I need help about 4 article about finance after reading Wall Street Journal from 8/21/2017-8/27/2017

Set up the experiment

1. 1. Get four 8 oz. cups from the lab kit. Place a piece of tape on each cup or glass. Using a pen or marker, label the tape on each cup with one of the following percentages: 0%, 1.75%, 3.5%, and 7%.
   2. Using the graduated cylinder, measure out 100 mL of distilled water. Pour the water into the fifth, unlabeled cup.
   3. Measure out 1.5 level teaspoons of salt and add it to the unlabeled cup containing 100 mL of distilled water. Mix completely. This is the 7% salt solution.
   4. Using the graduated cylinder, measure out 50 mL of this mixture and pour it from the graduated cylinder into the cup labeled 7%.
   5. Add distilled water up to the 100 mL mark of the graduated cylinder to make the next dilution. Adding 50 mL distilled water to 50 mL of a 7% solution will result in 100 mL of a 3.5% solution.
   6. Using the graduated cylinder, measure out 50 mL of the 3.5% solution and pour it from the graduated cylinder into the cup labeled 3.5%.
   7. Add distilled water up to the 100 mL mark of the solution in the graduated cylinder to make the next dilution. Adding 50 mL of distilled water to the 50 mL of the 3.5% solution will result in 100 mL of a 1.75% solution.
   8. Using the graduated cylinder, measure out 50 mL of the 1.75% solution and pour it from the graduated cylinder into the cup labeled 1.75%.
   9. Empty the remaining 1.75% solution down the drain of the sink and rinse out the graduated cylinder with tap water.
   10. Using a sharp steak or kitchen knife, slice eight pieces of potato exactly 10 mm x 10 mm x 40 mm (1 cm x 1 cm x 4 cm). It is critically important that these potato core pieces are cut as precisely as possible; they need to all start out having the same volume. A single- edge razor blade may work better than a knife.
   11. Determine the volume of the potato cores. The volume, is calculated by multiplying the width x height x length. Therefore, each core starts out with a volume of 4,000 cubic millimeters or 4 cubic centimeters. Measure the cores with both the mm ruler and the calipers. Measuring with the calipers to the nearest millimeter will be good enough for this lab. Create a data table like the one below to record the beginning and ending volumes.

   Table 1. Potato core measurements

   	0% salt solution	1.75% salt solution	3.5% salt solution	7% salt solution
   Beginning average volume (cu mm)
   Ending average volume (cu mm)
   Percent difference

   12. Place two measured cores into each solution overnight, or for at least 8 hours. That time period is not critical to the results; it can be longer.
   13. Remove the cores from one of the cups and pat them dry with a paper towel. The solution may now be discarded down the drain of a sink.
   14. Using the caliper, measure the height, width, and length of the cores, and then determine the volume of each core. Average the measurements for the two cores and record in the data table above. The cores can now be discarded.
   15. Repeat Steps 13 – 14 three more times: one time for each cup.
1. Illustration of the Importance of Surface-to-Volume Ratios
   1. Calculate the surface-to-volume ratio of the following potato cubes:
      1. CUBE 1: Length, width, and height are all 5 mm
      2. CUBE 2: Length, width, and height are all 3 mm
   2. Effect of cell size on diffusion rate
      1. With clean hands, cutting board, and knife, cut the skin off of the potato.
      2. Using the knife, cut two cubes of potato with dimensions of 1 cm x 1 cm x 1 cm.
      3. Using the knife, cut two cubes of potato with dimensions 1.5 cm x 1.5 cm x 1.5 cm.
      4. Using the knife, cut two cubes of potato with dimension of 2 cm x 2 cm x 2 cm.
      5. Place distilled water into a cup or glass. Add the vial of food coloring to the water until a dark color is achieved.
      6. Carefully place the potato cubes in the solution. The cubes must be completely submerged in the water. Let them stand in the solution for 2 to 4 hours.
      7. After 2 to 4 hours, remove the cubes. Using the knife, cut each cube in half.
      8. Using the ruler, measure how far the solution has diffused into each potato cube.
      9. Record the results. A sample data table is included below that may be used to organize and record the results.
      10. Complete the following calculations to determine the rate of diffusion and record the results.

   Rate of Diffusion (cm/min)= Distance of diffusion ÷ time.

   Cube	Distance of Diffusion	Rate of Diffusion
   1 cm cubed
   1 cm cubed
   1.5 cm cubed
   1.5 cm cubed
   2 cm cubed
   2 cm cubed
   	Average Rate of Diff.

• Create your own 3D design – starting from an example, or starting from nothing ( I did it, you will find it in this link: https://www.tinkercad.com/things/0VTiV5sHWZD-mug )

• • I used this website to create my 3D design: https://www.tinkercad.com (Links to an external site.)Links to an external site.
• What you have to write a description of:
• What you created ( I created a mug for any kind of drink include a light in the bottom )
• Why you created it ( it shows the temperature of the drink inside the mug. if it is could , the mug base will be blue. and if it is hot, the mug base will be red. also, the base of the mug has a sensor)
