The acceleration of the person in 10.4 seconds will be 0.5 m/s².
How is acceleration and force related to each other?Force is defined as the product of mass of the body and the acceleration with which it is moving. Mathematically -
F = ma
Acceleration and force are related as we can write -
a = F/m
Acceleration is a vector quantity. In the three dimensional coordinate system, the acceleration vector can be resolved as -
[a] = F[x]/m + F[y]/m + F[z]/m
Given is a person who walks from rest to 5.20 m/s in 10.4 s.
We can write -
[u] = 0 m/s
[v] = 5.20 m/s
[Δt] = 10.4 s
Substituting the values in the formula -
a = (v - u)/[Δt]
a = 5.20/10.40
a = 0.5 m/s²
Acceleration will be 0.5 m/s².
Therefore, the acceleration of the person in 10.4 seconds will be 0.5 m/s².

a scientist decided to test her hypothesis that male fiddler crabs come out morr often at dush rather than dawn. what would be the independs varible
The experiment's independent variable would be the proportion of females.
Male fiddler crabs are more busy at night than in the morning because they are looking for females to interact with.
What makes male Fiddler crabs want to attract females?Males wave their extended claw in the direction of women to entice them to have physical contact. When a female is ready for physical contact, she will emerge from her burrow and stroll among the waving men (her ovaries are ripe). Before choosing one as her partner, she visits other males (up to 24).
During a visit, the female approaches the male immediately, follows him into his burrow, stays there for a short while, and then emerges to carry on with her exploration.
The male emerges and gathers sand to block the burrow entrance five minutes after the female accepts him as her spouse. The woman then disappears into thin air.
He plugs it from the inside, burying the woman and himself in the process. She swings a bat at eggs.

Sandstone and all other types of sedimentary rock are made up of particles. The source materials of these particles consist of
O A. fragments that broke off of older rocks.
O B. magma that cooled deep below a volcano.
C. gases that condensed in the atmosphere.
O D. vegetation that decayed in thick layers.
Answer:
A. fragments that broke off of older rocks.
Explanation:
Sedimentary rocks are formed from pre-existing rocks or pieces of once-living organisms. They form from deposits that accumulate on the Earth's surface. Sedimentary rocks often have distinctive layering or bedding. Many of the picturesque views of the desert southwest show mesas and arches made of layered sedimentary rock.

NAD+ and ADP have less energy.
What are NAD+ and ADP?NAD+ is a direct precursor to numerous small molecules including ADP-ribose (ADPr), cyclic ADP-ribose (cADPr), NAADP, and O-acetyl-ADP-ribose (OAADPR); all of which are crucial second messengers that control a variety of biological processes, including cell survival, death, and inflammation.The coenzyme nicotinamide adenine dinucleotide (NAD+) is essential for redox reactions and hence plays a major role in energy metabolism. For non-redox NAD+-dependent enzymes, including sirtuins, CD38, and poly(ADP-ribose) polymerases, NAD+ is also a crucial cofactor.Adenosine pyrophosphate (APP), also known as adenosine diphosphate (ADP), is a crucial chemical component in metabolism and is necessary for the movement of energy in living cells.To learn more about NAD+, refer

when a person eat were salt with water ?
Answer:
Salt is everywhere. It’s in our pantries and on our kitchen tables. It is present in most foods we eat and some beverages we drink. It is essential for our bodies to function properly. However, it also can be dangerous, or in some cases even deadly. Recently a mother in South Carolina made headlines for killing her 17-month old daughter—using just a teaspoon of salt. For many the reaction to the story was not only shock but questions about how that was even possible. “Salt poisoning is a real thing,” says Sherrie Pace with the Utah Poison Control Center. “There are dangerous salt ingestion practices demonstrated on the Internet that some people will follow, and they don’t understand the risk”
What makes lipids/fats hydrophobic and not mix with water?
Ophosphate group at one end of the molecule
O presence of C=C (carbon double bonds)
Oglycerol
fatty acid tails
Fatty acid tails makes lipids/fats hydrophobic and not mix with water.
What is hydrophobic interaction?Hydrophobic interactions describe the relations between water and hydrophobes (low water-soluble molecules).
Hydrophobes are nonpolar molecules and usually have a long chain of carbons that do not interact with water molecules. The mixing of fat and water is a good example of this particular interaction.
Liquid water is held together by hydrogen bonds. (Liquid water has fewer hydrogen bonds than ice.) Oils and fats not have any polar part and so for them to dissolve in water they would have to break some of water's hydrogen bonds.
Thus, the fatty tails are hydrophobic in nature composed of hydrocarbon chains that are uncharged hence do not interact with water.

We have two parents with RrYy genotype.
We can see the cross with a Punnett square, and look for the seeds with genotype RRyy or Rryy, which will produce round green seeds.
As we can see, 3/16 of the seeds will be round and green, which means C) 3/16 would be the right answer.
What else is missing from this equation that a plant needs in order to do photosynthesis?
A plant needs carbon dioxide and light energy in order to perform photosynthesis.
Commonly used equation for photosynthesis is: [tex]6CO_{2}[/tex] + [tex]6H_{2}O[/tex] → [tex]C_{6}H_{12}O_{6}[/tex] + [tex]6O_{2}[/tex]. This illustrates how light energy is absorbed by chlorophyll (implied by the arrow) to turn the reactants, six carbon dioxide molecules and six water molecules, into a sugar molecule and six oxygen molecules, the products.
Photosynthesis is a process by which the plants use light energy and carbon dioxide from the atmosphere to convert into glucose sugar and oxygen. Oxygen is required by every living organism to respire and live. Whereas, glucose produced is used by plants as their food constituent and is generally stored in the form of starch.
