You measure the following quantities: A = (1.0 0.4) m B = (2.0 0.2) m
Question:
You measure the following quantities:
A = (1.0 ± 0.4) m
B = (2.0 ± 0.2) m
C = (2.0 ± 0.5) m s−1
D = (0.20 ± 0.01) s
Calculate the result and its uncertainty for each of the following expressions. You may express your uncertainty either as an absolute value or as a percentage.
a. A + B
b. B − A
c. C × D
d. B/D
e. A2
f. 2 × A
g. The square root of (A × B). (Recall that the square root of x can be written as x½.)
