Describe the difference between a soil horizon and a soil profile

Physics

Answer:

The particles that accumulate on the rocks as time passes transform into the so-called integral soil profile. This profile is characterized by having different soil horizons, which are the different processes of soil formation, for example:

-the upper horizon is an area where organic matter accumulates, which provides enough carbon dioxide and some organic compounds.

-the next horizon is what is known as the leaching zone, where the different mineral materials dissolve due to the water that seeps into the soil.

-the next horizon is the so-called accumulation zone, where the chemicals that are dissolved in the filtered water are deposited and transformed into minerals

-the last horizon is the so-called transition zone, where the new material originates.

Soil profile includes all the sections/ horizons of the vertical soil depth from top to bottom including the transitions from one horizon to another. A soil horizon is a distinct layer/section of soil with more or less the same texture. Therefore, a soil profile is made of soil horizons.

Doc Brown has calculated his Delorean can accelerate at a rate of 2.52 m/s/s. How
GREYUIT [131]

Answer:

304.89m

Explanation:

Given

acceleration a = 2.52m/s²

final speed v = 39.2m/s

initial speed = 0m/s (car accelerates from rest)

Using the equation of motion below to get the distance of Doc brown from Marty;

v² = u²+2as

substitute the given parameters

39.2² = 0²+2(2.52)s

1536.64 = 0+5.04s

divide both sides by 5.04

1536.64/5.04 = 5.04s/5.04

rearrange the equation

5.04s/5.04 = 1536.64/5.04

s = 304.89m

Hence He and Marty must stand at 304.89m to allow the car to accelerate from rest to a speed  of 39.2 m/s?

A train slows down from 34 m/s to 4 m/s in 60 seconds. what is it's acceleration?
OverLord2011 [107]
Acceleration = change in velocity / time

change in velocity = final velocity - initial velocity

because the object is slowing down, the acceleration will be negative.

acceleration = (4-34) / 60
acceleration = -30 / 60
acceleration = -0.5 m/s^2

answer : the train is accelerating at -0.5 m/s^2
