Two charged spheres (q1= +2.0 C and q2=-3 C) are located 0.05 m apart.
Calculate the electrostatic force between them, and state whether it is attractive or
repulsive

the correct answer is 5 6 and 7

linear pair postulates

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
