Bella investigated forces by sliding blocks made of different materials down a ramp. She recorded the time it took for each block to reach the bottom of the ramp in this table. ( will give brainliest if you help)

No because scientist are still changing there mines today so they are not correct to this day

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

Ai think hope that
