How does one get 8.0 a? the answer is d

I don't know why the answer is D , because I can't see the list of choices.

The only way to get 8.0 Amps is by making a serious mistake.

The current in the second picture is 4.0 Amps.

If the resistors are identical, then the effective resistance of

two resistors in parallel is 1/2 the resistance of each one.

The resistance in the second picture is 1/2 the resistance

in the first picture.

Current = (voltage) / (resistance)

Cutting the resistance in half causes the current to double.

If the current was 2.0 Amps in the first picture, it's 4.0 Amps

in the second picture.

i think it’s a. this is because if they measured the mass of something with a mass of 150g, then their final answer would have to be approximately 150g. though all of their answers are almost 150, rosa and tran have the closest answers (or the exact answer) to the accurate one.
