I just want this information cuz it will come in handy in science soon. Where and how are Gamma rays found?

Gamma rays are found in extremely hot regions and they have the smallest wavelength but the most energy. They can be found by the effects they have on matter and it do few basic things with matter, it can collide with a electron and bounce of it as a billiard ball.

The decomposition of ammonia to the elements is a first-order reaction with a half-life of 200 s at a certain temperature. How l

Feliz [49]

Based on the half-life of the reaction, time taken for the partial pressure of ammonia to decrease from 0.100 atm to 0.00625 atm is 800 seconds.

<h3>What is the half-life of a substance?</h3>

The half-life of a substance is the time taken for half the amount of atoms present in that substance to decay.

The half-life of the reaction is 200 seconds.

After, one half-life, pressure reduces to 0.0500 atm

After, two half-lives, pressure reduces to 0.0250 atm

After, three half-lives, pressure reduces to 0.01250 atm

After, four half-lives, pressure reduces to 0.00625 atm

Time taken = 4 * 200 = 800 seconds

Therefore, time taken for the partial pressure of ammonia to decrease from 0.100 atm to 0.00625 atm is 800 seconds.

Rama09 [41]

I believe the answer would be polygenic. The word translates to "multiple genes". This occurs when many genes make up one specific thing such as our hair color or eye color.

In the Zeeman effect, the energy levels of hydrogen are split by a magnetic field. Each state with a different value of mlml has

Nikolay [14]

Answer:

the Zeeman effect without spin is three lines

Explanation:

The Zeeman effect is the result of the interaction of the magnetic field with the orbital angular momentum of the electrons, if we do not take the spin into account it is called the Normal Zeeman effect.

Therefore we only take into account the orbital moments (m_l) of the transition, from the selection rules of the refreshed harmonics, only the transition with

$\Delta m_l$ = 0, ± 1

ΔE $\DeltaE = \mu_B \ \Delta m_l \ B$

Let's analyze for the case of the Hydrogen atom

For a transition between levels n = 1 and n = 2 the values of m_l are n_f = 1 m_l = 0 and for n₀ = 2 m_l = 0, 1

so we only have two lines.

For transition n_f = 2 and n₀ = 3

n_f = 2 m_l = 0, 1

n₀ = 3 m_l = -1, 0, 1

There are only two lines plus the central line, so there are three spectral lines

for n_f = 3 and n_o = 4

n_f = 3 ml = -1, 0, 1

n₀= 4 ml = -2, -1, 0, 1, 2

Only transitions with Δm_l = ±1 are allowed, so there are only two transitions plus the central transition (Δm_l = 0), so there are only 3 spectral lines.

In summary, due to the selection rule of spherical harmonics, the greatest number of lines in the Zeeman effect without spin is three lines.

"Water is absorbed in the intestine through which process"? a. simple diffusion b. active transport c. active diffusion d. facil

sdas [7]

Answer: Water is absorbed in the intestine through gradient transport. The correct option is E.

Explanation:

Absorption of water in the mammalian intestines occurs largely on the small intestine through a transport mechanism known as osmosis. Osmosis is the movement of water molecules, through a semi permeable membrane, from the region of lower solute concentration into higher solute concentration to attain an equilibrium.

For water molecules to be absorbed from the lumen into the bloodstream, it's dependent on sodium absorption. This follows the following steps:

-sodium is absorbed by co transport with glucose and amino acids.this aids to move sodium from lumen into the enterocyte.

- Rapid exportation of absorbed sodium through sodium pimps from the enterocyte.

- As sodium is pumped out of cells an osmotic gradient is formed across apical cell membrane, this helps to osmotically drive water across the epithelium. Therefore water is absorbed in the intestine through the osmotic gradient created by sodium absorption. I hope this helps. Thanks.

The cheetah, the fastest of land animals, can run a distance of 274 m in 8.65 s at its top speed. What is the cheetahs tips spee

ycow [4]

Answer:

Top speed is 31.68 m/s

Explanation:

Speed of a body is the distance traveled by the body in unit time.

Speed is generally expressed in meter per second or kilometer per hour.

Here, the cheetah travels a distance of 274 m in 8.65 s.

Therefore, speed of cheetah is the distance traveled by it in one second.

For 8.65 s, distance traveled is 274 m

For 1 s, distance traveled will be $\frac{274}{8.65}$ meters per second. This value is called speed.

So, speed is given as the ratio of the distance traveled to that of the time taken.

∴ Top speed of cheetah is given as:

$v_{max}=\frac{274}{8.65}=31.68 \textrm{ m/s}$

Here, $v_{max}$ is the top speed of cheetah.
