Question
Please answer the following, thank you!
of precision is high but the accuracy is low because of the
nature of the measuring instrument used and of the object measured. Precision is also limited
by the skill of the worker in making estimates or in using the measuring instruments (like
viewing the meterstick at the same angle or placing the zero reading at the same point of the
object).
EXERCISES
1. How will you find the percent uncertainty in the following:
a. 100 ± 2 cm
b. 50 ± 0.5 cm
C. 525 ±5 cm
What is the other way of writing the value of the measurement?
2. The value of a measurement is between 60 cm and 80 cm. What is the percent uncertainty of
the measurement? How will you write the value of the measurement?
3. The correct value of a measurement is between 150 cm and 170 cm. Find the percent
uncertainty of the measurement. How will you write the value of the measurement?
Scientific Notation
Small numbers and large numbers are not easy to handle because we are limited by the system
of units that we are able to use. Since we use the meter as the standard unit of length, we will get
into trouble writing the size of the universe as 100,000,000,000,000,000,000,000,000 meters
