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.

In what ways do cultures use land and resources differently than other cultures?
Answer:
The terms land culture or land-based culture are often used in reference to indigenous cultures that view their responsibility as land curators versus landowners. As such, land is also often connected to the identity and spirituality of individuals within the culture.
Cultures use the environment to their advantage as well as the available livestock, for instance, the incans built long mountainous roads that would make a difficult trek for humans carrying goods, therefore they used llamas, a native animal to the province to carry goods for merchants. This technique was hardly used in other civilizations.

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.

A. It is healthy because any growth rate in the past two years shows a successful economy.
B. It is healthy because any growth rate over −5% is considered positive for a large economy.
C. It is not healthy and contracting because there has been poor growth for two years.
D. It is not healthy and contracting because there was negative growth this year.
Answer:
A
Explanation:
because the economy improvesThe current GDP growth rate tells about the economy that it is healthy because any growth rate in the past two years shows a successful economy. The correct option is A.
What is GDP?Gross domestic product, also known as GDP, is one of the most popular. Gross domestic product "in volume," or assessed at constant prices, is referred to as real gross domestic product (Real GDP).
Thus, price-related changes in GDP (inflation or price declines) are offset, allowing for a measure of economic growth. Nominal GDP continues to be the standard measure for long-term data, and real GDP is only used in practice to gauge GDP growth from year to year.
Therefore, the correct option is A. It is healthy because any growth rate in the past two years shows a successful economy.

to what extent made the natural environment and the demands of pastoral economy influence social organization on Eurasian steppe lands
The social structure of the Eurasian steppe regions was significantly influenced by the natural environment and the needs of the pastoral economy.
The wide grasslands and nomadic way of life in these areas influenced the social structure. Mobility was necessary for nomadic pastoralism to maintain animals, which resulted in social structures that were decentralized and adaptable.
Clan-based kinship networks and tribal ties developed, encouraging cooperation for defense and survival.
Trade routes encouraged cultural interaction and trade, which influenced political federations and alliances.
Because of how important defense and mobility were, leadership was frequently centered around capable military leaders.
Thus, environmental issues in the steppe and the necessity for resource management interacted to create distinct socio-political dynamics that had a lasting impact on governance, migratory patterns, and inter-tribal relations.

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.

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."

Explain why planning and preparation is the best way of reducing the effects of tropical storms (4 Marks)
Answer:
Governments can plan evacuation routes to get people away from storms quickly. Buildings can be designed to withstand tropical storms eg by using reinforced concrete. Buildings can also be put on stilts so they are safe from floodwater Flood defences can be built along rivers (eg levees) and coasts (eg sea walls
Explanation:
Planning and preparation is the best way of reducing the efforts of tropical storms as this helps in reducing the number of buildings which will be destroyed from it.
What are tropical storms?
Tropical storms occur on the Earth in the tropical regions near the equator region. Tropical storms are larger than that of normal storms, however they are not quite as powerful as that of hurricanes. Tropical storms include high wind speeds and heavy rainfall.
Planning the evacuation routes is important as it reduces the number of buildings which will be destroyed with time. Trained people who know what to do which reduces the number of deaths as more people will be rescued from it. Following these routes helps in keeping people away from the floods and debris. So, less people are injured or die.

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.
