¿Cual es la fuerza de atracción entre Martes y Júpiter si la distancia entre ellas es de 411,394,028.86km? Masa de Marte:
6.93 x 10^23kg

Masa de Júpiter:
1.898 x 10^27kg

The answer is orbit around nucleus

That depends on what kind of environ meant it is in  in space it has the same force that was applied when the velocity was gained

Inner peace.. jk it's  a stable electron configuration

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
