Record all the mass measurements for Penny Set B. 3.) Using a 100-mL graduated cylinder and the water displacement technique, measure the volume of 1 penny from Penny Set A (Pre-1982). Then, find the volume of 2, 3, 5, 7, 9, and 13 pennies. Record all volume measurements for Penny Set A.
Then compare the precision and accuracy of the data to the literature values for pre and post 1892 pennies when using various numbers of coins. Then determine the density of the coins. We will have to set up data sheetsin orders to record and calculate the data. 0% Cu, ~100% Zn 50% Cu, ~50% Zn 10% Cu, ~90% Zn 60% Cu, ~40% Zn 20% Cu, ~80% Zn 70% Cu, ~30% Zn 30% Cu, ~70% Zn 80% Cu, ~20% Zn 40% Cu, ~60% Zn 90% Cu, ~10% Zn Procedure: 1. Find the mass of the 5 dry pennies, then record the data.
Because when you plug the binary numbers into the 8 bit conversion table, the two zeros before the 10 equal nothing. So 10 and 0010 have the same decimal number. 128 64 32 16 8 4 2 1 128 64 32 16 8 4 2 1 1 0 = 2 0 0 1 0 = 2 3. Based on the breakdown of the binary and decimal systems in this lab, describe the available digit values and the first four digits of a base 5 numbering system. You can use the binary system as a reference, where the available digit values are 0 and 1 and the first four digits are 1, 2, 4, and 8.
Both of these formulas were found on page 225 in Mathematics in Our World (Bluman, 2005). Problem #37 • This sequence is geometric • Ending balance is $814.45 STEPS/CALCULTATIONS YOU PERFORMED TO REACH THE ANSWER: To find the ending balance, the formula of An = a1(rn-1) will be used. The initial balance is $500, the interest is 5%, and the time span is 10 years. 5% will be listed as 1.05 as the initial balance is 100% plus 5% interest, so 105% is written 1.05. The number of terms is n=10, the first term is a1=525, the common ratio is r = 1.05.
* We kept the foam block (metal in the box) at the end of the ramp. On the jack(an equipment which is used to vary heights), the top of the ramp was placed on it. * The Light gates detector was placed at the finishing point of the ramp. * Like in method 1, the five different heights : 0.10m, 0.15m, 0.20m, 0.25m and 0.30m were taken. * The final speed was recorded by the light gate detector about three times for each height.
The dependent variable was the average time spent on the shape drawn within sixty seconds. The standardized variables were the type of pen and sharpie used, the size of the shape (circle) the termites were placed in, and the maximum time (60 sec.) given for the termites to be observed. There were two levels of treatment, which were red ink pen and red ink sharpie. The sample size was 100 termites and there were 5 replications for each level of treatment.
b. One inch on this map equals exactly __24,000___ inches in real life. c. One inch on this map equals exactly _0.3__ mile(s) in real life, so we can say that 1 inch on the map equals approximately 1/3 mi on the ground. (Lab Man) 3 6. Review how the location of point x in Fig.9.5 in 9th ed’n was determined using PLS shorthand (see caption for Figure 9.5). Then, determine the location of point V in the Figure below using PLS shorthand.
I added varying levels of substrate to the test tubes in each experiment. The amount of substrates were .5 grams, 1 gram, 2 grams, 4 grams, and 8 grams. The output of the experiment (the dependent variable) was the number of molecules of product formed per minute at (106). RESULTS Test Tube # | pH Level | Amount of Substrate | Number of Molecules of Product Formed per Minute (106) | Test Tube #1 | 3 | .5g | 19 | Test Tube #2 | 3 | 1.0g | 39 | Test Tube #3 | 3 | 2.0g | 82 | Test Tube #4 | 3 | 4.0g | 96 | Test Tube #5 | 3 | 8.0g | 96 | | | | | Test Tube #1 | 5 | .5g | 39 | Test Tube #2 | 5 | 1.0g | 81 | Test Tube #3 | 5 | 2.0g | 168 | Test Tube #4 | 5 | 4.0g | 198 | Test Tube #5 | 5 | 8.0g | 198 | | | | | Test Tube #1 | 7 | .5g | 72 | Test Tube #2 | 7 | 1.0g | 145 | Test Tube #3 | 7 | 2.0g | 300 | Test Tube #4 | 7 | 4.0g |
We moved around the weights until we ended up with what we saw to be an even leveled meter. We repeated this a second time using two slightly different weights and recorded them. Our third trial was done in a slightly different way, instead of having a single weight on each side, we placed two masses on the right side of the meter stick and only one on the left. Again, we played with the weights until we were at equilibrium and recorded our data. The second half of the experiment was done in a similar fashion, except the ruler was no longer hung on
Lastly we will explore standing waves and how string oscillations become affected by the string mass density. Theory As stated in order above, our first experiment of simple harmonic motion using an oscillating spring setup. By using a mass hanger attached to a rotary motion sensor, we are able to produce graphs and data to attempt to show the proofs for the theories and equations listed in the theory and graph section of the lab. The experiment started with adding 200g and progressively moved up to 350g for five trials. We then collected the data and analyzed the sine graph and the different portions of it and what they meant including the parameters and taking proper data.
