Answer:1.With weathering, rock is disintegrated into smaller pieces. Once these sediments are separated from the rocks, erosion is the process that moves the sediments away from it's original position. The four forces of erosion are water, wind, glaciers, and gravity. Water is responsible for most erosion. 2.Increasing the surface area of a reactant increases the frequency of collisions and increases the reaction rate. Several smaller particles have more surface area than one large particle. The more surface area that is available for particles to collide, the faster the reaction will occur.

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

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

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

When the price of oil drops this usually means that OPEC has?

Nikolay [14]

When the price of oil drops this usually means that OPEC or a major state within OPEC like Saudi Arabia, or Venezuela has increased the supply of oil leading to a drop in price. This is the current policy of the Saudi Government which has led to a drastic decline in oil prices over the last 3 to 4 months.
