Two objects of different mass have equal, non-zero kinetic energies. which object has the greater momentum?
the heavier object, the lighter object, or do they have the same momentum? the internet says the heavier object. give an explanation also!

Momentum= mass*velocity thus if you keep velocity constant an increase in mass increases momentum so the heavier object (assuming constant gravity) has a higher momentum than a lighter object 

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
