The distance of separation of the two cars after 12.0 seconds is 102 m

Final velocity, v of A = 12.5 m/s

Final velocity, v of B = 45 m/s

<h3>What are the distance apart of the two car after 12 seconds?</h3>

The distance of separation of the two cars after 12.0 seconds is calculated as follows:

  • The distance travelled by A = velocity * time

Distance travelled by A = 12.5 * 12.0

Distance travelled by A = 150 m

Distance travelled by B is calculated as follows:

  • Distance, s = ut + 1/2at²

u = 0, t = 12.0, a = 3.5 m/s²

Distance travelled by B = 0 * 12.0 + 1/2 * 3.5 * 12²

Distance travelled by B = 252 m

The distance of separation of the two cars after 12.0 seconds = 252 - 150 The distance of separation of the two cars after 12.0 seconds = 102 m

Final velocity, v of A = 12.5 m/s

Final velocity, v of B is calculated as follow;

v = u + at

v = 0 + 3.5* 12

Final velocity of B, v = 45 m/s

In conclusion, the distance of separation and final velocities are determined from the given values of initial velocity and acceleration.

If a 50 kg student is standing on the edge of a cliff. Find the student’s gravitational potential energy if the cliff is 40 m hi
saul85 [17]
The gravitational potential energy:
E p = m x g x h
where m is the mass and h is the height;
m = 50 kg,  g = 9.81 m/s² ,  h = 40 m
E p = 50 kg  x 9.81 m/s²  x  40 m
Answer:
E p = 19,620 J = 19.62 kJ

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.
