How does nitrogen from the air get into the bodies of plants and animals?
Nitrogen is fixed from the atmosphere into a usable form for plants by nitrogen-fixing bacteria, which convert N₂ into nitrates. Plants absorb these nitrates, which are then passed on to animals when they consume the plants. Soil bacteria play a key role in recycling nitrogen back into the atmosphere.
Explanation:Nitrogen Fixation and the Nitrogen CycleNitrogen from the air gets into the bodies of plants and animals primarily through a process called nitrogen fixation. This is carried out by special bacteria known as nitrogen-fixing bacteria. These bacteria convert nitrogen gas (N₂), which plants cannot use, into a form that plants can absorb and utilize. The most common form is nitrate (NO₃⁻), which plants take in through their roots. Animals then obtain nitrogen by consuming plants or other animals that have eaten plants. After the nitrogen has been utilized by living organisms, bacteria in the soil convert waste products and dead organisms back into nitrogen gas through a process called denitrification, completing the nitrogen cycle.
There are different types of nitrogen-fixing bacteria, some live freely in the soil, while others form symbiotic relationships with the roots of certain plants, such as legumes. Cyanobacteria and Rhizobium are notable members of the nitrogen-fixing bacteria group. Additionally, lightning can also transform atmospheric nitrogen into nitrate, providing another source for the nitrogen cycle.

When using a calorimeter, the initial temperature of a metal is 70.4C. The initial temperature of the water is 23.6C. At the end of the experiment, the final equilibrium temperature of the water is 29.8C. What is the final temperature of the metal? ____ C What is the temperature change of the water? ____ C What is the temperature change of the metal? ____ C
temperature of a metal is29.8
temp. of water is 6.2
temp. change of metal -40.6
Answer:
The final temperature of metal is [tex]29.8\degree \,\mathrm C[/tex].
The temperature change of water is [tex]6.2 \degree \, \mathrm C[/tex]
The temperature change of the metal [tex]-40.6 \degree \, \mathrm C[/tex]
Explanation:
The term equilibrium means initial temperature and final temperature will be same. Thus, the the temperature of the water at thermal equilibrium, the final temperature of the metal must be the same [tex]29.8\degree \,\mathrm C[/tex].
Find the temperature change of water.
[tex]\mathrm {Change \, of\, temperature} =\mathrm{ Final\, temperature} - \mathrm {Initial\, Temperature}\\=29.8\,\mathrm C-23.6\,\mathrm C\\=6.2\,\mathrm C[/tex]
Find the temperature change of metal.
[tex]\mathrm {Change \, of\, temperature} =\mathrm{ Final\, temperature} - \mathrm {Initial\, Temperature}\\=29.8\,\mathrm C-70.4\,\mathrm C\\=-40.6\,\mathrm C[/tex]

Waves transfer energy. What have you observed about light, sound, or water that could support this claim?
Light, sound, or water support the claim that waves transfer energy. The speed of light and sound is the same in some cases.
What is a wave?A wave is a phenomenon that flows across a material medium without leaving any lasting mark. Mechanical or electromagnetic waves can be used to classify them. Transverse and longitudinal are the two main forms.
Waves transfer energy by causing particles to vibrate, yet the particles themselves travel in a perpendicular direction to the wave's horizontal movement.
As the particles travel from rest to movement and back to rest, energy is changed between potential and kinetic energy.
Hence light, sound, or water support the claim that waves transfer energy.

What is the Coriolis effect?The Coriolis Effect can be described as an apparent effect formed by a rotating frame of reference. The effect takes place when an object moves along a straight path. The Earth which rotates at a fixed speed is the moving frame of reference.
Coriolis force is defined as the perpendicular to the object’s axis. The Coriolis force acts north-south as the Earth spins on its axis from west to east and the Coriolis force is zero at the Equator.
Coriolis force appears to deflect the objects and kind of invisible force. The Coriolis force is calculated by the rate of rotation and mass of the object.
The Coriolis effect generates wind patterns that travel to the east toward the equator and to the west toward the poles near the earth’s surface. These prevailing wind patterns are accountable for moving clouds around the globe and creating weather in different regions.

a small 24 kilogram canoe is floating downriver at a speed of 3 m/s.what is the canoe's kinetic energy .
{~please help fast ~}
That all depends who's measuring it.
... If one Physics student is standing on the riverbank, watching the canoe float by, he will measure the canoe's kinetic energy and say it's 108 Joules.
... If another Physics student is sitting on another boat, floating on the same river and watching the same canoe, she will say that the canoe has zero kinetic energy.
Both of them are correct.
Explanation :
Mass of the canoe, m = 24 kg
Speed of the canoe, v = 3 m/s
Kinetic energy is said to be possessed due to the motion of the object and it is given as :
[tex]E_k=\dfrac{1}{2}mv^2[/tex]
v is the velocity of the canoe.
[tex]E_k=\dfrac{1}{2}\times 24\ kg\times (3\ m/s)^2[/tex]
[tex]E_k=108\ J[/tex]
So, the kinetic energy of the canoe is 108 J
Hence, this is the required solution.

How do tests with crash dummies, seat belts, and air bags illustrate newton’s First law of motion
Answer:
Newton law of inertia.
Explanation:
Newton first law states that if any object is in the motion or is in the state of rest then it will remain in that state till the external force is applied on that object. Inertia is the main reason of having seat belts and air bags in the car.
In this case, when seat belt trapped into the passenger than passenger experience same state of motion as car has.
When the car experience any kind of the collision then the car will stop abruptly. In this case seat belt and air bag will help in stopping the motion of passenger in the forward direction.
Therefore Newton's law of inertia is illustrated in test with seat belts, crash dummies, and air bags.
