Instead of thinking about one field changing in response to the change of the other, it is more correct to say that. whenever the magnetic field is changing, so is the electric field, and vice versa.The way these fields change is governed by Maxwell's equations.This way, we do not arrive at the confusion OP has.nstead of thinking about one field changing in response to the change of the other, it is more correct to say that. whenever the magnetic field is changing, so is the electric field, and vice versa.
Gross profit = net sales â cost of goods sold. Gross profit percentage = [(net sales â cost of goods sold)/net sales] Ã 100%.
Note that the gross profit is the percentage of the adjusted revenue to cover taxes and a net profit of 9%. Tax is 23% of gross. Therefore gross = (.23g + .09); therefore .77g = .09; then g=.09/.77 = .1169 or Gross Profit (sometimes referred to as Ordinary Income) = 11.69% of adjusted revenue.
