Nitrogen fixing bacteria changes dead plants and animals into ammonia compounds.
<h2>What is nitrogen fixation?</h2>
Atmospheric nitrogen is converted into nitrogen oxides by the action of lightning, which helps its incorporation into the soil.
<h3>Characteristics of Nitrogen fixing bacteria</h3>
- Nitrogen is fixed by these bacteria and other prokaryotes through various metabolic processes, which convert it into different usable compounds, such as ammonia (NH3) and ammonium ion (NH4+).
- These microorganisms can be found in soil and water, or as plant symbionts.
Therefore, we can conclude that nitrogen fixing bacteria fix nitrogen from the air, that is, they originate soluble compounds by plants, such as ammonia.

Answer:
4.53482 m/s
4.506 m/s
Explanation:
= Mass of player = 75 kg
= Initial velocity of player = 4.6 m/s
= Mass of ball = 0.47 kg
= Initial velocity of ball = 15 m/s
The linear momentum of the system is conserved
The player's speed is 4.53482 m/s
In the second case the equation of momentum is
The player's speed is 4.506 m/s
Answer:
the instrument that gives this precision is the micrometer screw
Explanation:
The high precision measurements of small parts are the general vernier and the micrometer screw.
In these two instruments the same principle is used: there is a fixed rule and a mobile one that increases precision.
Let's analyze the absolute error or precision of each instrument
* For the vernier, the precision of the fixed rule is 1 mm and there are 20 divisions (the most common); therefore the precision of the instrument is
Δx = 1 mm / 20
Δx = 0.05 mm
* For the micrometer screw, the precision of the fida rule is 0.5 mm and the number of divisions is 50, therefore the precision of the screw is
Δx = 0.5mm / 50
Δx = 0.01 mm
consequently the instrument that gives this precision is the micrometer screw
Answer:
his acceleration is 3.25
Explanation:
because you do 26÷16 which =1.625×2=3.25
Net work done on student B by the Ferris wheel in moving from the top to the bottom is mathematically given as
net work done on A =0.
<h3>
Net work done </h3>
Generally the equation for the work energy theorem is mathematically given as
net work done on A = change in kinetic energy of A.
Where, angular velocity is constant.
change in kinetic energy = 0.
Hence, from work energy theorem,
net work done on A =0.
