A cyclist leaves home and rides do you east for a distance of 45 KM she returns home on the same bike path if the entire trip takes 4H what is her average speed what is her displacement

10 neutrons is the answer

No bc a lot of things r still theories n unproven

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
