Geography

<span>The orbital period will be 5.196 earth years. The period of an orbit is proportional to the square root of the cube of the semi-major axis. The semi-major axis of earth is 1 AU (actually 1.000001018 AU, but for this problem 1 is close enough). The hypothetical planet will have a semi-major axis of 3 AU. So making the ratios with earth's year being 1, earth's semi-major axis being 1, the planet's year being y, and the planet's semi-major axis being 3, we get the following ratio. 1 / 1^(3/2) = y / 3^(3/2) Raise the denominators to the 3/2 powers. 1/1 = y/5.196 Multiply both sides by 5.196 5.196 = y So the orbit period will be 5.196 earth years.</span>

What do you mean by mohorovicic discontinuity ​
Lera25 [3.4K]

Answer:

The Moho is the boundary between the crust and the mantle in the earth. Also termed the Mohorovicic' discontinuity after the Croatian seismologist Andrija Mohorovicic' (1857-1936) who discovered it. The boundary is between 25 and 60 km deep beneath the continents and between 5 and 8 km deep beneath the ocean floor.

The Mohorovičić discontinuity usually referred to as the Moho discontinuity or the Moho, is the boundary between the Earth's crust and the mantle. It is defined by the distinct change in velocity of seismological waves as they pass through changing densities of rock.

Why doesn’t the wall of china protect the entire country?
DENIUS [597]

The main reason for the wall's construction had always been defense. Since China's first dynasty, the empire faced a near-constant threat of attack from the nomadic tribes to the north. This included those famed Mongols as well as lesser-known groups like the Xiongnu and the Göktürks.
