Your solution, attempt at solution.

If you are unable to attempt a solution, give a

phrase-by-phrase interpretation of the problem along

with a statement of what you do or do not understand

about it. This response should be given, based on

the work you did in completing the assignment, before

you look at the given solution.

Question: `qQuery Introduction to General Themes;

Examples (no summary needed) What were some of the

things in this introduction that you found

interesting or surprising?

YYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYY

Your solution:

My dad use to do these experiments with us as kids, so i was interesting to see them in a class.

Very good. My kids weren't interested, but my grandson is; hopefully they'll be profitable to him.

Question: `qQuery 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.

YYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYY

Your solution:

Slower and slower rate

As the water flows out the pressure on the water decreases inside the bottle.

confidence rating:

^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

.............................................

Given Solution:

** 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.

Question: `qWhat 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?

YYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYY

Your solution:

The points would start getting closer and closer, swooping downward from the highest water point.

Decreasing

Slows down

Starts at Y ends at x

Half of parabola opening up

confidence rating:

^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

.............................................

Given Solution:

** 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. **
