Question

Which of the following measurements are in their most appropriate form:

(A) 7.425 ± 3.2 m
(B) 9,876,543,210 ± 21,648 years
(C) 6.541 ×103 ± 43 seconds
(D) 2.222 ×10−3 ± 2.2 ×10-5 radians
(E) (0.00 ± 0.04) kg

Answer 1

Answer:

(E) (0.00 + or - 0.04) kg

Step-by-step explanation:

(0.00 + or - 0.04) kg gives the most appropriate form of mass measurement.

Lower bound of the mass = 0.00 - 0.04 = -0.04 kg

Upper bound of the mass = 0.00 + 0.04 = 0.04 kg

The mass lies between -0.04 kg and 0.04 kg
