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

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

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

Answer:

For a geographer Map is the most important tool

Explanation:

Apart from the above geographers rely on various tools and techniques which are both Qualitative and Quantitative. Such as the Primary and secondary sources of data like surveys, questionnaires, and journals, etc. Apart from this use of satellite data to generate a comparative analysis of objects and there processing in terms of software i.e the GIS, GPS that store and breaks the data into an understandable format. Use of mental maps to understand the spatial construct of humans and the use of Aerial photography to help the geographers do an in-depth analysis of the landscape. Tools like the map which is again divided into various types such as the topological maps, hydrological maps, physiological, political and many more are essential tools of any geographer.
