In general, the experiment succeeded in demonstrating free-fall by dropping a tennis ball. Distance and time were documented to calculate velocity and acceleration, the quantities involved in linear kinematics. Graph 1 (distance vs. time) suggests a commonsensical relation - longer distance yields longer time. The only exception is at 1.0 m, where its time value (0.42 s) is less than that of a shorter distance (0.5s for 0.5 m distance). Average time was used to construct the graph, and there…

To do this experiment you will need two subjects that have different arm lengths. In this experiment Subject 1 had an arm length of .81 meters and Subject 2 had an arm length of .77 meters. It is crucial that the subjects have different arm lengths because if they don’t your results will be invalid. The first step in this experiment is to set up the camera using the tripod and insert an SD card. Next, position the camera perpendicular to the sagittal plane along the x-axis in regards to the…

Laboratory Exercise 1: Anatomy Lab Report Scientist: Eryka Ocasio Ramos Lab Title: Scientific Method and Measurements I. Problem: Is there a correlation between the length of the upper and lower limbs and the height of an individual? II. Hypothesis: The length of a person’s upper limb is equal to 0.4 (40%) of the height of the person. III. Variables: Independent Variable: The people chosen for the experiment. Dependent Variable: Height and upper limb length. IV. Constants: Units of measure, the…

Have you ever seen a movie where the new girl walks into a new high school and doesn’t know what to expect? Particularly, that happened to my classmate, Alyssa Sarino. Alyssa is a sixteen year old new junior attending Rancho Mirage High School. Her quiet looking appearance might fool people because she has a bright persona in her. Alyssa grew up in Banning, California and lived there all of her life until this summer. Her family and herself moved to Cathedral City with her uncle and aunt. “My…

In the next step, the graded response IRT model will be analyzed again for each identified domain, but without the excluded items, and the model fit statistics will be assessed. If the model has a good fit statistics, the best item for each domain will be selected according to the distribution of the threshold values across the latent scale and the discrimination value; item that has threshold values cross the whole latent scale and high discrimination value will be selected. Sample Size Graded…

Mr. John H. Smith, President Smith’s Bubble Gum Company, LLC 123 Street Drive, Somewhere, ST 01234 Hearing Conservation Program Proposal Dear Mr. Smith, Thank you for your inquiry about a hearing conservation program for your company. I’ve provided an outline of a hearing conservation program with OSHA guidelines and costs for you to consider. To clarify some of your questions, the abbreviation of dB stands for decibels, which is how acoustic power is measured. Since the human ear…

We can easily convert this into Cartesian form by replacing z by x+iy |(x+iy)-(-3 +2i)|=5 |(x+3) + i(y-2)|=5 √(〖(x+3)〗^2+〖(y-2)〗^2 ) =5 or 〖(x+3)〗^2+〖(y-2)〗^2=25 Which is the exact form of a Cartesian equation of a circle with a center of (-3, 2) and a radius of 5 We could check if a particular point lies on the circle Ex. z2=1-3i Substituting into the equation of the circle, with z replaced by z2=1-3i |(1-3i) - (-3 + 2i)|=5 |4-5i|=5 √(4^2+〖(-5)〗^2 ) =5 41=5, which is not true, thus z2 does not…

Rude vs. Mean vs. Bullying: Defining the Differences Signe Whitson, Huffington Post, Posted: 11/26/2012 8:29 pm EST Updated: 08/27/2014 10:59 am EDT A few weeks ago, I had the terrific fortune of getting to present some of the bullying prevention work that I do to a group of children at a local bookstore. As if interacting with smiling, exuberant young people was not gift enough, a reporter also attended the event and wrote a lovely article about my book and the work I do with kids, parents,…

Marx’s Bushy Mustache When people think about Karl Marx, they think about a mustache-twirling villain, but Marx’s mustache was too bushy to twirl. Marx is commonly misconstrued as a villain when in reality he was just a man who shared his thoughts. Karl Marx caused a paradigm shift in the way people think about the social economic structure of the world, created and led the communist revolutions and indirectly led some of the most influential revolutions in history. Karl Marx changed the way…

Introduction The propose of this experiment was to see if we could conducted an experiment that we could elect data and act our hypothesis about sordaria. We hypothesized if tan and black sordaria got placed together to cross over, we could expect out of 50 sordarias that 27 would cross over and 23 would not cross over. Some research has brought up some discussion about how much tan or black sordaria is one the agar square to begin with. (Kitani 1961) If these numbers are more than the other,…
