The human circulatory system consists of a complex branching pipe network ranging in diameter from

Stels [109]

Answer: the average velocity decreases

Explanation:

From the provided data we have:

Vessel avg. diameter[mm] number

Aorta 25.0 1

Arteries 4.0 159

Arteioles 0.06 1.4*10^7

Capillaries 0.012 2.9*10^9

from the information, let $\hat{m}$ be the mass flow rate, $\rho$ is density, n number of vessels, and A is the cross-section area for each vessel

the flow rate is constant so it is equal for all vessels,

The average velocity is related to the flow rate by:

$\hat{m} = v* \rho * A * n$

we clear the side where v is in:

$v = \frac{\hat{m}}{\rho A n}$

area is π*R^2 where R is the average radius of the vessel (diameter/2)

we get:

$v = \frac{\hat{m}}{\rho \pi R^2 n}$

you can directly see in the last equation that if we go from the aorta to the capillaries, the number of vessels is going to increase ( n will increase and R is going to decrease ) . From the table, R is significantly smaller in magnitude orders than n, therefore, it wont impact the results as much as n. On the other hand, n will change from 1 to 2.9 giga vessels which will dramatically reduce the average blood velocity

Based on the pattern, what are the next two terms of the sequence? 9,94,916,964,9256,... A. 91024,94096 B. 9260,91028 C. 9260,92

Hatshy [7]

Answer:

The answer is "Option A".

Explanation:

Series:

$9, 94, 916, 964, 9256, ........$

Solving the above series:

$\to 9\\ \to 9(4) =94\\\to 9 (4^2) = 9(16) =916\\\to 9 (4^3) = 9(64) =964\\\to 9 (4^4) = 9(256) =9256\\\to 9 (4^5) = 9(1024) =91024\\\to 9 (4^6) = 9(4096) =94096\\$

So, the series is: $9, 94, 916, 964, 9256, 91024, 94096, .................$
