Lab 1 helps create a better understand of the changes in crystal structures when the annealing and quenching process is applied to 1020 and 1080 steel. The numbered steel refers to the ASTM grain-size number. Formula 1 is used to solve for the grain size. n=2^(G-1) Equation (1) at 100x magnification Crystal structures change shapes which changes the strength of the material and its properties. The metal might become soft, brittle, hard, or ductile.
The design relied on two Schmitt triggers to generate the two different tones while using the transistors to act as a switch. This causes it to trigger continuously between two unstable states, allowing automatic switching between two frequencies producing two different tones. The RC values between the two Schmitt triggers will differ. Capacitors charge and discharge faster when it’s resistance is smaller.
For most sequences at position 4 and 5 we observe only the nucleotides G and T, respectively. There may be rare cases where other nucleotides may also be found. To consider such observations, we need to do a process called additive smoothing or Laplace smoothing to smooth the categorical data. [9] In this case, we add 4 sequences: AAAAAAAAA, CCCCCCCCC, GGGGGGGG, TTTTTTTTT.
I need to find the area of rectangle ABCD. I know that ABCD is a rectangle with diagonals intersecting at point E. Segment DE equals 4x-5, segment BC equals 2x+6, and segment AC equals 6x. I predict that To find the area of rectangle ABCD I need to find out the base and height of the rectangle. The first step is to find what x equals. Since I know the intersecting line segments AC and DB are congruent that means when I times the equation 4x-5 for segment DE by two it will equal the equation 6x for segment AC.
1. The test subjects will prepare for sleep by acquiring everything needed for the subjects’ sleep preferences. 2. The test subjects will all set alarms on their smartphones for approximately 6, 8, and 10 hours after the subjects’ enter the resting period (Subjects may wake during the resting period for the bathroom, but they must not stay awake for more than ten minutes at a time to prevent as much deviation as possible.). 3.
Experiment 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.

Using the data provided in each one of these tests it can be assumed that one has done the steps to be able to determine the magnitude and orientation of the charges of the tape in each test, thus, allowing them to apply the same principle to any object they so desired. Their results would line up with the following; that if the two pieces of tape are torn from the same 40 centimeter strip then the tops of both pieces of tape would be positive and the bottoms of both pieces of tape would be negative and that if they would double the tape the attraction or repulsion in general would lower due to the increased density. Their data would also show that two pieces of tape ripped from each other would result in one piece being entirely positive and the other being entirely negative, they would also be able to state that the orientation of how the tape is paired up doesn’t matter.

1. There are two ways of maximizing points in this experiment. The first one is that I should connect myself to a vertex that is in the biggest component and purchases immunization. Since the probability of being infected is based off of expected value, I would have less than 1% chance of getting infected. The second way is that I try to make myself stay in the second-largest connected component.

The disk of the sun was dull silver as though it were nearer and not so hot, yet the air stifled.”
This is only the temperature of the outer shell of the sun, the photosphere (“The Sun”) The core of the sun is 15.7 million kelvin, and the pressure makes it a perfect place for nuclear fusion. Protons are merged together in the sun’s core, which forms helium. This helium is what gives the sun its life energy, and if the sun ever runs out, it will turn into a white dwarf star. The sun is highly magnetic due to the fact that it is made of plasma.
Joey Erberich GEOS 109 September 28, 2014 Lab Report #2 The Sun, Size-Wise The sun is the largest star in our solar system, and also the largest object all together. It is basically a huge ball of highly magnetic plasma that was formed 4.6 billion years ago. The sun provides the warmth needed for the earth, and holds a core temperature of 15.7 million kelvin.
Introduction: Prism adaptation is a form of visual-motor learning that triggers the visual-motor system to adapt to a new visuospatial field that has been altered by the use of prism goggles. The use of these prism goggles alters the visual field, and forces the visual cortex to integrate its feedback mechanisms to relatively correct somarosensational errors made by the body while moving. As a result of this, neural mechanisms and the fundamental principles behind this adaptation can be used clinically to treat patients who have experienced the ill effects of visual-spatial deficits. Therefore, the purpose of this lab was to examine the motor adaptation is response to altered visual inputs. I hypothesized that the prism exposure, and the post-exposure conditions will result in a greater horizontal displacement between the balls and the midline of the felt than the pre-exposure condition.
