course mth163 I am not sure if this is all of the work for assignment one. I don't know if there is any text questions to submit. I saw questions in the reading of assignment 1, but am not sure if I am suppose to answer those and submit through a work submit form. Also, I don't understand if we are suppose to submit randomized problems and mine links for those did not work in assignment 1. ???????Y?????assignment #001001. `query1

16:30:53 Query Introduction to General Themes; Examples (no summary needed) What were some of the things in this introduction that you found interesting or surprising?
......!!!!!!!!...................................
RESPONSE --> I thought it was interesting that the data decreased at a deacreasing rate instead of a constant rate. By looking at it I would have guessed it would have been a constant rate of water flowing out of the tube. confidence assessment: 2

16:36:38 Query Introductory Flow Experiment (no summary needed) Is the depth changing at a regular rate, at a faster and faster rate, or at a slower and slower rate? Support your conclusion.
......!!!!!!!!...................................
RESPONSE --> It changes at a slower and slower rate. Every -10cm it took longer the next time to reach the next -10cm. The change of y divided by the change of time would give a decreasing rate. -10cm/24sec = -.83 then -10/36sec = -.71 confidence assessment: 2

16:37:55 ** If you time the water at equal time intervals you should find that the depth changes by less and less with each new interval. If you timed the depth at equal intervals of depth you should find that each interval takes longer than the one before it. } Either way you would conclude that water flows from the hole at a decreasing rate. The reason is that as the water depth decreases the pressure forcing the water out of the hole decreases. **

RESPONSE --> I understand that the water pushing down made it come out of the hole with more force and quicker. self critique assessment: 3

16:42:07 What does the graph of depth vs. clock time look like? Is it increasing or decreasing? Does the rate of increase or decrease speed up or slow down? Does your graph intercept the y axis? Does it intercept the x axis? How would you describe its overall shape?
......!!!!!!!!...................................
RESPONSE --> A curved line decreasing. The line starts off fairly steep, but then begins to level out as it becomes closing to the x axis. The rate of decrease slows down as time goes on. It doesn't intercept the x-axis because that would mean negative water going out of the tube which doesn't happen. confidence assessment: 2

16:42:41 ** The graph will start on the positive y axis and will decrease at a decreasing rate. The shape of the graph is the left-hand side of a parabola that opens upward. The right-hand half of the parabola does not correspond to the flow. The lef-hand half of the parabola, which corresponds to the flow, gets less and less steep with increasing clock time, matching the fact that that the rate of decrease is slowing. At the instant the containers empties, the water will be at the level of the hole. If depth is measured relative to the hole, then at the instant depth will reach zero. The corresponding graph point will lie on the t axis and will correspond to the vertex of the parabola. **
