Answer:
An asteroid is in circular orbit around the Sun. Its distance from the Sun is 7.3 times the average distance of Earth from the Sun. The period of this asteroid is C : 20 Earth years .
Explanation:
Kepler's law
T² ∝ R³
T = orbital period of the planet
R = semi major axis of the orbit.
Now
( T₁ / T₂ )² = ( R₁ / R₂ )³
T₁ = Earth time period = 1 year
T₂ = Asteroid time period
R₁ = The distance between Earth and Sun
R₂ = The distance between Asteroid and Sun
From the question ,
R₂ = 7.3 R₁
applying on the above equation ,
( T₁ / T₂ )² = ( R₁ / R₂ )³
( 1 / T₂ )² = ( R₁ / 7.3 R₁ )³
( 1 / T₂ )² = ( 1 / 7.3 )³
T₂ = 19.7 year
Hence ,
approximately T₂ = 20 years.
The period of this asteroid is C : 20 Earth years .
Water cycle is effected by pollution, whether it is water pollution or air pollution. Air is polluted by Suspended Particulate Matter and by different harmful gases like Sulphur dioxide etc. These gases react with water vapours in the sky, making the water in the clouds acidic. This acid falls as rain water causing acid rains. This acid falls in ponds, on land, in fields, causing harm to us and to the crops as well as to the fishes or creatures in water. When the water evaporates from ponds, rivers and oceans to make water vapour, the the water in these water bodies becomes more acidic, and again when acid rains occur, this acid again mixes with the water of the water bodies, which already has acid, causing the water to become more concentrated.
The answer is C. Norway, Sweden and Finland.

Primeiramente, podemos citar o fato de que diversas potencias europeias foram responsáveis pela colonização de vários países, principalmente os localizados no continente americano. Isso, portanto, fez com que aspectos como a religião católica, as linguás e os costumes culinários, sejam aspectos que demonstram a hegemonia europeia presente no mundo atual, já que tais aspectos são oriundos desse continente.
