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 .
Answer:
Eurasia
Neanderthals inhabited Eurasia from the Atlantic regions of Europe eastward to Central Asia, from as far north as present-day Belgium and as far south as the Mediterranean and southwest Asia. Similar archaic human populations lived at the same time in eastern Asia and in Africa.
Answer:
- Shape of the continents
- Fossils of the same species found on continents that are not connected
- Evidence of ice sheets in places that are hot in the present
- Mid-ocean ridges
Explanation:
The continental drift theory is a theory that suggests that the continents are always on the move, thus they change their shape, location, collide with each other, move away from each other etc.
The shape of South America and Africa is one of the evidences. If the shapes of the continents are taken out of a map, and the eastern coast of South America and western coast of Africa are merged, they fit in perfectly.
There are numerous fossils of the same species of animals and plants that have been found all over the world, even though the continents are isolated and separated by water bodies.
In some places that are very hot in the presence, like South Africa, have evidence of ice sheets. In the current conditions that is simply not possible considering that the temperature in this part of the world goes well over 40 C degrees.
The mid-ocean ridges are very nice proof of the continental drift theory. They are one of the evidence that can be observed in the present, where new crust is constantly forming and pilling up, while pushing the old crust sideways further away from it.
