Question:
Is it true that the laborer is only interested in what he receives, i.e., his wage, and not interested in what he gives, i.e., that he does not derive satisfaction from the work itself?
ANSWERTo address the question directly, I feel that in most cases the worker is mostly interested in thewage, and slightly interested in the labor. I have had days at my job where I have worked…

Laboratory Exercise For Plate Tectonicsearthquakes Related To A Hypothetical Pla
/in Uncategorized /by developerLaboratory Exercise for Plate Tectonics
Earthquakes Related to a Hypothetical Plate Boundary
Lesson Description
In this exercise we will plot 40 theoretical earthquake events at the juncture of two tectonic plates. Students will then analyze the pattern of earthquake locations and compare these patterns to possible plate boundaries.
Learning Objectives
Student will learn to recognize the earthquake patterns associated with plate tectonic boundaries.
Step One
Plot the Earthquake Data found in Table #1 onto the Area Map (Figure #1). Feel free to duplicate this map to use as work copies. Place a dot or small circle on the map to represent each earthquake event (epicenter). Next to your earthquake location write the value of the depth at which that earthquake occurred (focus).
Step Two
Using the East-West Crossection (Figure #2) plot the surface location (epicenter) of each earthquake and then, based on the depth related to each earthquake event, plot the earthquake focus. On the crossection trace the top and bottom of the plate based on the earthquake focus depths.
Step Three
Answer the following questions.
Question #1: Does the pattern of deep and intermediate earthquakes indicate a tectonic plate boundary? If so, describe.
Question #2:Â Is it possible to predict the thickness of this plate? How thick could this plate be? Does this thickness relate to a continental plate or oceanic plate? Oceanic plates are not 100 kilometers thick, discuss what then could account for the apparent thickness of this descending plate?
Question #3:Â Can a second pattern be found that could be describing the other plate? Describe.
Figure #1:Â Area Map
Figure #2: Â Crossection

/in Uncategorized /by developerLaboratory measurements always contain some error. Depending on the type of equipment used, that error can be quite substantial. One way to validate our density value from Part B is to do a completely different experiment to measure of the density of the block, then compare the two measurements
cube mass in air is 50.0 g
cube mass immersed in water is 5.6g
water temperature is 20 degree Celsius
density of water is .99821
previous calculation of density of the block immersed 40% was 1.16 g/cm^3

The bubble wrap shown in the figure below is often used to protect fragile objects during shipping. Bubble wrap tends to pop when stepped onto or squeezed. How can you explain this using Boyle’s Law?
then please provide a conclusion for the experiment:
Conclusions:
Your conclusion should include the following:
What did you learn from this experiment? Base your conclusions on experimental observations. A proper conclusion connects the experiment results back to key principle(s) stated in the background section. This should be a stand-alone paragraph that summarizes how the data supports the purpose and why.
