Group Lab Report *
Title of Experiment: Date: Class, Section & Lab group: Recorder (consolidates report and submits into dropbox): Group Members PRESENT
* Before beginning, save this report on your desktop with the Recorder's last name appended.
1. This data should result in a bell curve when graphed as a histogram. Note, that since each student only has between 10 and 20 data points, the graph may not appear identical to a bell curve but should have a most frequent measurement value.
2. In Excel, create a histogram.
3. If each student conducted the experiment in an identical fashion, could the data be combined into a larger data set? If so, use all data sets as if it were just one data set and average every three readings. Create a new histogram of this averaged data set and discuss it. How does this new combined histogram compare with your individual histograms?
4. Does your group see signs of systematic uncertainty? How would this affect the combined bell curve? Do you think that combining data from different experimenters is a generally accepted way to measure data in an experiment? What possible problems do you see could happen? Explain.
Experimental Procedure and Data Collection for Activity II:
1. Open the “Charges and fields” PHET simulation to map the electric field around one or more
point charges. Click on the positive charge of 1nC and move it into the middle of the simulation
field. Check voltage, grid and values.
2. Take the e-field sensor and measure the field at the following distances from the charge: 0.2m,0.5m, 1m, 1.5 m 2m, and 2.5m. Record your measurements in an excel spreadsheet.
3. Add 3 more charges and repeat your measurements. When you look at your data, what can say about the relationship between the different parameters. Discuss.
4. Add another set of 4 positive charges at 2m on a straight line from the original cluster. Where
is the electric field greatest? Is there ever a point where the field will be zero?
5. Replace one of the clusters with 4 negative charges at 2m from the positive charges. Where is the electric field the greatest? Is there a point where the field will be zero?
R-2
6. Construct a parallel plate capacitor where a second line of charges equal in size and opposite
in charge are placed at a distance of 1m from a line of positive charges. Examine the e-field with
a sensor. What can you say about the e-field between the plates?

Task 3-b:
If you have two instruments used to measure the temperature of two points inside the factory (point A and
point B). The true temperature for point A is 25 C, while the true temperature for point B is 30. However,
the measured values for the first instrument were 26 and 30, while for the second instrument, the measured
values were 25 and 29.
i)
Define using your own words the sensitivity drift and bias drift, then explain how these types
of error could affect the measured values of the sensors.
ii)
of these two instruments against different temperature values (between 0 – 100 C). Assume
Analyze the accuracy and error for both instruments by calculating and plotting the response
linear relationship between the input and output for these instruments.
Based on your calculations, specify the type of drift that affects each sensor (sensitivity drift,
bias drift, or both).
iv)
Which of these error types can be corrected using calibration?

I have a wooden toy train that runs on wooden tracks. I would like to place two ESP-WROOM-32 Boards on top of the train. Broadcast communication (which involves radio frequency, not Wi-Fi) would help communicate about the train's lateness to five other wooden trains on the same track. Local communication would help communicate to the train station about the train's lateness. I would also need radio frequency Tx-Rx Modules for discharging and undergoing the signal, and repeaters just in case the signal loses power due to long-distance traveling. My wooden train should be automated. It should run at 4 inches per second, keep a minimum distance of 30 seconds away from the other wooden trains, and make a 17-second-long stop every 500 seconds.
