(13) [CT] A table is exactly 75 cm tall. (a) Which measurement is the most precise? (b) Which measurement is NOT accurate? A) ℎ = 75 ± 1 ?? B) ℎ = 76 ± 1 ?? C) ℎ = 75.3 ± 0.1 ?? D) ℎ = 60 ± 20 ??
Homework Answers
- An accurate result would be exactly near the actual value, or equal to the actual value.
- Precise result need not be accurate. The closeness of all the taken attempts.
a) Options A and B are not close compared to option C. In option C the two possible results are described as 75.3, 75.2, 75.4 .All are just in a difference of 0.1. So option C is most precise.
b) option d value 60 very far away from the actual result of 75 CM, so it can be said... NOT accurate.
Option C..... Most precise.
Option D..... Not accurate

part 1 Does a chemical or physical change force the bullet out of a gun? Would the smoke coming out of the end of the gun most likely a homogeneous or heterogeneous mixture? Explain your answers. Part 2 Scientific facts are measurements. They are not changeable, nor are they subject to interpretation. However, with any measurement, in science, there is a certain amount of uncertainty. This uncertainty is made up in two basic ideas: accuracy and precision. In the real...
