Answer:

The damaged prairie area can be restored through <em>site preparation, replanting and putting species back on the landscape.</em>

Explanation:

Prairie- this is a type of habitat with mostly grasses. It also consists of trees, occasional shrubs and flowering plants. This can be found around the world and is <em>ecologically important for providing habitats for native animals and insects.</em> It is perfectly adapted to the climate and<u><em> requires minimal maintenance.</em></u>

Once a prairie is damaged, it becomes an essential move to restore it immediately. This can be done through different human activities such as the following:

1. Site preparation- before doing anything else, it would be best to prepare the prairie site by removing debris from the fire. This will make everything easier once you start planting the crops or plants.

2. Replanting- this is probably the most essential move you can do. It would be best to plant high quality food plants that would provide nectar, pollen and seeds throughout the season. This will entice many birds and butterflies into the area. It will also make the native plants abundant which will, in turn, increase ecological diversity.

3. Putting species back on the landscape- when a wildfire occurs, it is a common sense that species also run away from their home (habitat). In order to create that natural habitat again, it would be best to put the species back to where they belong so they can restart their lives. This will resume the natural food webs and nutrient cycles.

Alecsey [184]

Answer:

0.05 cm

Explanation:

The compression of the original spring = 12 - 8.55 cm = 3.45 cm = 0.0345 m

By Hooke's law, F = ke

Where F is the applied force, k is the spring constant and e is the extension or compression. In the question, F is the weight of the car.

k = F/e = 1355 × 9.8 / 0.0345 = 384898.55 N/m

This is the spring constant of the original spring. The question mentions that the force constant of the new spring is 5855.00 N/m smaller. Hence, the force constant of the new spring is 384898.55 - 5855 = 379043.55 N/m

With the new spring installed, the compression will be

e = F/k = 1355 × 9.8 / 379043.55 = 0.035 m = 3.5 cm

The difference in the compressions of both springs = 3.5 cm - 3.45 cm = 0.05 cm

What is the maximum frictional force in the knee joint of a person who supports 76. 0 kg of her mass on that knee?
Bad White [126]

The maximum frictional force in the knee joint of a person who supports 76. 0 kg of her mass on that knee 119.28N.

Given,

m=76kg, μ=0.16, g=9.81 m/s^{2}

frictional force = mμg= 76*0.16*9.81= 119.28 N

<h3>Frictional force</h3>

An opposing force to the relative motion of two bodies in contact is known as frictional force. Always acting in the opposite direction from the direction of motion, frictional force is applied to a moving body. Because it resists motion, it aids in lowering the moving object's speed. The force is one of touch. Four broad categories can be made for the force of friction depending on the sort of motion that occurs between the two objects. Static friction is the force of friction between an object and the surface it is put on.
