 01 Experiment Performed : 03/2/15 Report Submitted : 03/20/15 Lab Partner: Nicholas Bautista Instructor: Introduction The experiment determines newton’s second and third laws using real life experiments such as the mass pulley system using the Atwood’s machine and using springs (2) in series and parallel to determine their spring constants and extensions when a mass is hanged from them. Newron’s second law states that the force

A New Dream of Politics – a poem by Ben Okri They say there is only one way for politics. That it looks with hard eyes at the hard world And shapes it with a ruler’s edge, Measuring what is possible against Acclaim, support, and votes. They say there is only one way to dream For the people, to give them not what they need But food for their fears. We measure the deeds of politicians By their time in power. But in ancient times they had another way. They measured greatness by the gold

Purpose of investigation: To test the theory of sorting. This suggests that the further up the beach, the larger the pebbles. This is due to constructive waves having a large swash, meaning they have the energy to carry large sediment up the beach. The energy then percolates down into the beach meaning it only has a weak backwash and can only carry the smaller sediment back down, progressively depositing it down the beach so the largest is at the top and the smallest is at the bottom. Methods

說明如何將假設測定的邏輯運用在交叉表的分析上。 4. 以五個假設測定的步驟說明卡方測定，以及正確的解釋測定的結果。 5. 說明卡方測定的限制，以及統計顯著性與實質重要性的差異。 貳、簡介 本章要介紹的Chi Square (χ2) test（卡方測定）大概是社會科學研究中，最常看到的一種假設測定方法。這是因為此測定方法相當容易符合假設測定第一個步驟─基本假定設定─的要求。此測定方法是兩個名目尺度變項間之假設測定的方法。因此在level of measurement 的要求方面是最基本的nominal level of measurement。這名目尺度變項不限於是二分的，也可適用在其他尺度測量的變項上。而χ2 test也是一種無參數的測定，因此在基本假定部分，我們無須知道母群體之分配特性（distribution-free）。χ2之抽樣分配是一種已知之理論分配，就叫χ2分配。（所謂Chi Square是χ這個希臘字母的發音加上「平方（square）」的英文）。 這種可以相當容易符合基本假定要求的無參數測定方法，可以讓我們在做拒絕虛無假設的決策時，比較有信心。這是因

Lab report Aim: to be able to find out the effect of light intensity on the rate of photosynthesis Hypothesis: I think that as the light intensity will increase or the light source will get closer, the plant will produce more oxygen meaning more bubbles will be produced. Therefore the photosynthesis will become quicker Materials: power pack, elodea plant, lamp, test tube, room temperature water, thermometer, ruler, stopwatch Variables Independent-changing light intensity or the distance of the

Basic Skills and Concepts 21-28 Determine which of the four levels of measurement (nominal, ordinal, interval, and ratio) is most appropriate. 21. Voltage measurements from the author’s home: Interval 22. Types of movies (drama, comedy, adventure, documentary): nominal 23. Critic ratings of movies on a scale from 0 stars to 4 stars: Ratio 24. Actual temperatures (in degrees Fahrenheit): Interval 25. Companies (Disney, MGM, Warner Brothers, universal, 20th Century Fox): Nominal

figure above for the required measurement. It will be used also in measuring the coins that have been pitched, flicked or shooted by the specific workers. PENCIL Pencil will be used to draw the required lines on the top of the table such as 3 inches and 21 inches from the yardstick as shown in the figure above. TAPE The tape is used to attach the yardstick in the top of the table conside- ring the the required measurement in this experiment. TWENTY-FIVE

EXERCISE-11 1) What demographic variables were measured at least at the interval level of measurement Education is measured at the interval scales because the data is measured on specific intervals, and grades of education. 2) What statistics were used to describe the length of labor in this study? Were these appropriate? Length of Labor is measured in hours. It is s an appropriate measurement because the time measured is less than a 24 hours. 3) What other statistic could have been

companies that per sues high standards, the employees must be efficient and effective by control measures. The types of control measures used to see how efficient and effective an employee is by observation, performance appraisal and reports. There a lot of ways to measure an employee’s performance in a call center: responsibility on the job, capabilities and abilities, and communication skills. A responsible employee must be on time at work, have discipline towards co-workers and, customers and be respectful

step is to carefully mass each piece of equipment provided by the equipment supplier; this includes the flask, graduated cylinder, pipet, and beaker. Place the flask on the digital scale and record the mass in a notepad. Be sure to clear out the measurement displayed on the scale after removing the flask from the balance. Repeat this process using the graduated cylinder, pipet, and beaker by interchanging the flask for the new piece of measuring equipment. The third step is to fill the burette with
