shown. Or, if the situation is ambiguous, write “ambiguous.”
a) 4325 kg m/s2
b) 4.0000011 V
c) 0.003330 m/s
d) 4000 C
e) 8.900 x 107 A
2) (10 points) Write each of the following quantities and their uncertainties in
“standard format”
a) 7230 ± 670 kg
b) 8.145 ± 0.0622 kg
c) 42,456,123 m ± 36 km
d) 412 cm ± 36 cm
e) 0.00000821567 ± 0.0000005641 m (use scientific notation)
3) (4 Points) Do the following two measurements agree or disagree? Show your work
and explain your reasoning.
M1 = 3.01 ± 0.02 kg
M2 = 3.10 ± 0.05 kg
Explanation / Answer
Q.1 a) one
b)one
c)one
d)ambigous
e)ambigous
Q.2
a) 7230 ± 670 kg = ( 7.23 +- 0.67) x 10^ 3
b) 8.145 ± 0.0622 kg= ( 8.145 +- 0.06)
c) 42,456,123 m ± 36 km = (4.2 x 10^4 + - 3.6 ) x 10^4
d) 412 cm ± 36 cm= ( 4.12 x 10^ 2 +- 0.36 x 10^2) = ( 4.12 +- 0.36) x 10^2
e) 0.00000821567 ± 0.0000005641 m (use scientific notation)= ( 8.2 x 10^-6 +- 0.56 x 10^-6) = ( 8.2 +- 0.56) x 10^-6
