   4.7×10⁻³ μF

Step-by-step explanation:

The "p" in "pF" stands for the SI prefix "pico", which means 10⁻¹². The μ in μF stands for "micro", which means 10⁻⁶. So ...

  4700 pF = 4700×10⁻¹² F = 4.7×10⁻⁹ F = 4.7×10⁻³ μF

the total estimated nappy use.=10,500,000

step-by-step explanation:

given that on an average the average baby uses 3528 napkins.

in a particular year 2014, the number of births were 299697 in new south wales.

rounding off the number of births to the nearest hundred thousand we have

no of birtsh = 300000

also rounding off the average usage to nearst thousand we get

average use of a baby = 3500

hence total number of nappy estimated to be used = 3500x300000

= 10,500,000

answer is 10,500,000 nappies
