What are the roles played by active population in the development of the country??​

active population raises a number of difficult practical problems: (a) When is ... developing countries, however, the definition is much wider and the persons ... lity and migration trends, on the other hand, will play an important role.

Explanation:

He desired that the country’s population must not exceed beyond certain level. Sir William Petty presented an optimistic outlook on population growth.

well, paralell is parallel. i am providing links to .

hope this !

a series circuit is one with all the loads in a row. there is only one path for the electricity to flow. if this circuit was a string of light bulbs, and one blew out, the remaining bulbs would turn off.

unlike in series circuits, a charge in a parallel circuit encounters a single voltage drop during its path through the external circuit. the current through a given branch can be predicted using the ohm's law equation and the voltage drop across the resistor and the resistance of the resistor.

a parallel circuit has certain characteristics and basic rules: a parallel circuit has two or more paths for current to flow through. voltage is the same across each component of the parallel circuit.

add the answer choices and i'll give you the answer
