Prepararam-se duas soluções aquosas de açúcar (sacarose) com a seguinte composição: - solução A: 13,0 g de açúcar em 200 cm3 de solução; - solução B: 8,0 g de açúcar em 100 cm3 de solução. Diz, justificando, qual é a solução mais doce. Nota: para justificar calcula a concentração mássica de cada uma das soluções e coloca aqui os valores obtidos.

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

Answerthe force between the charges will be  f/9 (one-ninth of force f)explanationcoulomb's law relates the magnitudes  two point charges q₁ and q₂, the distance, r, between the charges, and the electrostatic force, f, between the two charges:     k represents coulomb's constant, k = 8.99×10⁹ n·m²/c².note that if we have r = 3r, then
