Your friend just challenged you to a race. You know in order to beat him, you must run 50 meters within 60 seconds in an eastern direction. What does your average velocity need to be to win the race? (2 points)
.5 meters per second, east
Ob
.83 meters per second, east
1.2 meters per second, east
Od
3000 meters per second, east

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

Ithink the answer is d

C. it comes from the core of the earth.

The correct answer is  ait's a process by which rocks and minerals undergo in their composition^o^
