I think it’s c because the other ones are just options not facts
The density is determined on the steepness of the slope. The greater the density is bases upon the steepest slope. To conclude, I'd say Line A has the steepest slope therefore has the greatest density.
<u>F = M A </u> (Newton's #2)
Force = (0.15 kg) (12 m/s²)
Force = (0.15 · 12) (kg·m/s²)
<em>Force = 1.8 Newtons</em>
Answer: Blood primarily moves in the veins by the rhythmic movement of smooth muscle in the vessel wall and by the action of the skeletal muscle as the body moves. Because most veins must move blood against the pull of gravity, blood is prevented from flowing backward in the veins by one-way valves.
Good luck !
