Hello!
The removal of vegetation causes the desertification and erosion of soil. The roots of the plants that are inside the soil create a sort of net that prevents the material to be dragged by the water from the rain. They also absorb any excess water that can weaken the soil structure. If vegetation is removed from the soil, the nutrients can be dragged by water currents and slowly the desertification will occur.
Have a nice day!
If,
then, with 3x time t, (suppose, new distance is h)
Therefore, new distance h will be 9 times bigger than distance d.
answer: c
Lol what???? i don’t understand
Answer:
1.3636
Explanation:
Write the expression for the refractive index.
n=c/v
c= speed of light in air
v= speed of light in material
=(3×10^8 m/s)/(2.2×10^8 m/s)
=1.3636
Answer:
96w
Explanation:
p=Iv..where v=12 and I=8.0
