Question
1. The length and width of a living room is 5.5m and 4.8m with an uncertainty of 0.1m in each measurement. The perimeter of the room with associated uncertainty using the "propagation of error rules" as presented in the pre-lab notes is:
a. 20.6 +/- 0.8m
b. 20.6 +/- 0.4m
c. 20.6+/- 0.1m
d. 20.6 +/- 0.2m
e. 20.6 +/- 0.6m
2. A cylindical glass bottle has a radius of 4.5 cm and a height of 30.0 cm. The uncertainty in both measurements is 0.1cm. Find the volume (v= pi r squared (h)) of the bottle with its associated uncertainty using the "highest and lowest" method of estimation of uncertainty as presented in the pre-lab notes.
a. 1908.518 +/- 0.001cm^3
b.1900 +/- 90cm^3
c. 1900 +/- 80 cm^3
d. 1908.518 +/- 91.188cm^3
e.1908 +/- 0.1cm^3
