its july 4th and you are enjoying a fireworks display with your friends. explain how the sounds of firewors travel through the air to your auditory cortex. include ALL auditory structors invloved, and how they function as you take in the fireworks display
Answer:
It all comes down to the chemical reaction that happens after the fuse is lit. The burning gunpowder releases hot gas that expands rapidly; when the gas expands to the point that it runs out of room within the firework, the resulting explosion causes a blast wave.
The vibrations from that blast wave have the potential to cause permanent damage to the delicate hair cells of the inner ear.
At close range, fireworks are typically between 150 and 175 decibels—well above what's safe for your hearing.
5 ways to protect your hearing
1. Keep a safe distance
One way is to maintain a safe distance from the display. The farther you are from the sound, the less harmful the sound is to your ears, so your distance from the sound of the fireworks can make all of the difference in terms of decibel level and hearing safety. A distance of around 500 feet will still give you a great view, but without the sound pressure that can damage the tiny hair cells in the inner ear.
2. Skip the home displays
Where you view your fireworks can also affect your hearing. Experts recommend attending a community display rather than setting off your own fireworks at home. Not only are fireworks dangerous and best left to trained professionals, but there is usually a roped off area located a safe viewing (and listening) distance away from the show.
3. Bring—and wear!—earplugs and earmuffs
If you intend to sit as close to the action as possible, or if you are determined to create your own display, protect your hearing and that of your children. Inexpensive foam earplugs can be found in drugstores and pharmacies, and work well for adults; earmuffs (basically foam-filled cups that cover the ears) are better for small children because earplugs sometimes don’t fit and can be a choking hazard.
4. If you buy your own fireworks, buy these
If you are planning your own fireworks display, the good news is you can customize your selection for reduced noise. All fireworks come with a noise level rating, so selecting quieter fireworks will not only preserve a good relationship with your neighbors, it will protect your hearing as well. Quieter options include fountains, wheels, falling leaves and comets. While not completely silent, they crackle and whistle instead of creating a loud, explosive boom. All are created for spectacular visual display but less noise. If you buy fireworks, your fireworks provider should be able to direct you to those that are lower on the noise rating scale.
5. And avoid these
What to avoid? Rockets, mines and any fireworks that have many blasts strung together tightly. These fireworks are created to make as much noise as possible.
Hope this helps, have a nice day/night! :D

Answer:
-11,000
Step-by-step explanation:
Given the recursive function of a sequence to be a(n)=a(n−1)⋅10 and a(1) = -11
To find the fourth term of the sequence i.e when n = 4,
First when n = 2
a(2) = a(2-1)•10
a(2) = a(1)•10
a(2) = -11×10
a(2) = -110
When n =3
a(3) = a(2)•10
a(3) = -110×10
a(3) = -1100
When n = 4
a(4) = a(3)•10
a(4) = -1100×10
a(4) = -11,000
The 5th term of the sequence is -11,000

21. Which of the following political actions was a response against the passage of the Black
codes?
Based on historical perspective, the political actions that were a response against the passage of the Black
codes are "Congressional Republicans took control of Reconstruction."
What are Black Codes?Black Codes were codes made by the Southern states in the United States designed to restrict the freedom of African Americans such that they would still be available for the cheap labor force.
However, following the passage of Black codes, otherwise known as Jim Crow laws, around 1865 and 1866, the Congressional Republicans who were against the codes took control of Reconstruction.
One of the things that occurred after was the passage of the 14th Amendment, which decreased the Congressional representatives of any southern state that denied African Americans the vote.
Hence, in this case, it is concluded that the correct answer is "Congressional Republicans took control of Reconstruction."

A student made the table below to record his observations when mixing baking soda and vinegar in a beaker
The best evidence for the formation of a new substance is the observation of the —
A.
solid settling.
B.
solid disappearing.
C.
liquid remaining clear.
D.
bubbles forming.
Answer:
D
Explanation:
A chemical reaction is a process in which substances undergo a chemical change to form a different
substance. Mixing baking soda and vinegar will create a chemical reaction because one is an acid
and the other a base. Baking soda is a basic compound called sodium bicarbonate while vinegar is a
diluted solution that contains acetic acid (95% water, 5% acetic acid).
There are five signs that indicate a chemical reaction has occurred: odor, energy change, gas
bubbles, precipitate formation, and color change. When any of these changes occur, the reaction is
irreversible and cannot be undone. The reaction occurs once the vinegar is added to the baking
soda. In this reaction, evidence of a chemical reaction is the formation of carbon dioxide gas and gas
bubbles.
There are two separate types of reactions taking place when mixing baking soda and vinegar. The
first is called an acid-base reaction. When the two substances are mixed together, hydrogen ions in
the vinegar react with the sodium and bicarbonate ions in the baking soda. This initial reaction
results in two new chemicals: carbonic acid and sodium acetate.

Lake Superior contains 3.0 x 10^15 gallons of water. How many cubic meters of water are contained in the lake? Express your final answer in scientific notation.
Given that:
Lake Superior contains 3.0 x 10^15 gallons of water
Firstly, let's know that of 1 gallon;
1 gallon = 0.00375 cubic meter
Then, 3.0 x 10 ^15 = 3.0x10^15 x 3.785 x 10 ^-3
= 3 x 3.785 x 10^15-3
= 11.355 x 10 ^12m^3
Therefore, 11.355x10^12 cubic meters of water are contained in the lake.

Kramer and Jerry moved from New York to Los Angeles in pursuit of becoming actors. They considered all of the apartments in the area of the city they wished to live in and decided to rent one that was to their satisfaction.
Explain how each of the following is related to Kramer and Jerry’s decision to rent an apartment.
- Frontal Lobe
- Foot-in-the-door Phenomenon
Explain how each of the following concepts could be related to Kramer and Jerry’s moving their belongings into the apartment
- Social Loafing
- Cerebellum
- Broca’s Area
Provide an example that explains how each of the following concepts could be related to life for Kramer and Jerry in their new apartment in Los Angeles.
- Normative Social Influence
- Self-Fulfilling Prophecy
The frontal lobe is related to Kramer and Jerry's decision to rent an apartment in order to be the part of the brain responsible for cognitive functions such as memory, problem solving, emotions, etc.
The foot-in-the-door phenomenon relates to Kramer and Jerry's decision to rent an apartment in that this phenomenon is a compliance tactic, which occurs when a small order is placed, in order to encourage compliance with a larger order.
In other words, they visited the apartments in the area of the city where they would like to live and after that visit, they decided to rent one that they liked.
Social Loafing can make moving Kramer and Jerry's belongings to the apartment slower, as this theory is related to less effort in achieving goals when accomplished in a group.
The cerebellum is the part of the brain responsible for coordinating voluntary movement, motor skills, balance and posture, functions that will enable Kramer and Jerry to carry out the work of moving their belongings into the apartment.
The broca's area is the brain area where motor speech is produced, it is responsible for regulating breathing and vocalization during speech, so that communication between them is possible.
Normative social influence occurs when a person adjusts to fit into a group, associated with conformity.
An example of how normative social influence might be related to Kramer and Jerry's life in their new LA apartment could be the set of habits they will acquire while living there, such as physical activity and the use of designer clothing.
Self-fulfilling prophecy corresponds to false expectations about a person or entity, generating adjustments in behavior, perception and communication to match expectations, making it a reality, thus strengthening the belief.
For example, if Jerry and Kramer believe they can't be successful actors in Los Angeles, they skip auditioning to get a role.
