H Lab Report
I noticed that all 3 different substances provided had a different density. When I put about a ½ inch of the solution “H” it was very thick almost like a jelly consistency. In addition we added another unknown solution “M” into the same test tube that contained the substance “H” we observed that the substance slinked to the bottom of substance “H” and it started creating its own layer. The two layers of solution both did not mix together and was separated by some type of density suspension. Furthermore we introduced another unknown substance “G” This was the densest liquid sinking to the bottom. When we proceeded to add dye the dye was suspended in the middle of “H” and “M” it was the mixing point for the dye. Evidence that supports my claim

1764 Words | 8 PagesAnderson and Wood (1925) determined a magnification value equal to 2800 but they neglected the deformation of the tungsten wire under different equilibrium situations. Conversely, the deformation of the wire could be sufficient to reduce the magnification factor of 30%, increasing the moment of inertia. For this reason Uhrhammer and Collins (1990) and Uhrhammer et al. (1996) recomputed the instrument static magnification (GS) that was estimated equal to 2080 ± 60. Using 2800 instead of 2080 in the BB WA simulations leads to a magnitude error of +0.129 (e.g. Uhrhammer et al., 2011).

574 Words | 3 PagesExperiment 7 In this experiment we configured several DC circuits consisting of an emf and a network of resistors. The circuits were composed of a power supply, two DMMs, a circuit board, an SPST switch, and an assortment of known resistors along with one unknown resistor. We measured the current and voltage of the entire circuit as well as the potential drops across each resistor to determine the parameters of the circuit including the resistance, voltage, and current for each component.

155 Words | 1 PagesSuppose you need to find the fractional European call and the fractional European put options. Let the Hurst parameter be $H=0.85$, the $\sigma=0,25$, $r=0.10$, $S_{fbm} = 100$, $K = 95$, we have \begin{eqnarray*} d_1^{fBm} & = & \frac{\ln{\frac{S}{K}} + \frac{1}{2}(r( T - t) + \frac{(1)\sigma^2{( T^{2H} - t^{2H})}}{2})}{\sigma{\sqrt{T^{2H} - t^{2H}}}}\\ & = & \frac{\ln(\frac{105}{100}) + (0.10(0.25 -0) + \frac{(1){0.25^2}{0.25^{2(0.85)} - (1)0.25^{2(0.85)}}}{2}}{(0.25){\sqrt{0.25^{2(0.85)} - 0}})} \end{eqnarray*} we obtain $d^{fBm}_1= 1.0558$. We find in the normal distribution that $N(1.0558)= 0.8544$ and $N(-1.0558) = 0.1456.$

When police and medical examiners got to each crime scene, they learned that all of the hostages were given drugs and had overdosed on them. Some of the pills, in powder form, were found near the victims. One of the victims was stable enough to tell the investigators that the power on the floor were the drugs they were forced to take. The medical examiner found out each hostage was given either unknown A or unknown B.
Hexane Lab Report
1619 Words | 7 PagesSolvent used in the elution process would be the mobile phase and solvents of different polarity would have a significant impact on the separation due to the varying solubility of compounds in different solvents. Hexane, being the less polar solvent, interacts mainly with the less polar analytes but very slowly with polar analytes. Therefore using hexane at the start of the elution process allows the less polar compound to be eluted out first. After the complete collection of less polar analyte, the mobile phase was changed to the more polar hexane/ethyl acetate solvent, which has stronger interaction with the more polar component, allowing it to be eluted out faster. The change in solvents throughout the elution process would allow for an effective and efficient separation of the compounds β-carotene and chlorophyll in the crude extract of green leaves.
Chromatography Lab Report
1393 Words | 6 PagesMaterials and Methods: For the chromatographic separation of plant pigments, pieces of spinach were ground with acetone to produce a watery extract. A line of extract was applied 1 cm from the bottom of a strip of chromatography paper. The line dried and the extract was reapplied. Once that dried, the paper was placed into a jar containing a small amount chromatography solvent (small enough that the line was not drowned by the solvent) which is made of 1 part acetone and 9 parts petroleum ether. The lid was placed on the jar and was only removed once the pigments had separated and the solvent had almost reached the top.

716 Words | 3 PagesAll procedures for this lab was obtained from the Marshall University BSC 121 Principles of Biology for Majors Laboratory Manual (Weinstein, 2015). On September 22, students in biology 121 section 101 obtained nine pots to plant their respected peas. Once the pots were obtained, students placed paper towels in the bottom of the plots to keep the vermiculite from falling out. When the paper towels were placed in the pots, they were then filled up ¾ of the way full with vermiculite, and were watered adequately. Four shallow holes were then created with a finger, and were filled with peas.
Data Analysis Lab Report
1357 Words | 6 Pages\section{Reduction of \textit{Chandra} Data} \label{sec::chandra} To confirm the existence of a galaxy cluster, \textit{Chandra} X-ray observation is important as it provides an evidence for extremely hot intracluster medium (ICM), which is expected from such a deep potential well of a cluster. In particular, high spatial resolution X-ray images can be used to determine different properties of this hot ICM, such as gas temperature profile, gas density profile, and total hydrostatic mass. In this section, we describe how we reduce the data from a raw X-ray image taken by \textit{Chandra} to various ICM's properties. \subsection{Data Preparation} PKS1353-341 (OBSID 17214) was observed with \textit{Chandra} ACIS-I for 31 ks. The cluster has
Scientific Method Lab Report
314 Words | 2 PagesThe purpose of this lab was to familiarize the students with the Scientific Method. The Scientific Method is a set of rules that Scientists from all different fields use to create and develop theories. The basic steps of the Scientific Method are: to first observe and gather data, then create a critical question, next form a hypothesis, then create and conduct an experiment multiple times, next you will evaluate the results and or reject the hypotheses, finally if your hypothesis is correct you will publish your results. We used these steps to determine what the inner workings inside a particular black box. Our TA began by showing the class a particular black box.
