Oldest to youngest- D, A, E, B, C
It's called relative dating, you basically find the rocks that are at the very bottom (oldest), look for the ones that are on the top (younger), but if you find any that are cross cutting, those are the youngest of them all.

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 .

In our Solar System the mass is primarily at the center, so the orbital speed of the planets decreases with distance. In a galax

Answer:

Check Explanation.

Explanation:

In order to be able to answer this question effectively and efficiently we have to consider the Newton's law of Universal gravitation which is given by the mathematical representation below;

Gravitational force, F = G (m1 × m2) / r^2.

Where G = Gravitational constant, m1 and m2 and the masses of body one and two respectively and r = distance.

So, we can deduce that the mass(in form of kinetic energy) increase at large distance and this makes the speed to reduce.

There has been a recent increase in the frequency and magnitude of tropical cyclones. How could we link this to global warming?

Dmitrij [34]

Hello, Nadsdsss!! Global warming has occurred due to increase in greenhouse gases, along with many other things. The greenhouse gases include carbon dioxide (CO2), methane (CH4), and nitrous oxide (N20). Take CO2 for example, when we emit more CO2 into the atmosphere, it will cause a blanket trapping in the heat from the sun, which will cause heat to increase. With heating the atmosphere comes heating the ocean more and allow glaciers and ice to melt, which will cause sea rise. With both of these happening because of global warming, this causes more hurricanes within the world. Throughout the past few years, there has been a substantial amount of hurricanes that have increased due to global warming. I hope I helped!! If you have any more questions then feel free to message me and I will answer them for you. Have a great day.
