How far is Louisville from the nearest oil field?
Answer:
anyywhere between 20-23 miles
Explanation:
it depends what type of oil field u mean
15,499 km is Louisville from the nearest oil field. Therefore, option A is correct.
What do you mean by an oil field ?An oil field is defined as a piece of land beneath which fossil fuels can be extracted for economic value. The world's oil is concentrated in oil fields found in the Middle East, along with other large deposits discovered beneath the ocean's surface.
Oil wells are classified into three different categories. Those that exclusively formed oil, those that exclusively formed natural gas and those that formed both oil and natural gas.
Petroleum supplies transportation fuel, is a part of many chemicals and medicines, and is used to create crucial items such as heart valves, contact lenses, and bandages. Oil reserves attract outside investment and are important for improving countries' overall economy.
Thus, 15,499 km is Louisville from the nearest oil field, option A is correct.

If you get a root canal or any other potentially painful procedure done at the dentist's office, he or she will probably inject your gums with a local anesthetic to "numb the pain." Neurons that trigger pain are called nociceptors. They trigger pain in order to alert the body to potentially dangerous stimuli. Most local anesthetics hinder the activity of all local neurons, not just nociceptors, so pain is not the only sensation that goes away temporarily. Because all feeling is gone, you can end up drooling on yourself without knowing it.
Considering this information about local anesthestics, which of the following statements best demonstrates that science is an ongoing process that changes in response to new information and discoveries?
A. There are a variety of local anesthetics being used today, including lidocaine, prilocaine, and mepivacaine.
B. Sir Charles Sherrington, who discovered nociceptors, wrote a book about the nervous system that helped show its role in allowing organisms to adapt to their environments.
C. Unlike a local anesthetic, a general anesthetic causes a person to lose consciousness rather than sensation in one area.
D. Scientists have discovered a way to use a compound found in hot peppers, capsaicin, along with an anesthetic in order to block nociceptors only.
Which statement BEST describes what happens during solvation?
Answer:
A
Explanation:
The statement best describes solvation " KCl is surrounded by the polar water molecule to form an electrolyte solution which can conduct electricity."
What is solvation?The act of attracting and associating particles of a solvent mostly with molecules as well as ions of a solute would be known as solvation.
What is electrolyte?A material that contains ions and has been electrically conducting due to the mobility of the ions but still doesn't conduct electrons was called an electrolyte.
Whenever the solvent would be in the water, the process is referred to as hydration. The process of solvation shows the combination of solvent and solute molecules. A solute molecule is usually surrounded with solvent molecules that are organized in a special manner during solvation.
Therefore, the correct answer will be an option (A)

WHAT ARE SOME POSSIBLE CONSEQUENCES IF A HUMAN BODY DOES NOT MAINTAIN
HOMEOSTASIS
Answer: If homeostasis is disrupted, it must be controlled or a disease/disorder may result.
Explanation: What happens if there's disruption? Your body systems work together to maintain balance. If that balance is shifted or disrupted and homeostasis is not maintained, the results may not allow normal functioning of the organism.

An object with a mass of 2.0 kg had a force of 4.9 newtons applied to it.What is the resulting acceleration of the object?
This is from my Science Class !And I haven’t seen this question anywhere !
Answer:
2.45 m/s2
Explanation:
Newton's 2nd law tells us that force is equal to the mass of an object multiplied by its acceleration, or F = ma. We can solve this equation for acceleration by rearranging algebraically:
a = F/m
So:
a = (4.9N)/(2.0kg) = 2.45 m/s2

Water is a human necessity. Therefore, it is one of the first things a human settlement would need to have. A community cannot thrive without a water source.
Answer:
Water is a basic need that is more than a necessity, humans can't survive without water for more than a period of three days, And thus having water as available, creates a tendency among humans as humans like to get everything at ease so they tend to settle near the water bodies if possible.
An object accelerates 5.0 m/s2 when a force of 12.0 newtons applied to it.What is the mass of the object?
Please help, I haven’t seen this question anywhere !
Also this is from my Science Class
Answer:
2.4kg
Explanation:
Newton's 2nd law tells us that force is equal to the mass of an object multiplied by its acceleration, or F = ma. We can solve this equation for mass by rearranging algebraically:
m = F/a
So:
m = (12.0N)/(5.0m/s2) = 2.4kg

hi can you balance the equation Fe + O2 = Fe2O3
Answer:
4Fe + 3O2→ 2Fe2O3
Explanation:
Fe + O2 → Fe2O3 is the unbalanced form of chemical reaction.
Balancing the simple molecules first, in this case the O2
Fe + 3O2→ Fe2O3 there are now 6 O atoms on the left, there must also be 6 O atoms on the right.
Fe + 3O2 → 2Fe2O3
Balance the rest of the equation.
4Fe + 3O2→ 2Fe2O3
