We'll make the following conventions for our units of measurement:•Let 'cm' stand for centimeters as measured with the full-sized ruler.
•Let 'cm_s' stand for centimeters as measured with the singly-reduced ruler.
•Let 'cm_d' stand for centimeters as measured with the doubly-reduced ruler.
•Let 'cm_t' stand for centimeters as measured with the triply-reduced ruler.
Answer the following:
Which is longer, one cm_d or one cm_s?
one cm_s

It is likely that your answers to the following will be in the form of decimal numbers. Give your results to three significant figures:
How many cm_t make a cm?
3.8
****
#$&*
How many cm_t would a measurement of 3 cm be?
11.4
****
#$&*
How many cm would a measurement of 13 cm_t be?
3.42

Does it depend on where on the ruler the measurement is made?
It shouldnt but based on how they may be printed it may.

How many cm_s make a cm_t?
.4

How many cm_s would a measurement of 5 cm_d be?

How many cm_d would a measurement of 11 cm_t be?

Does it depend on where on the ruler the measurement is made?

Now answer the following questions about significant figures, including a brief but concise explanation.
Do you think all the significant figures in your result are appropriate? Explain.
Yes, because they make my aswers the most accurate to the measurment.

#$&*
To how many significant figures are you pretty sure you could answer these questions. Explain.
It depends on how large the measurments are but I would say i could be accurate to 2 sig figs to the right of the decimal
****
#$&*
What is the smallest number of significant figures for which the last figure would be completely meaningless? Explain
I'm not sure I understand this question but i guess 3 sig figs to the right of the decimal because it would not be with significant accuracy.
