Problem Set 5C: A child and sled with a combined mass of 52.1 kg slide down a frictionless hill. Assuming that they
start at rest (v; = 0) and they are on Earth (g = 9.81m), calculate the initial height (hi) if their final speed (vf) is
12.3 m/s at the bottom of the hill (hj = 0).
The calculated answer is
Please do not include units and
round answer to ONE place after the decimal.

It indicates no change in temperature and the process of matter changing its state

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

Well i am not very good at this but  i would be guessing 1hope i
