Lab: investigating hooked law with springs Purpose: to find spring constants of different springs using the slope of a graph of change in heights vs. the weight force. Also‚ to be able to understand how spring constants change when you add springs in a series or paralle Pre lab predictions: We predicted that the graph of gravitational force (mg) as a function of stretch (delta x) would look like Data: Spring #1: y = 8.2941x + 0.0685 This table represents the different distances that

Crystal Chand 4/21/15 Unit One Music Appreciation Lab Questions 1. Describe some of the influence of Latin music in the US in the early part of the twentieth century. Answer: Latin bands were becoming a popular ballroom and club attraction‚ Afro-Cuban music was also developing and spreading. One major step for this music style was the Woodstock performance of then little known Afro-Cuban band Santana from San Francisco back in 1969. 2. What was the significance of “Machito and His Afro-Cubans? Answer:

The purpose of this lab was to use gas chromatography to determine the relative amounts of the three components of gas products from the dehydration reaction of 1- and 2-Butanol with sulfuric acid and the dehydrobromination reaction of 1- and 2-Bromobutane with potassium tert-butoxide. E1 reactions are two-step unimolecular reactions. The first step of an E1 reaction occurs when a leaving group‚ which consists of a weak base‚ leaves an organic compound‚ leaving an intermediate carbocation. In the

Unit 5. Lab. New Building-Wired and Wireless If I choose to design the new building with a wired network the main benefit is there would be a low chance on interception. Choosing a wired network will also have a lower risk of security issues; reliability and speed are primary benefits as well when using physical connections in a wired network. The basis of the new building will relay on loads of data to be moveable that is why a wired network allows the control. Wired LANs provide superior performance

of the specialized underlying structures of these life-forms. In order for us to appreciate these special adaptation‚ we first need to know how a typical plant or an animal cell organelle behaves in different water and solute concentrations. In this lab‚ we will determine the effects of hypertonic‚ isotonic and hypotonic solutions on plant and animal cells. In general when an animals cell’s placed in hypertonic solution it shrivels; a plant cell on the other hand undergoes plasmolysis. When an animal

Toxicology Lab 1. In this investigation‚ a wide range of concentrations of Sodium Chloride (NaCl) solution were created and the effects that they had on radish seeds were tested. This ultimately created a doseresponse experiment in which it was detectable whether or not radish seeds were a reliable bioassay for the toxicity of NaCl. The goal of this experiment was to determine a correlation between toxicity and seed germination/radicle

Lab 5 The Diffraction Grating Chinua McDonald Objective: To measure the wavelength of light with a diffraction grating. Theory: The two types of diffraction gratings are the transmission and reflection gratings. They are made by ruling on a piece of glass or metal a number of evenly spaced lines with a fine diamond point. Diffraction phenomena can be analyzed in terms of Huygens’ principle‚ according to which every point on the wave front of a wave should be considered as a source
