Answer:

1.Nitrification happens when soil organisms change over ammonium into nitrate. Much of the cover between the carbon cycle and the nitrogen cycle happens within the soil, in forms conducted by soil organisms. Organisms break down supplements, construct modern compounds for their possess development, and inevitably pass on.

The second question im not sure sorry- the positive and negative one ;(

3. Many human activities have a significant impact on the nitrogen cycle. Burning fossil fuels, application of nitrogen-based fertilizers, and other activities can dramatically increase the amount of biologically available nitrogen in an ecosystem. As nitrogen makes up 78% of the atmosphere, there is no shortage of it – it just isn't in a form plants and animals can use.

4. Carbon makes its way through living things as carbon-based compounds, like vitality particles, fats and proteins, in the long run cycling its way back into the environment. Nitrogen is basically found within the air as well and enters the environments as supplements for plants. Water, nitrogen and carbon cycles. Carbon moves from the air and back by means of creatures and plants. Nitrogen moves from the environment and back by means of living beings. Water moves on, over, or underneath the surface of the Soil.

5. Carbon cycle, Nitrogen cycle, Nutrient cycle, Oxygen cycle, Phosphorus cycle, Sulfur cycle, Rock cycle, Water cycle.

6. Wind, water, and ice disintegrate and shape the arrive. Volcanic movement and seismic tremors change the scene in a sensational and frequently savage way. And on a much longer timescale, the development of earth's plates gradually reconfigures seas and landmasses. Each one of these forms plays a part within the Cold and Antarctica.

People affect the physical environment in numerous ways: overpopulation, contamination, burning fossil powers, and deforestation. Changes like these have activated climate alter, soil disintegration, destitute discuss quality, and undrinkable water. Earth's surface is the as it were territory accessible to the human race. Understanding the forms by which that environment has been made and persistently changed is critical to decide the causes of natural degradation.

In series circuit, Req = R₁ + R₂ + R₃ + ···

In parallel circuit, \frac{1}{Req}  = \frac{1}{R1} + \frac{1}{R2} + \frac{1}{R3} +...

<h3>Q7.</h3>

total resistance in the upper branch = R₂ + R₃ = R₂ + 2

\frac{1}{Req} = \frac{1}{R2+R3} + \frac{1}{R1}

\frac{1}{4} = \frac{1}{R2+2} +\frac{1}{6}

R₂ + 2 = 12

R₂ = 10Ω

<h3>Q8.</h3>

\frac{1}{Req} = \frac{1}{R2+R3} + \frac{1}{R1}

\frac{1}{Req} = \frac{1}{2+1} + \frac{1}{4}

Req = 1.7Ω

How does a wind turbine transform mechanical energy into electrical energy?
Alex777 [14]

Answer:

"A turbine takes the kinetic energy of a moving fluid, air in this case, and converts it to a rotary motion. As wind moves past the blades of a wind turbine, it moves or rotates the blades. These blades turn a generator."

Much of the oil and natural gas in the united states is located in
lana66690 [7]

Answer:

oil production in the USA are majorly from this states:

1.Texas

2. North Dakota

3. California

4. Alaska

5. New Mexico

6. Oklahoma

7.Colorado

8. Wyoming

Explanation:

While other states have seen a boom in recent years, Texas is still the epicenter of the U.S. oil industry, with 27 operable refineries, more than any state. Texas produced 1.2 billion barrels of oil in 2014, which accounted for 36% of total U.S. output, and the state has almost one-third of all proven oil reserves with 10.5 billion barrels.

A 5.00 kg crate is suspended from the end of a short vertical rope of negligible mass. An upward force F(t) is applied to the en
gayaneshka [121]

Answer: 75.05N

Explanation:

According to newton's second law,

Force = mass×acceleration

Given mass = 5.0kg

Acceleration = change in velocity/time

Velocity = change in displacement/position/time i.e dy/dt

Given position of the particle as y(t)=(2.80 m/s)t +(0.61 m/s)t³

dy/dt = 2.80 + 3(0.61)t²

V = dy/dt = 2.80 + 1.83t²

Acceleration (a) = dv/dt = 2(1.83)t

dv/dt = 3.66t

To get the force when t =4.10second

dv/dt @ t = 4.10s will be 3.66(4.10)

acceleration = 3.66×4.10 = 15.01m/s²

Magnitude of the force F = ma

F = 5.0kg × 15.01m/s²

F = 75.05N
