Pendulum Investigation Introduction In this investigation, I will try to attempt an experiment that will measure the time taken for a pendulum to oscillate for one complete swing; I will also explore and investigate the numerous variables that might effect the time taken to oscillate. Factors effecting periodic time =============================== The factors, which might affect the time taken for a pendulum to complete one swing, are: 1. The length of string 2. Weight
Determining Acceleration Due to Gravity The Determination of the acceleration due to gravity at the surface of the earth, g, using a simple pendulum. Aim: The determination of the acceleration due to gravity at the surface of the earth, g, using a simple pendulum Background ========== All bodies exert gravitational forces on one another. A large mass, such as the
Piece of thread (≈ 110 cm) Stop watch Two small wooden blocks metre rule Hypothesis and Theory:- In this experiment the set up below is arranged. This is a simple pendulum system which is a simple harmonic motion. In the figure below consider a small mass m attached to the end of a length l of wire. The other end is attached to a fixed point P and the mass oscillates along the arc. Suppose the mass during the motion at a point B at an instant,
Factors Affecting the Time Period for Oscillations in a Mass-spring System When a mass is attached to the end of a spring the downward force the mass applies on the spring will cause the spring to extend. We know from Hooke's law that the force exerted by the masses attached to the spring will be proportional to the amount the spring extends. F = kx When additional downward force is applied to the spring we can cause additional tension in the spring which, when released, causes the system
exactly does this definition mean? Some fallacies about wisdom include: confusing wisdom with intelligence, having a college degree, having common sense, or simply having life experiences. In order to prove these fallacies wrong, the definition of wisdom needs to be explored. The dictionary meaning of wisdom included the words sagacity and erudition. Sagacity, according to the dictionary, means “quickness of discernment; shrewdness; high intelligence (pg 292).” Erudition means “learning, knowledge gained
commonly used with interval or ratio level data (Corty, 2007). The data in the GPA is distributed and slightly skewed to the right, which means it has a positive skew and has a peaked distribution. The final histogram also has a leptokurtic frequency distribution, but is skewed to the left meaning this has a negative skew. Descriptive Statistics N Minimum Maximum Mean Std.

Most people go through life and always hear about the word respect, but they don’t know what it means. Respect is the esteem for or a sense of the worth or excellence of a person. There are things in life you need to hold in respect. Respect for yourself, respect for others, and respect for property. Respect is taught to people everywhere and it is even taught to them in their religions. Respect is the very aspect that keeps everything in your life. Respect for yourself is very important to a person
differences and similarities as well as situations where one of these methods should be used over the other. !!!Similarities and Differences __Z-tests__ are statistical calculations that can be used to compare sample and population means. The Z score
gain something you must also lose something in return. In this case you gain more time with friends,family, and studies, but you lose pay and may even irritate your boss. Less pay is obvious as you are working fewer hours so you get less money, which means your standard of living goes down. More time for leisure activities such as, friends and family gives you a closer bond with your friends and family. Working fewer hours could also irritate your boss, since you are making him either hire a new worker
The Kelly Criterion or sometimes called a Kelly bet is a formula used to decide the optimal sized stake of the bank to bet on a certain outcome. The way the Kelly Criterion works is that if one believes to have an edge over the bookmakers odds for a certain outcome one applies the kelly formula to calculate how much of their bank to stake and then do this for a series of bets resulting in a profit. Many argue the Kelly strategy is the strongest strategy among all betting strategies in the long term
Data Analysis The scientific question investigated in this experiment was, “Which household object, when catapulted at a 45 degree angle, will travel the farthest?” The hypothesis in this experiment was, “If four household objects are catapulted at a 45 degree angle, then the standard white dice will travel the farthest.” The independent variable in this experiment is changing the object launched. The dependent variable in this experiment is the change in distance traveled. The control variables
A Comparison of Broadsheet Newspapers with Tabloid Newspapers Investigation 1 Hypothesis 1 "Broadsheet newspapers have a longer average word length than tabloid newspapers" My theory is that broadsheet newspapers use a more complex style of language. In effect I think this will result in a longer average word length in a broadsheet than in a tabloid newspaper. Both newspapers will have a large amount of short word included in the articles, however, this can not be avoided due
in captivity their emotional health and physical health are negatively affected, On the other hand, some people foresee that keeping whales in captivity is a good idea, but I disagree. Many people ask, what does it mean for a whale to be kept in captivity? Being kept in captivity means to be kept or to live under human care as opposed to living freely in their natural environment. Whales are kept in captivity because many people think that whales are not safe in the wild and they are better off in
Comparing Left-Handed and Right-Handed People Are left-handed people more intelligent and creative than the right-handed in Mayfield High School? In my coursework, I am going to focus on the IQ, Key Stage 2 results, favourite colour, favourite subject and height of students in Mayfield High School. Specify, I will concentrate on the Year 7,8 and 9 boys and girls because these year groups have closer relationship with the Key Stage 2 results. In the following coursework I am going
Running head: Situational Influences on Purchasing Behavior Situational Influences on Purchasing Behavior Abstract There was an investigation in an attempt to understand what situational influences affect purchasing behaviors of consumers. Fifty subjects were asked to complete a survey in determining what attributes affect the decision to purchase a product. The effect of purchase was based on three different times of day: morning, afternoon
Investigating the Factors that Affect the Price of a Second Hand Car Introduction I am going to test which factors affect the price of a second hand car using a variety of different statistical techniques. From what I discover using these techniques I will conclude which factors are the most important. I will examine only cars within the reach of a normal family, i.e. not luxury cars. I will also exclude classic cars as these are unlikely to perform like normal second hand cars.
statistics is a set of disciplines for study quantitative information. Implied that several methods used to collect or process or interpret quantitative data from large amount of information, then finally generate a calculated number, for example average, mean, standard deviation…etc. All of these are the key reference for decision making or predicting consequences. Thus, it enables us to estimate the extent of our errors. Statistics was primely developed in 17th century. It was initially used in collecting

these are used? • Assumptions made • Worked example consisting of at least 3 gates • Pictures, tables and graphs if required. 1. CLOCK: Being students of Electrical Engineering, clock plays a vital role in our digital world. By mentioning clock, I mean “digital clock signal” (clk). It is basically a voltage signal which is similar to a square wave that consists of two voltage levels: High (varies with circuit necessaries) and Low (0). It is represented as follows: Many electronic circuits don’t
g a conversation about hospice care is never an easy one. However, how you approach the subject could mean the difference between a fruitful conversation or something a little more difficult. It's not always as easy as putting yourself in the other person's shoes because until you are in that position, you won't know how you are going to feel until you are the one facing an end of life decision. How to Begin the Conversation There are a few things you need to know before you begin the hospice care
