Answer:
brightness that we observe from a star is related to the energy produced and the distance to the Earth
Explanation:
In stars, the color that we observe is directly related to the temperature of the star by the y of the Wien displacement.
λ_{max} T = 2,898 10³
the brightness that we observe from a star is related to the energy produced and the distance to the Earth
Answer: 28°
Explanation:
Snell's law n₁sinθ₁ = n₂sinθ₂
1.33sin32 = 1.5sinθ₂
θ₂ =28°
The three parts of the Earth are Atmosphere, Hydrosphere and Lithosphere.
Atmosphere is the blanket of air that surrounds the earth. It is densest close to the surface and thins out as one moves higher. Atmosphere of Earth contains mainly Nitrogen, followed by Oxygen and small amounts of water vapor, Carbondioxide and other gases.
Lithosphere is the outer most part of the earth's surface. The Earth's crust and the mantle form Lithosphere.
Hydrosphere is the part of the Earth that has water. The Oceans, seas, rivers, lakes and other water bodies constitute the Hydrosphere.
Stratosphere, Mesosphere and Ionosphere are different layers of atmosphere.
Hence, for the study of the Earth, one needs to consider earth to be made of three parts- atmosphere, Lithosphere and Hydrosphere.
It would be the temperature of her hand and also because it is going through the process of the water cycle it is changing from a solid to a liquid
To develop this problem it is necessary to apply the concepts performed to the absolute pressure based on the reference pressure (atmospheric) and the pressure that is generated due to the height of the column of the measured liquid.
In mathematical terms the previous concept can be expressed as
Where
Atmospheric Pressure
Density
g = Gravitational acceleration
h = Height
Our values are given as
g = 9.8m/s
Replacing we have then that
Therefore the absolute pressure in the test section is 99.9019kPa
