Help me out a bit! This may be a bit hard but still guys, you can do this question!!!!!!!!!
ra1l [238]

Layers of the soil are called horizons. Here are the horizons:

  • Humus
  • Topsoil
  • Subsoil
  • Fragmented rock
  • Bedrock

Once a soil has developed, it forms layers called horizons. Beneath a surface layer of a plant remains, the topsoil is rich in decomposed plants and animal matter. The subsoil is mainly mineral particles, with much less organic material. The fragmented rock/bedrock is primarily small stones, and beneath it lies all bedrock.

Hope this answer helps you!

3) When the temperature of a blackbody increases from 900 K to 2300 K, by what factor does the total power of the electromagneti
LekaFEV [45]

Answer:

The electromagnetic radiation per-unit- area increase by 42.65 times.

Explanation:

The radiation per-unit- area (P) is directly proportional to the fourth power of the temperature. Thus,

P ∝ T⁴

For, when the temperature is raised from T₀ to T₁ , the radiation per-unit- area is related to as:

\frac {P_1}{P_0}=\frac {T_1^4}{T_0^4}

T₀ =  900 K

T₁ = 2300 K

\frac {P_1}{P_0}=\frac {2300^4}{900^4}

So,

<u>P₁ = 42.65 P₀</u>

<u>The electromagnetic radiation per-unit- area increase by 42.65 times.</u>

What motivated and sustained the long distance commerce
Setler [38]

Answer:

Silk Roads, Sea Roads, and Sand Roads?

Explanation:

The desire of elites for hard-to-find luxury items

from distant parts of the Eurasian network, as well as

the accumulation of wealth, especially among

merchants who participated in the trade, motivated

long-distance commerce. Sustaining the commerce were the support of empires and smaller states that benefited directly from the trade; the spread of religious traditions, including Islam and Buddhism, that through shared beliefs tied merchants and sometimes whole societies together over wide regions; and the development of technologies like larger ships and the magnetic compass.
