Question

The uncertainty in a measurement is typically found in te last digit of the number. For example, in the measurement 1.2 inches, the uncertainty lies in the tenths place (or the 0.1 place). For each of the following measurements, indicate the decimal place in which the uncertainty lies.

a.) 2.730 meters

b.) 0.4006 pounds

c.) 330. feet

d.) 2345 miles

e.) 330 feet

f.) 5.0 x 10⁴ kilograms

Answer 1

The uncertainty in a measurement is typically found in te last digit of the number

a. 2.730 meters. Here uncertainity at 1000 th place. ie at 0.001 place.

b. 0.4006 pounds . Here uncertainity is at 10000 th place ie at 0.0001 place

c. 330. feet Here uncertainity is at tenth place decimal 0.1

d. 2345 miles here uncertainity is at ones place

e. 330 feet . Here uncertainity is at ones place.

f 5.0* 10⁴ Kg = here uncertainity is at 10000 th place.= 0.0001 place
