The 3 kinds of blood vessels are: Ateries, , and veins.

a
ventricles
b
chambers
c
valves
d
capillaries

D, capillaries.

Explanation:

Basically there's three types of vessels. The arteries are are the blood vessels that deliver oxygen-rich blood from the heart to the tissues of the body. There is also the veins, which are blood vessels that carry blood low in oxygen from the body back to the heart for reoxygenation. Then the capillaries, they are very tiny blood vessels, basically so f-cking small that a single red blood cell can barely fit through the thing. They help to connect your arteries and veins in addition to facilitating the exchange of certain elements between your blood and tissues.

i can ! i just need to know what the paragraph is! : p

(newtons first law)

conservation of momentum law states :

momentum before collision = momentum after collision

momentum p (kg-m/s)= mass * velocity

say moving car=1 000 kg, velocity = 10 m/s then p = 1 000*10= 10 000 kg-m/s

say still car = 2 000 kg, velocity = 0 m/s then p = 2 000* 0 = 0 kg-m/s

total momentum prior to collision = 10 000 + 0 = 10 000 kg-m/s

momentum after collision = 10 000 kg-m/s

mass now = 1 000 kg+2 000 kg = 3 000 kg

10 000 = 3 000 kg* velocity m/s

10 000/3 000 = velocity

3.33 m/s = velocity after collision

an impulse is a force applied over time , momentum is exclusive of external forces and a perfect collision is implied
