Jake throws a rock downward from his deck at time t=0t=0t, equals, 0 and it lands in his yard below. Which of the following graphs best shows the velocity vvv of the rock until it hits the ground?

Ibelieve the correct answer would be c.

Show him another sport or something

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
