How would you describe the relationship between the mass of a car and its kinetic energy?
a) as the mass of a car increases, its kinetic energy increases.
b) as the mass of a car increases, its kinetic energy decreases.
c) as the mass of a car decreases, its kinetic energy increases.
d) there is no clear relationship between mass and kinetic energy.

The answer is A) As the mass of a car increases, its kinetic energy increases.

Explanation:

Kinetic energy is the energy associated with bodies that are in motion, depends on the mass and speed of the body, that is, The kinetic energy of a body depends on its mass and its speed according to the relationship.

The kitenic energy is expressed by the formula:

Where the kinetic energy, (Ec) is measured in joules (J), the mass, (m) is measured in kilograms (kg) and the velocity, (v) in meters / second (m / s).

I am too lazy to do this, but I am assuming you were supposed to do this in class. I will give you ideas.

Why is soil important?  Soil is our life support system. Soils provide anchorage for roots, hold water and nutrients. Soils are home to myriad micro-organisms that fix nitrogen and decompose organic matter, and armies of microscopic animals as well as earthworms and termites.

What is soil erosion?  Soil erosion is a naturally occurring process that affects all landforms. In agriculture, soil erosion refers to the wearing away of a field's topsoil by the natural physical forces of water (Figure 1) and wind (Figure 2) or through forces associated with farming activities such as tillage.

what human activities are responsible for soil erosion happening at advance rates?     Ploughing, unsuitable agricultural practices, combined with deforestation and overgrazing, are the main causes of human-induced soil erosion

What are some effects on soil loss?  The effects of soil erosion go beyond the loss of fertile land. It has led to increased pollution and sedimentation in streams and rivers, clogging these waterways and causing declines in fish and other species. And degraded lands are also often less able to hold onto water, which can worsen flooding.

What can be done to prevent soil erosion?   Maintaining a healthy, perennial plant cover.

Mulching.

Planting a cover crop – such as winter rye in vegetable gardens. ...

Placing crushed stone, wood chips, and other similar materials in heavily used areas where vegetation is hard to establish and maintain.
