1. What is the difference between 401 k) matching and profit sharing ?

In a 401(k) that allows an employer match – employees can receive employer contributions as well as make their own contributions. ... But in a profit-sharing plan, only employer contributions are permitted (i.e. an employee cannot make any contributions)

Explanation:

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.

i'd have to with d.
