Answer:
The velocity of the blood in the thinner arteries is 0.1 times that of the thicker artery.
Explanation:
To find the velocity of the blood we need to use the continuity equation:
(1)
<u>Where</u>:
n: is the number of branches
A: is the cross-sectional area
v: is the velocity
For artery 1, we have:
n₁ = 1, A₁ = 1 cm², v₁ = v
For the 20 arteries (2), we have:
n₂ = 20, A₂ = 0.5 cm², v₂ =?
By using equation (1):
Therefore, the velocity of the blood in the thinner arteries is 0.1 times that of the thicker artery.

Answer:
The independent variable is what you, the scientist, changes, and it causes the dependent variable to change.
Explanation:
So the equation used in this problem is ΔX=V0*T+1/2AT^2 the X is the distance, v0 is initial velocity, T is time, and a is acceleration. So when we plug these values it we get: 108= 0•T+1/2•3•T^2,the 0•t disappears, and the 1/2•3 gets us 1.5, so we have 108=1.5T^2, then we divide 108 by 1.5 which gets us 72=t^2, and we then take the square root and get 8.49=T so the answer is 8.49 seconds.

Can't tell if this is a real question or not but....
Reality shifting is based around this idea, but instead of letting it happen freely, the most precise details of your experience are planned by you! It's like incorporating a daydream into your subconscious. Reality shifting is a complex process, but anyone is able to do it.
