Answer 1

Answer:

Apply the following conversion factors: 1in=2.54cm,1d=86400s,100cm=1m, and 10

9

nm=1m. Then, the rate of hair growth per second is

rate = (

32

1

in/day)

86400s/day

(2.54cm/in)(10

−2

m/cm)(10

9

nm/m)

=9.19nm/s

This means the proteins are assembled at a rate of many layers of atoms each second.
