For a lever of 0.5 m length with a pivot in the centre, an object weighs 5N is seated 0.25 m left side of the pivot. a-How far must the other 10N object be seated from the right side of the pivot in order to balance the lever

The rearrangement of particles in a physical change. hope this

The relationship of both of them

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
