What would cause soil horizons to become mixed?

AfilCa [17]

Answer:

The process of soil formation generally involves the downward movement of clay, water, and dissolved ions, and a common result of that is the development of chemically and texturally different layers known as soil horizons. The typically developed soil horizons, as illustrated in Figure 5.16, are: O — the layer of organic matter A — the layer of partially decayed organic matter mixed with mineral material E— the eluviated (leached) layer from which some of the clay and iron

Before colliding the momentum of block A is +15.0 kg*m/s, and block B is -35.0 kg*m/s. after, block A has a momentum -12.0 kg*m/

UkoKoshka [18]

The momentum of block B afterwards is $-8.0 kg m/s$ .

Explanation:

We can solve this problem by applying the principle of conservation of momentum.

In fact, the total momentum before and after the collision must be conserved. Therefore, we can write:

$p_A + p_B = p_A' + p_B'$

where:

$p_A = +15.0 kg m/s$ is the initial momentum of block A

$p_B = -35.0 kg m/s$ is the initial momentum of block B

$p_A' = -12.0 kg m/s$ is the final momentum of block A

$p_B'$ is the final momentum of block B

Solving for $p_B'$ , we find:

$p_B' = p_A + p_B - p_A' = +15.0 +(-35.0) - (-12.0)=-8.0 kg m/s$

So, the momentum of block B afterwards is $-8.0 kg m/s$ .

Answer:

Electrons

Explanation:

Conductors can be charged by electrons, while insulators cannot. Insulators inhibit the flow of electrons; conductors allow free flow of electrons.
