A large portion of rain forest was removed and scientists noted a local increase in atmospheric carbon levels. Which best explains this observation?
: 0 Removing the rain forest caused an increase in the levels of cellular respiration, which put more
carbon dioxide into the atmosphere.
O Removing the rain forest decreased the number of plants, which would normally decrease the carbon
dioxide levels in the atmosphere through photosynthesis.
Removing the rain forest caused a decrease in the number of animals, which would normally decrease
the carbon dioxide levels in the atmosphere through cellular respiration.
O Removing the rain forest caused an increase in the number of microorganisms, which put more
carbon dioxide into the atmosphere.

The first one.

Explanation:

Plants use carbon dioxide to release oxygen. Without trees, the carbon dioxide does not get used.

The hydrostatic force on one end of the trough is 54994.464 N

Explanation:

Given;

liquid density, ρ = 810 kg/m³

side of the equilateral triangle, L = 8m

acceleration due to gravity, g =  9.8 m/s²

Hydrostatic force is given as;

H = ρgh

where;

h is the vertical height of the equilateral triangle

Draw a line to bisect upper end of the trough, to the vertex at the bottom, this line is the height of the equilateral triangle.

let the half side of the triangle = x

x = ⁸/₂ = 4m

The half section of the triangle forms a right angled triangle

h² = 8² - 4²

h² = 48

h = √48

h = 6.928m

F = ρgh

F = 810 x 9.8 x 6.928

F = 54994.464 N

Therefore, the hydrostatic force on one end of the trough is 54994.464 N
