What was the primary cause of the london fog of 1952? a. global warming trapped hot air from blast furnaces in the lower regions of the atmosphere. b. cold air led to heavy use of coal, and the smoke from the coal fires was trapped close to the ground by a temperature inversion. c. effluents from steel factories raised the temperature of the thames river, producing increased water vapor that condensed as soon as it contacted the air. d. unusually strong winds pushed air up the slopes of nearby mountains, where it condensed into fog and was pushed back to the ground by a temperature inversion.

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.

answer; i believe the correct answer is (8) eight.
