Which of the following soil types is richest in organic material?

2 answers:

I believe the correct answer from the choices listed above is option B. The soil type that is the richest in organic material would be a dark-colored soil. Decaying matter turns brownish-black which makes this type of soil having a dark color even almost black.

Correct answer choice is :

B) Dark-colored soil

Explanation:

Organic matter, organic matter, or actual organic matter leads to the large provisions of carbon-based composites located within natural and engineered, physical and marine ecosystems. Organic matter is made up of plant and animal deposits in various phases of decomposition, cells of soil microorganisms, and matters that are so well-decomposed it's difficult to tell what they were, to start with.

When you are on a roller coaster, you are constantly transforming from Potential to Kinetic energy and back. Explain how these e

andreev551 [17]

Answer:

The two types of energy possessed by the roller coaster are:

- Potential energy: it is the energy possessed by the roller coaster due to its position. It is calculated as

$PE=mgh$

where

m is the mass of the roller coaster

g is the acceleration due to gravity

h is the height of the roller coaster relative to the ground

- KInetic energy: it is the energy possessed by the roller coaster due to its motion. It is calculated as

$KE=\frac{1}{2}mv^2$

where

v is the speed of the roller coaster

Moreover, according to the law of conservation of energy, the total mechanical energy of the roller coaster (the sum of potential+kinetic energy) is constant during the motion:

$E=PE+KE=const.$

This implies that:

- When PE increases (because h increases), KE decreases (because v decreases)

- When PE decreases (because h decreases), KE increases (because v increases)

Now we can apply these conclusions to the motion of the roller coaster:

- When it moves from A to B, potential energy is converted into kinetic energy, so PE decreases and KE increases

- When it moves from B to C, kinetic energy is converted into potential energy, so PE increases and KE decreases

- When it moves from C to D, potential energy is converted into kinetic energy, so PE decreases and KE increases

- When it moves from D to E, kinetic energy is converted into potential energy, so PE increases and KE decreases

What changes in airplane longitudinal control must be made to maintain altitude while the airspeed is being decreased?

garik1379 [7]

Explanation:

The changes can be made in airplane longitudinal control to maintain altitude while the airspeed is being decreased is

We can increase the angle of attack this would compensate for the decreasing lift. As the angle of attack directly controls the distribution of pressure on the wings. Moreover, increase in angle of attack will also cause the drag to increase.

You are driving at 50 miles per hour. If you decrease the time it takes you to travel 1 mile by 8 seconds, what is your new spee

Dmitriy789 [7]

Answer:

The new speed is 56.25 miles/hour.

Explanation:

Since speed = distance/time;

time = distance/speed.

While driving at 50 miles/hour, time taken for one to complete 1 mile is (1/50) hour

(1/50) hour = (1/50) × 3600s = 72 seconds.

So, if this time to complete 1 mile (72 seconds) is reduced by 8 seconds,

New time to complete 1 mile will be = 72 - 8 = 64 seconds = (64/3600) hour = 0.0178 hour

New speed would be = (1 mile/64 seconds) = (1 mile/0.0178 hour) = 56.25 miles/hour.

Hope this Helps!!!

In the article “Who Shaped our Behaviors? Peers or Parents?”, Judy Rich Harris suggests that __________ are the most influential

Olegator [25]

<span>In the article “Who Shaped our Behaviors? Peers or Parents?”, Judy Rich Harris suggests that C. peers are the most influential in forming children's personalities.
When a child is young, it is very impressionable and will follow other people's influence easily. Usually, that influence comes from other kids who can do something, and then your child will want to do the same thing. So peers are crucial when forming a personality at such a young age.</span>
