Describe the components of soil

rusak2 [61]

Soil contains air, water, and minerals as well as plant and animal matter, both living and dead. These soil components fall into two categories. ... Other, less common minerals include calcium, magnesium, and sulfur. The biotic and abiotic factors in the soil are what make up the soil's composition.

Facts about soil: Soil is a mixture of organic matter, minerals, gases, liquids, and organisms that together support life.

What does soil do to our earth: Advances in watershed, natural resource, and environmental sciences have shown that soil is the foundation of basic ecosystem function. Soil filters our water, provides essential nutrients to our forests and crops, and helps regulate the Earth's temperature as well as many of the important greenhouse gases.

An object starts from rest at the origin and moves along the x axis with a constant

Alika [10]

Answer:

6.9m/s

Explanation:

Given parameters:

Acceleration of the object = 4m/s²

Distance = from x; 2m to x; 8m

Unknown:

Average velocity = ?

Solution:

From the given parameters, we use the right motion equation to solve the problem.

v² = u² + 2aS

v is the final velocity

u is the initial velocity

a is the acceleration

S is the distance covered

Distance = 8m - 2m = 6m

Initial velocity = 0m/s

The final velocity gives us the average velocity in this problem;

v² = 0² + (2 x 4 x 6) = 48

v = √48 = 6.9m/s

The formula h = -16t squared + 64t squared gives the height, h, and time, t, of an object launched from the ground with a speed

padilas [110]

Answer:

Details in the explanation

Explanation:

Vertical Launch

When an object is thrown vertically in free air (no friction), it moves upwards at its maximum speed while the acceleration of gravity starts to brake it. At a given time and height, the object stops in mid-air and starts to fall back to the launching point until reaching it with the same speed it was launched.

We are given an expression for the height of an object in function of time t

$h = -16t^2 + 64t$
