Your work on rubber band calibration has been received. Scroll down through the document to see any comments I might have inserted, and my final comment at the end.
1,8.5; 1, 8.0; 1,8.3; 1,8.5
7.51, 7.00, 7.32, 7.50
I subtracted the second number in the set by the first number to get the actual measurement. However, I am completing this lab away from home and do not have a reduced copy of the rulers because it was not listed in the materials needed at the top. I can't wait until I get back home to do this because the lab would be late. I used the same regular ruler as I did in the last lab for this lab. I feel that it is accurate to one tenth.
This ruler is marked with cm and 1/2 cm therefore that is mt estimate of uncertainty.
1,8.5; 1, 8.0; 1,8.3; 1,8.5

The uncertainty is the same as above.
8.00, 7.00, 7.50, 7.71
The second line indicates that these results were from the weight of two dominoes.

I ran out of dominos before the rubber bands stretched to 30 percent of their original length.

End
The first four columns indicate the length each rubberband stretched in centimeters. The fifth line indicates the downward force by each additional domino. The lengtg is measured in centimeters and the force is measured in Newtons.

They are both close together so I think either one would work. I think it would be +-.03 N by comparing this to the results above.
By +- .05 based on the data above.
Your work on this experiment will be compiled and you will receive a more extensive analysis and a reply after the due date. At first glance it looks good.
