the answer is A. The aluminum has 0.84 ohms more resistance.
Answer:
2 ohms
Explanation:
Hi there!
Ohm's law states that 
where V is the voltage, I is the current and R is the resistance.
Plug in the given information (I=7.5, V=15) and solve for R
Divide both sides by 7.5 to isolate R
Therefore, the circuit resistance would be 2 ohms.
I hope this helps!

Explanation:
Law 1 states an object at rest , stay at rest and an object in motion stays in motion unless acted on by another force.
Law 2 states that the acceleration of an object depends on its mass and force applied.
Law 3 states every action creates an equal and opposite reaction.
