Question

question 4 (1 point) saved listen the mass of an object is measured to be 127 g with an uncertainty of 12 g. the correctly rounded off uncertainty is 10 g and the correctly rounded off value is 130 g. hide hint for question 4 round uncertainty to one significant figure. round value to same decimal position as that single significant figure. dont use scientific notation.

Explanation:

Step1: Round uncertainty

The uncertainty is 12 g. Rounding to one - significant figure, since 2 < 5, we round 12 to 10.

Step2: Round object mass

The mass of the object is 127 g. The uncertainty is rounded to the tens place (10), so we round 127 to the tens place. Since 7 ≥ 5, 127 rounds to 130.

Answer:

The correctly rounded - off uncertainty is 10 g and the correctly rounded - off value is 130 g.
