3m to the power of 2= 222<br> What is the value of m?
Alecsey [184]

Answer:

if it is 3m^2 then √74        if you meant (3m)^2 it is √74/3

Step-by-step explanation:

if the first then you divide 3 from both sides thus getting m^2= 74, and you get m=√74, if second then you get 9m^2 and you divide 9 from both sides and get m^2 = 2.4(8) and you square that to get √74/3

The velocity v of blood that flows in a blood vessel with radius r and length ℓ at a distance r from the central axis is v(r) =
pogonyaev
v(r)=4P\eta\ell(R^2-r^2)

(assuming R is the radius of the vessel, and that 0\le r\le R)

The average velocity of the blood is given by

\displaystyle\frac1{R-0}\int_{r=0}^{r=R}v(r)\,\mathrm dr
=\displaystyle\frac{4P\eta\ell}R\int_{r=0}^{r=R}(R^2-r^2)\,\mathrm dr
=\dfrac{4P\eta\ell}R\left(\dfrac23R^3\right)
=\dfrac{8P\eta\ell}3R^2
