Answer:
measurement gives values between 149.01 pound and 150.1 pound
Explanation:
All instruments have limitations in their measurements, have a range, that the maximum value they can measure and has an appreciation that is the minimum variation that can be measured.
The appreciation is determined by several factors, but the most important is the physical properties of the system, for a spring balance the minimum measurable value of the force that creates a spring displacement.
In this case the correct measure is
F = (150 + - 0.1) pound
This measurement gives values between 149.01 pound and 150.1 pound
When measuring weight on a scale that is accurate to the nearest 0.1
pound, the real limits for the weight of 145 pounds is 144.9- 145.1
This is an instrument which is used to measure the weight of objects. There
may be differences in the measurement as a result of air interference and
other factors.
We were told that the accuracy is to the nearest 0.1 pound which means
= 145± 0.1
= (145-0.1) - (145+0.1)
= 144.9 - 145.1
