In an MRI machine the gradient magnets create ‘image slices’ of whichever part of the body is being scanned. A certain part of the body can be selected and focused on simply by changing the gradient magnet slightly. The coil is made for different parts of the body that are being scanned, and can be made for shoulders, knees, elbows, ankles and various other parts. The part of the body that is being imaged will be next to the coil. The coil is the part of the machine that will actually make it work, by giving of a radio frequency.
Use a protractor to measure the angle from the reference line to the lines drawn in step 6. 8. Record the angle created by the laser pointer through the air as the Angle of Instance and the angle created by the laser pointer through the water as the Angle of Refraction. 9. Use Snell's Law to determine the Index of Refraction of Water.
This is when the experimenting or observing is done, all the raw data is recorded and compiled to be analyzed c. Analyzing and Interpreting Data: Once the questions are created, the planning and carrying out of the investigation has happened, the data is analyzed and interpreted. This is when all the raw data is manipulated mathematically, categorically, graphically, or other ways to be able to make sense of the scientific inquiry. This is when the original questions are answered either that they were correct or incorrect. What went wrong and explaining what the results of the data mean. 2.
Finding Ka and pKa values of Bromothymol Blue with Spectrophotometry Lancaster Weld* Greg Maggard (*-Primary Author) There are numerous ways that chemists, and other scientists, find the value of equilibrium constants. In this experiment, the equilibrium constants Ka and pKa were determined using a spectrophotometer. In part one of the experiment, four cuvettes were prepared for part 2 of the experiment. In order to prepare these four cuvettes, 0.401g of NaH2PO4 and 0.400g of Na2HPO4 were placed in a 150 mL beaker. Next, 50 mL of distilled was placed into the 150 mL.
PK-S Lab 03 – Lab Report Name: ____________________ Section: ___________________ EXPERIMENT 3: Trigonometric Measurements Procedures: 1. Experimental measurement of the angles and sides of a right triangle: A. Create a triangle by taping a string against a wall and taping the bottom of the string to the floor or a table set against the wall. Make sure that the wall is perpendicular to the floor or table by measuring angle C, which should be 90o. B.

Complete the questions on the prelab page. Introduction: There are many different chemical methods that can be used to determine the concentration of a solution. You have already used one method, titration, to find the concentration of Ca+2 ions in a sample of water, and another, density, in finding the concentration of ethanol. In this lab you will use a method called visible spectroscopy to determine the concentration of a solution of CoCl2.
To completely view the moon’s pattern I will observe it during its zenith. To complete this observation I will use a variety of instruments to compare the different sizes of the moon I will get. The most critical instrument during this scientifical experiment is the basic cardboard paper towel cylinder. The cylinder provides the measurement that will display the estimate of the moon’s size by measuring in one-eighth inch in diameter. I will also have a ruler on hand to give me the measurements of the observations.
This process is called: A. mydriasis. B. myopia. C. miosis. D. macula. Answer Key: C Question 4 of 20 1.0 Points The round opening in the iris that allows light rays to enter the internal eye is the: A. retina.
Employed the use of Visual PinPoint in order to astrometrically reduce the images and to embed World Coordinate System data into the FITS header. Utilized data found in Sergeant (1974) paper concerning globular cluster positions. Used a procession calculator, found online, to convert the coordinate system from the outdated 1950 Epoch to the 2000 Epoch. Proceeded to plug in Sergeant's data into the calculator and re-checked for any errors. Used a digital development filter set to a kernel low pass more in MaximDL.
Purpose- The purpose of this lab was to help explain how the eye sees different wavelengths as colors. This is congruent to what we’re being taught because it helps further the understanding of wavelengths (including frequency, spectrum, emission etc.) also it shows the effect other chemicals have in a chemical reactions. Procedure- -Fill a 250-mL beaker halfway with distilled water. -Get six wooden splints that have been soaked in water.
