The factors that effect the speed of sound are not random effects based on a whim but exact scientific principles that effect the speed of sound. The exact number 1,126 feet per second is taken in some precise conditions: in dry air at 68% Fahrenheit. In other words in the most “average” conditions possible. Therefore a great average, but it is variable.
Here are the factors that effect the speed of sound:
♦ Medium
Medium has a huge effect of the speed of sound. When most people discuss the “speed of sound” they are talking about the propagation of sound waves through the medium of “Air”. For anyone who has gone underwater and listen to people talking above it is likely that one would notice the muted an “odd” way that voices sound underwater. This is because the “medium” of water greatly bends, distorts and changes the speed of sound wave.
There is a whole aspect of science that measure and defines the effect of different mediums (gaseous and liquid) on the speed of sound. This is called Fluid Dynamics. Underwater communication is possible if you understand how this wave propagation as well as another important factor (pressure).
Because of elasticity of materials sound will, as a rule of thumb, generally travel faster in solids than in liquids and faster in liquids than in gases.
♦ Temperature
Temperature has a large effect on the speed of sound. Not as much as the “Medium” does, but far more than anything else. Temperature affects the speed of sound because temperature can affect the “elastic” qualities of different mediums. At the very basics lower temperatures will decrease the speed of sound while higher temperatures will increase the speed of sound, all other factors being equal.
♦ Pressure
Pressure is the final factor that has a significant impact on the speed of sound. The effect of pressure on the speed of sound is due to the materials inertial properties. In short, the more pressure that is applied to the material or medium the denser it becomes and the greater the “inertia” becomes. This makes any interactions between particles slower. Therefore the speed of sound throughout the medium is slowed due to the greater pressure.
I hope that helps!!!

put the same number of letters in each mailbox.
How many letters did Alana put in each mailbox? 6 2×3
Answer:
Alana put mailed 2 letters in each of the 3 mailboxes
Explanation:
Alana put 2 letters in each of the 3 different mailboxes, dividing the total of 6 letters evenly.
Explanation:To answer how many letters Alana put in each mailbox, we divide the total number of letters by the number of mailboxes. Alana mailed 6 letters in total and used 3 different mailboxes. So, we perform the division 6 ÷ 3 to find the number of letters per mailbox.
6 ÷ 3 = 2 letters per mailbox.
Therefore, Alana put 2 letters in each of the three mailboxes.

How does the first meiotic division differ from the second meiotic division in terms of what is separated in anaphase I and anaphase II?
Answer:
Meiosis can be described as a process of cell division in which four daughter cells are produced and the chromosome number in the daughter cells gets reduced to half of the parent chromosomes.
In anaphase 1, the homologue chromosomes are pulled apart and they get pulled in the opposite reaction. The sister chromatids are not separated in anaphase 1.
In anaphase 2, the sister chromatids get separated. They move towards the opposite pole.

What is the answer plz ?
Answer:
18°
Explanation:
Remember this:
All angles inside a triangle sum up to 180°.
So in your case:
∠A + ∠B + ∠C = 180°
Now you need to solve for ∠A, but you need to know what x is first. So we solve for it by plugging in the expressions into one equation. Let's start with what is given:
∠A = x -22
∠B = 3x + 19
∠C = x - 17
So we plug use the given and put it into our first equation so we can solve for x:
∠A + ∠B + ∠C = 180°
(x - 22) + (3x + 19) + (x - 17) = 180°
[tex](x - 22) + (3x + 19) + (x - 17) = 180\\\\ Combine\;like\;terms\\\\5x - 20 = 180\\\\Add\;20\;to\;both\;sides\;of\;the\;equation\\\\5x - 20 + 20 = 180 + 20\\\\5x = 200\\\\Divide\;both\;sides\;by\;5\\\\\dfrac{5x}{5}=\dfrac{200}{5}\\\\x = 40[/tex]
Now that we know that x = 40, we substitute that into the equation of ∠A.
∠A = x -22
∠A = 40 -22
∠A = 18°

1. Photosynthesis and cellular respiration are often described in two ways: (1) They are chemically opposite; and (2) They have a relationship to each other. Explain what these two statements mean. Be sure to include the specific substances used and released by each process.
Answer:
Photosynthesis and cellular respiration are chemically opposite. The reactants of photosynthesis are energy, carbon dioxide (6CO2), and water (6H2O). The products of cellular respiration are energy, carbon dioxide, and water. The products of photosynthesis are glucose (C6H12O6) and oxygen (6O2), and the reactants of cellular respiration are glucose (C6H12O6) and oxygen (6O2). So, the processes' equations are chemically opposite. The relationship between photosynthesis and cellular respiration is such that the products of one system are the reactants of the other. Without photosynthesis, cellular respiration couldn't take place, and without cellular respiration, photosynthesis couldn't take place. It's like a cycle.
Explanation:
Photosynthesis and cellular respiration are often described in two ways: (1) They are chemically opposite; and (2) They have a relationship to each other. One is anabolic and one is catabolic.
What is photosynthesis ?It is the process by which plants prepare their food in the presence of sunlight with the use of water, carbon dioxide and this makes the glucose along with the release of energy.
Photosynthesis is the process in which the carbon dioxide along with water and sunlight binds up together in order to form glucose or the energy source that is the produced byproduct of photosynthesis.
Cellular respiration is the catabolic process where the carbon dioxide along with the water molecules break into energy. The product of cellular respiration is carbon dioxide and water with the formation of ATP,NADPH.

Why are igneous rocks the best type of rock sample for radiometric dating
Answer:
Because igneous Rock is separated into different minerals. Radio carbon dating works by measuring the amount of carbon dioxide.
Due to the diverse minerals that are extracted from igneous rock. The process of radio carbon dating involves counting the amount of carbon dioxide.
What is radiometric dating?The best sorts of rocks samples to utilize for radiometric dating are igneous rocks. Elements are divided up into various minerals in the rock during the formation of igneous rock.
When minute quantities of radioactive impurities are created, they can be selectively integrated into materials like rocks and carbon, which is how radiometric dating, radio dating, or radioisotope dating is used to date them.
Therefore, when minerals in igneous rocks first develop, they frequently only contain the parent isotope and none of the daughter isotope.

what would be the most likely result if humans stopped burning fossil fuels?
A) the greenhouse effect would become stronger.
B) the sea levels would rise more quickly.
C) there would be less carbon dioxide in the atmosphere.
D) the planet would become much warmer.
Explanation:
C) there would be less carbon dioxide in the atmosphere.
An environment's biology includes both abiotic factors like atmosphere, water, soil, sunlight and temperature; and biotic factors which are living components of the ecosystem. These factors lead to a gradual change of an ecosystem over time; however, humans drastically impact the environment through over-exploitation and pollution- we disrupt normal abiotic and biotic interactions. Furthermore, human impact can lead to population die-offs and extinction events, along with food and water scarcity.
Humans impact on the environment can manifest as:

What is an example of mechanical weathering by gravity
Answer:
Abrasion
Explanation:
Mechanical weathering is generally called physical weathering where rocks are broken down physically. It means that the rocks are broken down into smaller pieces but the rocks' composition (chemically) is not changed.
There are different ways that rocks can be broken into smaller pieces physically and gravity helps can also cause it.
Abrasion is an example of mechanical weathering where rocks bump into each other and cause the rocks to breakdown because of the force of bumping into each other. Gravity plays a role when it comes to rocks on the mountain side.
When a rock on top tumbles down the side of the mountain, it bumps into other rocks along the way. Gravity is at play here because it pulls the rock downwards, causing it to tumble.
Select the most correct statement regarding nucleus acids
Explanation:
Nucleic acids are the biopolymers, or small biomolecules, essential to all known forms of life. The term nucleic acid is the overall name for DNA and RNA. They are composed of nucleotides, which are the monomers made of three components: a 5-carbon sugar, a phosphate group and a nitrogenous base
Final answer:
Nucleic acids are acidic due to their phosphate groups which can release a proton ionized at physiological pH levels, making them essential for cellular functions.
Explanation:
The most correct statement regarding nucleic acids is that they are acidic compounds first discovered in the cell nucleus and later found in the cytoplasm, mitochondria, and chloroplasts. Nucleic acids are high molecular weight, nitrogenous organic compounds essential for the storage, transmission, and control of cellular activities. A nucleic acid is defined as a polynucleotide, which is a polymer chain consisting of thousands of nucleotide units. Each nucleotide is made up of a nucleoside and phosphoric acid.
An acid is a substance that releases hydrogen ions (H+) in a solution. A positively charged hydrogen ion is simply a proton, which is prone to participate in chemical reactions. Nucleic acids release a proton (H+) from their phosphate group that is ionized at physiological pH, contributing to their acidic properties. Strong acids ionize completely in solution, while weak acids do not ionize fully, with some hydrogen ions remaining bonded within a compound.
In essence, nucleic acids are considered acids because each phosphate group in the nucleotide has one acidic hydrogen atom that gets ionized at physiological pH levels, making these compounds acids in the biological context.

Which is the function of the enzyme DNA polymerase during replication?
A) bonds mRNA to original parent strand
B) bonds new nucleotides to parent strand
C) unwinds the replicated DNA strand
D) winds up the replicated DNA strand
Answer:
The correct option is B) bonds new nucleotides to parent strand
Explanation:
DNA replication is a process by which DNA replicates by a semi-conservative method. The DNA double helix unwinds from the place where replication has to occur. Each strand of the DNA serves as a template strand for producing a daughter strand.
The DNA polymerase adds nucleotides complementary to each parent strand. In this way, a daughter strand is generated from the parent strands. This method of replication is termed as the semi-conservative method for DNA replication.
DNA polymerase is a crucial enzyme in DNA replication, its main role being to bond new nucleotides to the parent strand, thereby creating a new, complementary strand of DNA.
Explanation:The function of the enzyme DNA polymerase during replication is to bond new nucleotides to the parent strand. The parent strand is the original DNA sequence, and DNA polymerase attaches the new nucleotides in a specific order to create a new strand of DNA, which is a complementary strand to the parent strand. This process ensures that the genetic information is accurately copied from one cell to another during cell division.

What is Malthusian theory ?
In his essay "An Essay on the Principle of Population" from 1798, English economist and demographer Thomas Malthus predicted that population increase would eventually outpace the supply of resources, particularly food. He stated that although the production of resources and food only develops arithmetically (linearly), the growth of the human population is geometric (exponentially).
Therefore, He anticipated that unregulated population increase would result in resource shortages and overpopulation, which would cause poverty, starvation, and other societal problems. The "Malthusian theory" is the name given to Malthus' population theory, which has been the subject of dispute and discussion ever since.
