Answer:
The population of the colonies that later became the United States increased steadily in the decades prior to , and including, the American revolution. The first decennial census took place in 1790 . Since that time, the natural increase, i.e, the excess of births over deaths, has been a constant contributor to popular growth. The other factor, immigration, has ranged for negligible to large at various points in the nation's history.
After 1830, immigration began to grow again. Although the birth rate showed a decline , the net population growth rate remained high until after the Civil War. In the decade ending 1870, population growth dropped below 30% for the first time in the nation's history. Substantial immigration kept the population rising at 20% or more for each decade until 1920, when the effect of Word War I reduced it to 14.9% .
The strength of the electric field (E) at the position indicated by the dot can be obtained with the formula: E = F/q where;
F = Force exerted per unit and
q = Positive electric charge at that point.
<h3>What is the Strength of an Electric Field?</h3>
The strength of an electric field, E refers to the force exerted per unit positive charge. It is indicated by the formula: E = F/q. Its SI unit is Newton per Coulomb or Volts per Meter (V/M).
Note that the strength of an electric field is strongest where the lines are close and weakest when the lines are further apart.
The complete question is not provided but the above formula can be used in arriving at the answer.

Just you know what that is but if I’m clearly about that question then I don’t know what to tell you and beside I don’t know the answer too
Electricity, like in electric cars
