Answer:
b. A voltage causes electric charges to move from lower to a higher potential.
Explanation:
As we know, current flows from high voltage to low voltage and the electric charge flows opposite to the direction of the current. That is why we can say that the electric charge flows from low voltage to high voltage.
Resistance does not cause the electron to flow from low voltage to high voltage.
Therefore the answer is b.

Answer:
sphere moves with a constant terminal velocity.
Explanation:
mass of sphere, m = 0.5 kg
velocity downward, v = 8 m/s
buoyant force = 4 N
fluid friction force = 4 N
Weight of the sphere is acting downward.
W = mg = 0.5 x 10 = 5 N
When the object is immersed in a fluid and it moves in the fluid with constant velocity, it means the net force acting on the object is zero, and the object attains a terminal velocity.
