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.
Density = mass divided by volume so if you use that formula Liquid A turns out to be a higher density so it flows slower.

We know that speed is a scalar unit while velocity is a vector. The signs are mostly concerned with the magnitude that the car should travel in, the direction is not as important.
Hope I helped :)
<em>Inertia</em> is the property of all matter by which it tends to remain in constant, uniform motion until it's acted on by an external force.
