Now report and graph your results from the 1b experiment:

• In the first line give the level of squeeze necessary to shorten the air column by 10%, as you determined it in the 1b experiment.

• In the next three lines give the percent change in air column length vs. the level of squeeze, for squeezes of 2, 5 and 8 as you perceived them.

• Graph percent change in air column length vs. level of squeeze (you will have three or perhaps four percents and four levels of squeeze), fit the best straight line you can to your data, and in the fifth line give the slope and vertical intercept of your line.

Your answer (start in the next line):

2, 5, and 8

16.8 cm, 3.5%

16 cm, 7%

16 cm, 7%

Slope: -0.267

x=2

According to the appropriate graph:

• To what height would water rise in an open vertical tube, given a level-10 squeeze?  Answer and explain the basis for your answer. Your answer (start in the next line):

• Maybe 15 cm based off of my graph

I am still confused on this part of the experiment

@&

For a squeeze you perceive as a 2, what was the resulting length of the air column?

For a squeeze you perceive as a 5, what was the resulting length of the air column?

For a squeeze you perceive as n 8, what was the resulting length of the air column?

How much did each of these differ from the original length of the air column?

For each squeeze, what therefore was the percent difference in the length of the air column, relative to the original length?
