BRAINLIEST+10PTS: does ozone absorb just harmful UV rays? Or just a random portion of UV?

Physics

Answer:As sunlight passes through the atmosphere, all UVC and most UVB is absorbed by ozone, water vapour, oxygen and carbon dioxide. UVA is not filtered as significantly by the atmosphere. Is there a connection between ozone depletion and UV radiation? Ozone is a particularly effective absorber of UV radiation.

Answer:

The ozone layer absorbs a random portion of UV rays.

Explanation:

The ozone layer absorbs a random portion of UV rays because the only way UV rays could be harmful to your skin is if there is too much of it. All UV rays are bad, but the only reason you get harmed from them is if you absorb an excessive amount of them.

The average density of living matter on earthâs land areas is 0.10 g/cm2 . what mass of living matter in kilograms would occupy
Margaret [11]
<span>Density is a value for mass, such as kg, divided by a value for volume or area. Density is a physical property of a substance that represents the mass of a certain substance per unit volume or unit area. From the problem statement, we are given the density of the living matter in a particular area and the area. To calculate mass, we simply multiply the area to the density. However, we should remember that the units should be homogeneous or the same and if not, we convert.

Mass = density x area
Mass = 0.10 g / cm^2 (0.125 ha) ( 1x10^8 cm^2 / 1 ha )
Mass = 1250000 g or 1250 kg</span>

Which of the following is the volume of the shaded in Of the sphere?
marysya [2.9K]

Answer:

The correct option is;

πR³(2/3 + (1/3)cos³θ - cosθ)

Explanation:

The volume of a segment of a sphere is given by the relation;

V = \pi \cdot h^2 \cdot \left (R - \dfrac{h}{3} \right)

We note that h = R - R·cos(θ)

Therefore by substituting the value of h in the equation of a segment of a sphere, we have;

V = \pi \cdot \left (R - R\cdot cos(\theta) \right ) ^2 \cdot \left (R - \dfrac{\left (R - R\cdot cos(\theta) \right )}{3} \right)

Which gives;

\dfrac{R^3\cdot \pi \cdot cos^3 (\theta) -3 \cdot R^3 \cdot\pi \cdot cos (\theta) +  2 \cdot R^3 \cdot \pi}{3}

R^3\cdot \pi \cdot  \left (\dfrac{cos^3 (\theta) -3 \cdot cos (\theta) +  2 }{3} \right )

R^3\cdot \pi \cdot  \left (\dfrac{cos^3 (\theta) +  2 }{3} -  cos (\theta)  \right )

R^3\cdot \pi \cdot  \left (\dfrac{cos^3 (\theta) }{3} + \dfrac{2}{3} -  cos (\theta)  \right )

Therefore, the correct option is πR³(2/3 + (1/3)cos³θ - cosθ).
