Question 18 (1 point) A gun is fired 5,425 km away from a mountain. The sound of the shot travels 367.
How long will it take for the person who fired the gun to hear the echo? Round to
the nearest whole number.

One splits the atoms and molecules  the other combines them

Ohm's law tells you that i = v/r where v is equivalent voltage and r is equivalent resistance of the circuit
since all circuits have the same voltage, your question is really asking which circuit has the lowest total resistance, since the lower the resistance, the higher the current
circuit a has a resistance of 5 ohms; circuit c is in series so has a resistance of 10 ohms; circuit b is in parallel and therefore has a resistance of 2.5 ohms (review your notes on adding resistances in parallel and series); therefore b has the highest current
