Which one of the following distances is the shortest?
a. 0.1 m
b. 1 cm
c. 0.001 km
d. 100 mm?

i think it’s a. this is because if they measured the mass of something with a mass of 150g, then their final answer would have to be approximately 150g. though all of their answers are almost 150, rosa and tran have the closest answers (or the exact answer) to the accurate one.

well clustered together.

points close on a scatter diagram

distance = 150m

displ = root (50 ^2 + 100^2)

root(2500+10000)

root 125000
