Answer:Nitrogen-fixing bacteria convert free nitrogen gas into nitrogen compounds. ... Bacterias that are decomposers recycle nitrogen compounds in the soil by breaking down animal wastes and dead plants and animals. 3. Other bacteria break down nitrogen compounds and release free nitrogen back into the air.
Explanation:
"The nitrogen fixing and bacteria of decay" is the two major role of bacteria in nitrogen cycle."
What is nitrogen fixing?Nitrogen fixing can be define as the process in which It is possible to see nitrogen converting to nitrate.
What is bacteria of decay?Bacteria of decay can be define as the process in which it is possible to see nitrogen waste converting to ammonia.
What is nitrogen?Nitrogen can be referred as element which is kept in boron family in the periodic table.
Therefore, the two role of bacteria in a nitrogen cycle is bacteria of decay and nitrogen fixing.

Freezing is a way to make magnets from ferromagnetic substance.
What is Curie temperature?Curie point, also known as Curie Temperature, is the temperature at which the magnetic characteristics of some magnetic materials abruptly change. Remnant magnetism manifests in rocks and minerals below the Curie point, which for magnetite, a common magnetic mineral, is approximately 570 °C (1,060 °F).
In some magnetic materials, atoms that act as small magnets spontaneously align themselves below the Curie point, which for iron is 770 °C (1,418 °F). Because the atomic magnets in each microscopic region (domain) of ferromagnetic materials, such as pure iron, are aligned in the same direction, their magnetic fields reinforce one another.

A glass rod is rubbed briefly with silk and the rod becomes able to attract and lift a number of small pieces of paper. If the rod is rubbed with silk for a longer period of time, explain what will happen and why.
QUICKLY PLEASE!
Answer:
it will have a stronger attraction force
Explanation:
If the rod is rubbed with silk for a longer period of time, then it attract large number of small pieces of paper.
When A glass rod is rubbed briefly with silk, then glass rod is heated because of rod become positively charged. That positively charged glass rod attracts the uncharged pieces of paper because some of the electrons present in the paper accumulate at the end near the rod.Learn more:

Which of the following statements is true regarding the constructive interference diagram shown below? Select all that apply.
A. The amplitude of the wave is increased.
B. During interference, the wave will produce a louder sound.
C. The amplitude of the wave is decreased.
D. The crests of two waves are overlapping.
E. The troughs of the two waves are overlapping.
There is more than one answer. Help plz
The statement i.e. true with respect to the constructive interference diagram should be that the two waves should be overlapped.
What is the constructive interference?At the time when two waves of the same kind of wavelength should be in phase so they created the new wave along with the amplitude that should be equivalent to the sum of the inidvidual amplitudes so this we called as the constructive interference
As per the given diagram, we can say that the crest for two waves that should be overlapped should be considered.

1.what is gravity?(in your own words)
2.How does gravity cause the planets to move in a circle around the sun?
Answer:
1.Gravity is an invisible force that pulls objects toward each other
2.The suns gravity pulls the planet towards the sun which changes the straight line of direction into a curve
That keeps the planet moving in an orbit around the sun
hope it helped:)
1. Gravity is an imperceptible force that pulls entities toward each other
2. When The sun's gravity pulls the planet towards.
What is Gravity?
The gravitational attraction of the original gaseous significance present in the Universe forced it to begin coalescing and creating stars and caused the stars to group concurrently into galaxies,
So, gravity is accountable for the consideration of the large-scale structures in the Macrocosm.
When the sun transforms the straight line of movement into a curve That preserves the planet pushing in an orbit almost like the sun.
The gravity pulls the sun and the planets concurrently while controlling them apart. The inertia feeds the tendency to preserve speed and keep pushing.
Nevertheless, the gravitational pull desires to reverse the motion to pull the planets into the core of the sun.

I need help with question ii) Calculate the speed of these radio waves.
I don't know if I started it right.... I need help plss!!!
Answer:
Speed = Wavelength x Wave Frequency. In this equation, wavelength is measured in meters and frequency is measured in hertz (Hz), or number of waves per second. Therefore, wave speed is given in meters per second, which is the SI unit for speed.
An model leans off a bridge railing to take a picture and accidentally drops their phone. The phone's mass is 0.115 kg and the bridge is 15 m tall. The instant the model dropped the phone, it's mechanical energy is 16.9 joules? why?
Answer:
The statement is true:
Explanation:
As said in the statement, we need to measure the mechanical energy(M.E) of the phone at the instant is dropped:
M.E = P.E + K.E
Given the fall hasn't yet begun, the kinetic energy (K.E) is equal to zero so M.E = P.E
We must use the Potential Energy formula :
P.E = h x m x g
We know that g is equal to 9.8 [tex]J.kg^{-1} .m^{-1}[/tex] on Earth, the height is 15m and m is 0.115:
M.E = 15 x 0.115 x 9.8 = 16.9 Joules
