Question

question 5 (1 point) listen the force on an object is measured to be 0.423 n with an uncertainty of 0.67 n. the correctly rounded off uncertainty is n and the correctly rounded off value is n. hide hint for question 5 round uncertainty to one significant figure. round value to same decimal position as that single significant figure. don’t use scientific notation.

Explanation:

Step1: Round the uncertainty

The uncertainty is 0.67 N. Rounding to one - significant figure, since 6 is greater than 5, we round up. So 0.67 rounds to 0.7 N.

Step2: Round the measured value

The measured value is 0.423 N. Since the uncertainty is rounded to the tenths place, we round the measured value to the tenths place as well. 0.423 rounds to 0.4 N.

Answer:

0.7; 0.4
