Date Submitted: 5/24/2015 Date Performed: 5/24/2015 Lab Section: Chem-180 Course Instructor: Professor Lea Stage Addendum to Lab 1: Physical and Chemical Properties. 1. Did you observe any chemical changes in this experiment? Yes, there was a variation of noted chemical changes in this experiment. 2. What evidence did you use to decide that something was a chemical change? There was an assortment of different changes indicating that chemical changes were taking place such as change in color or chemicals bubbling when combined with another chemical. 3. Give at least two examples of chemical changes you observed. 1. Magnesium substances color noted to turn white when heat was applied.
In Part 1 of the lab, a solar cell was created and tested for its capability to conduct electricity. After researching the processes that contribute to the conductive property, it was found that the oxidized substance is the dye, as it donates an excited electron to the titanium oxide. Consequently, titanium oxide is reduced before it donates an electron to the cathode. The electrolyte solution was found to replenish the dye with electrons so it could continue to act as a reducing agent.
FIGURE 1.7- A magnified view of a single lenslet shows a portion of an aberrated wavefront (red curve) passing through. If the wavefront had been flat (aberration-free), it would have focused to a point on the video sensor (CCD) on the lenslet's optic axis (yellow dot). Refractive errors distort the wavefront out of a plane, so a wavefront portion (red curve) enters the lenslet curved and tilted. The light will therefore be focused to another part (red dot). The dot will be shifted by an amount that is in direct proportion to the wavefront tilt.
Table.2 shown the best results of vertical resolution used in shorter pulse duration is better for the higher frequency and very similar for the 1 GHz, 800 MHz and 500 MHz. More which explains why the results obtained in Tables 3 was the same for both frequency. Because of the different materials used in the experiments metallic and wooden bars, the resolution show the metal bars are worsen, due to their higher electromagnetic contrast, amongst other things. The second reflector, so a bigger separation is needed to detect it as discrete events. This effect is more relevant when the reflectors are closer to the antennas and particular for the 500 MHz antenna (Table 3). The horizontal resolution obtained for the 1 GHz and 800 MHz is very similar and much better than for the 500 MHz. As expected, horizontal resolution worsens as the reflectors are moved away from the frequency, mainly because their footprint size gets larger. In radargrams (a) and (b) of Figs. 9, 11 and 13, the
P is the reflectance proportion of EMR, M is the outgoing reflectance and E is the incoming reflectance. So in order to find the reflectance we are dividing the outgoing (M) reflectance to the incoming reflectance (E).
For each point, you would add 7 to the x coordinate and then take away 1 from the y-coordinate.
to $0$, $R$ initially decreases from $\infty$ to $\sqrt{2 a_{0}}$ at $r= \sqrt{a_{0}}$ so will increase once
To calculate the effective diameter of the particles, we use Equation 1 provided below. To determine the effective diameter of the particles, we needed to have the hydrometer readings and temperature for each time taken, as well as using the Coefficient of temperature adjustment table provided in Appendix 3 and the Hydrometer 152H length readings in Appendix 4. To able to determine the Percent Finer for Hydrometer, we use Equation 2 provided below as well as Equation 3 for the Dry Weight of Soil provided below. For Equation 2, we also need the Specific Gravity correction for percent finer table to be able to solve Equation 2. The Specific Gravity correction for percent finer table is provided in Appendix 5. Furthermore, to determine the total
The estimated sample to be taken should be 9 lettuce plants/ roots to have the 95% level of confidence and within the 10% of population mean.
The board hardware inputs for A, B, and C are switches SW[2], SW[1], and SW[0], respectively. Add these input pins to your schematic. You will also need the complements of these signals as well and will need to add three not gates. Label the pins and wires as shown below, using Properties to change the names. If you forget how to do this step, refer to the wiring tutorial instructions, included as part 0 of this lab.
Lab one introduces the basic concepts and processes of remote sensing and gives a better understanding of multiband images, color compositing, and contrast enhancement. The following were the objectives for the lab to help introduce these concepts and processes:
From the Client VM, clear Internet Explorer’s cache (or completely close and reopen IE) and go to http://10.0.0.1 What do you notice? Record your observations. These observations will help you with your lab report. The web page does not load stating “Internet cannot display the web page.”

Vulnerability 1: Injection – used to attack the applications in which malicious SQL statements are inserted into an entry field for execution.
Governing of equations includes the equations related to first law of thermodynamics for steady flow processes within a control volume with multiple inlets and outlets. It can be expressed through the mass and energy rate balance equations. The mass balance equation for each component of the power plant is presented in Eq. 1.
