Ao conferir uma resolução feita por um colega de classe, pedro avaliou que ela não estava correta. leia o enunciado da questão e a resolução apresentada pelo colega de pedro e verifique quem está correto. caso a resolução esteja errada, qual é a resposta correta ?
questão: determine a massa de um corpo(em kg) que após sofrer a ação de duas forças com módulos 10 n e 12 n, com mesma direção e sentidos opostos, adquire aceleração de 2 m/s².
resolução: r = ma => 22 = m.2 => m= 11 kg

Honestly "global warming" may be a slight possiblity, however they called it "climate change" because its not real, in fact we had one of our coldest days here not too long ago, and the "issues" with this subject is a blindfold for actual problems.

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
