What motivates countries to join regional trade blocs? removing barriers to trade protects from influence of foreign markets increasing tariffs adds to the national gdp eliminating barriers to trade benefits the economies of member nations expanding trade relationships reduces cultural diffusion

The correct answer is: "eliminating barriers to trade benefits the economies of member nations".

Regional trade blocks are intergovernment treaties through which several countries agree to eliminate trade barriers among its members, so that they can enjoy free trade within the region. Moreover, they establish a joint external trade policy, setting tariffs and other trade barriers to cope with competitors from outside the block.

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.
