A)
Note that the smallest division is of 1mm. So, the scale can't read a unit below this. And we know that: 1mm = 10-1cm. So, the correctly rounded off uncertainty=1mm.
Because, the standard deviation = 5.5595063x10-3cm= 5.595063x10-2mm and this can't be read on scale. The least that can be read = 1mm.
---------------------------------
B)
The Mean = 17.04667cm
Note that 1mm = 0.1cm. So, the scale can only read up to one decimal places of centimeter.
And, rounding up to 1 decimal places gives, mean = 17.1cm.

Question 1 (1 point) In a free-fall experiment, a student measures g to be 10.03 m/s2 with an uncertainty of 0.17 m/s2. The standard value is 9.80 m/s2 with an uncertainty of 0.03 m/s2. The measured value does not agree with the standard value within uncertainties. A) True B) False Hide hint for Question 1
