ANSWER:Solution:
Step 1of 5:
The shape of a bacterium is approximated by a cylinder of radius r and h capped on each by a hemisphere. The volume and surface area of the bacterium is given by
V =
S = (h + 2r)
Where r = 0.8and h = 1.90.1. Here the rate R at which the chemical is absorbed to the bacterium is R = c (S/V), where c is a constant of proportionality.
We have to find
- The estimate of S, and the relative uncertainty in the estimate.
- The estimate of V, and the relative uncertainty in the estimate.
- The estimate of R,and the relative uncertainty in the estimate.
- Whether the relative uncertainty of R depend on c.
