Answer:

the answer is biomass or biopopulation

Explanation:

when someone talks about a population, they are talking specifically of humans living within a set area. If someone is talking about the organisms living in an area, they are speaking of living things within a set area. bio- meaning life and mass- meaning density of. density is not always speaking of weight. it could also mean how full. biomass means the amount of living organisms within a set area.

A circle has a diameter

torisob [31]

The circumference of circle is 20.096 units

<em><u>Solution:</u></em>

Given that circle has a diameter with endpoints at (10, 8) and (5, 4)

To get the diameter, find the distance between the end points

<em><u>The distance between two points is given by formula;</u></em>

$d=\sqrt{\left(x_{2}-x_{1}\right)^{2}+\left(y_{2}-y_{1}\right)^{2}}$

Here the points are (10, 8) and (5, 4)

$(x_1, y_1) = (10, 8)\\\\(x_2, y_2) = (5, 4)$

Substituting the values we get,

$\begin{aligned}&d=\sqrt{(5-10)^{2}+(4-8)^{2}}\\\\&d=\sqrt{(-5)^{2}+(-4)^{2}}=\sqrt{25+16}=\sqrt{41}\end{aligned}$

$d = \sqrt{41} = 6.4$

Thus the diameter is 6.4 units

<em><u>The circumference of the circle is given by formula:</u></em>

$c = \pi d$

Where "d" is the diameter of circle

$c = 3.14 \times 6.4 = 20.096$

Thus circumference of circle is 20.096 units

Alona [7]

Answer:

$T = 3.23 \times 10^{-83}$

Explanation:

thickness of aerosol layer is 2.5 km

zenith angle is 40 degree

we know that

$\tau = \epsilon_{ext} . h$

where

$\epsilon_{ext} = N.\sigma_{ext}$

$\epsilon_{ext}$ is extinction coefficient

$\sigma_{ext}$ extiction cross section

N = Concentration

$\sigma_{ext} = (2.5 + 0.45)\times 10^{-12} m^2$

$= 2.95 \times 10^{-12} m^2$

$\epsilon_{ext} = 2\times 10^7 \times 2.95 \times 10^{-12} m^2 \times m^{-3}$

$= 5.9 \times 10^{-5} m^{1}$

$\tau = 5.9 \times 10^{-5} m^{-1} \times 2.5\times 10^3 m$

$= 14.75\times 10^{-2}$

transimiitance $T = e^{\frac{-\tau}{\mu}}$

$T = e^{\frac{- 14.75 \times 10^{-2}}{cos 40}}$

$T = 3.23 \times 10^{-83}$
