The **statement **that illustrates how progress in **engineering **has affected the **natural environment** is extracting mineral **resources **with modern mining equipment removes fertile **topsoil**.

<h3>What is the Natural Environment?</h3>

The **natural environment** may be defined as **anything **that can be present in the **surroundings **of living entities whether it is a **biotic **or **abiotic** factor.

The utilization of contemporary **mining **tools terminates **fertile **topsoil and admiringly impacts the **fertility **of the soil. It is tough to rebuild **topsoil **and modern mining tools constantly damage** soil fertility**.

**Advancement** in engineering has influenced the **natural environment** and **mining **is one of the most accepted **measures **of this.

The **complete **question is as follows:

**Extracting **mineral resources with **modern **mining equipment removes **fertile **topsoil.- Mining companies use modern equipment to extract mineral resources more efficiently.
- Modern mining equipment has improved the health and safety of workers.
- Modern mining practices provide materials that can be used for technological advances.

Therefore, it is well described above.

**The average force on the ball is 287.3 N.**

**Explanation:**

The impulse exerted on an object, which is equal to the product between the force exerted and the duration of the collision, is equal to the change in momentum of the object.

If we apply this to the ball, we can write:

where

F is the force exerted on the ball

is the duration of the collision

m = 513 g = 0.513 kg is the mass of the ball

u = 12.1 m/s is the initial velocity of the ball

v = -13.1 m/s is the final velocity (negative since the ball rebounds in the opposite direction)

And solving for F, we find:

So, the magnitude of the average force is 287.3 N.

The magnification is the ratio between the size of the image

and the size of the original object

:

The sign of the magnification contains another piece of information: if it's positive, then the image is upright, if it's negative, the image is inverted. In our problem, the image is inverted, so the magnification will have a negative sign, and it will be

**Answer:A air**

**Explanation:**Of the three mediums (gas, liquid, and solid) sound waves travel the slowest through gases, faster through liquids, and fastest through solids. Temperature also affects the speed of sound.

**Answer:**

hello your question is incomplete attached below is the complete question

**answer**: Fg / Fe does not change ; it is the same nonzero value for all separations ( A )

**Explanation:**

Given that distance between proton and electron is 1 cm

Fg = Gm1m2 / r^2

where :

G ( gravitational constant )= 6.67 * 10^-11 Nm^2 / kg^2

m1 ( mass of proton ) = 1.67 * 10^-27 kg

m2 ( mass of electron ) = 9.11 * 10^-31 kg

Electrical force

Fe = kq1q2 / r^2

k = 9*10^9

hence ;

Fg / Fe = (Gm1m2 / r^2) / (kq1q2 / r^2 )

= Gm1m2 / kq1q2
