Answer:
The volume of air needed is 603 cm³.
Explanation:
In general, basketball has a size of a sphere, so you have to find the volume of sphere using the formula :
[tex]v = \frac{4}{3} \pi {r}^{2} [/tex]
[tex]let \: r = 12[/tex]
[tex]v = \frac{4}{3} \times \pi \times {12}^{2} [/tex]
[tex]v = \frac{4}{3} \times \pi \times 144[/tex]
[tex]v = 192\pi[/tex]
[tex]v = 603 \: {cm}^{3} (near. \: whole \: no)[/tex]

Answer: Raymond Wang: How germs travel on planes – and how we can stop them
1. After completing the unit and watching the video, explain how the unit about oceans and the video about germs on a plane relate?
In his video Raymond explains how the diseases are transmitted through planes from one country to another and the difficulties faced to prevent the spread of diseases due to the air circulation in the planes. It is always difficult to screen the person with disease and prevent them from getting into the plane since the air circulates in the conventional cabins. When a person sneezes, the air will get swirled multiple times and spread the disease.
2. Using examples from the video, explain why it is difficult to keep people who are sick off of planes.
It’s difficult to pre-screen for diseases. When someone goes on a plane, they could be sick and actually be in this latency period in which they could have the disease but not exhibit any symptoms and could possibly spread the disease to many other people.
3. How does Wang illustrate what happens in a conventional airplane cabin when someone sneezes?
He illustrates how the air is just being circulated throughout the plane. When someone sneezes, the air is just being circulated into the air. This means that everyone on that plane has breathed in that person’s sneeze because it’s such a compact place.
Answer:
1. The air circulates in the cabins so when a person sneezes the air will get swirled around multiple times and spread the disease.
2. Many diseases like sars, don't show up on simple testings and the person could have a disease early on and it would be nearly impossible to identify.
3. He illustrates how the air is being circulated throughout the plane. When someone sneezes, the contaminated air is being circulated throughout the plane. This means that everyone on that plane has breathed in that person’s sneeze because it’s so compact.
4. Wang’s invention can stop the spread of disease because it pushes all of the air down meaning if someone coughed or sneezed, instead of spreading around the cabin, the air would get pushed down to the filtration system before reaching multiple people. The word “flow” has to do with his solution because he is redirecting the flow of the air in the airplane downwards to prevent more people from getting sick.

You are 10°N and 30°E; you move to a new location that is 25° south and 40° west of your present location. What is your new latitude and longitude position?
If we are 10'N and 30°E and we move to a new location that is 25 south and 40" west of our present location. Our new latitude and longitude position will be 15' south 10 "west latitude and longitude.
What is longitude?Longitude is a geographic coordinate that specifies the east–west position of a point on the surface of the Earth, or another celestial body. It is an angular measurement, usually expressed in degrees and denoted by the Greek letter lambda. Meridians are semicircular lines running from pole to pole that connects points with the same longitude.
The prime meridian defines as 0° longitude; by convention, the International Reference Meridian for the Earth passes near the Royal Observatory in Greenwich, England on the island of Great Britain. Positive longitudes are east of the prime meridian, and negative ones are west. Because of the Earth's rotation, there is a close connection between longitude and time measurement.
Scientifically precise local time varies with longitude: a difference of 15° longitude corresponds to a one-hour difference in local time, due to the different positions about the Sun.

For approximately how many thousands of years has the Earth been in the peak of an inter-glacial period within the present ice age?
Answer: The glacial-interglacial cycle is triggered by changes in Earth's orbit around the Sun, and, as a result, there is approximately 100,000 years between interglacials (or glacials).
Explanation:
Within the present Ice age, the earth has been at the peak of an interglacial period for approximately 100,000 years.
What is the Ice age?The ice age which is also called the glacial age is any geologic period during which thick ice sheets cover vast areas of land. Periods like this have large-scale glaciation which may last several million years and dramatically reshape the surface features of entire continents.
A major number of ice ages have occurred throughout earth's history. During Precambrian time dating back more than 570 million years, the earlier ice age took place. And the most recent took place during the Pleistocene Epoch which us 2.6 million to 11,700 years ago.
The lesser recent glacial stage called the Little Ice Age began in the 16th century. It advanced and receded intermittently over 3 centuries in Europe and many other regions.
The ice age lasted until 11,500 years ago.

Geology (lithosphere):
How does it behave as a system?
Answer:
Explanation:
Geography doesn't just determine whether humans can live in a certain area or not, it also determines people's lifestyles, as they adapt to the available food and climate patterns. As humans have migrated across the planet, they have had to adapt to all the changing conditions they were exposed to.
Everything is influenced by geography, including our social and economic structures as well as our food, health, and safety. Systems are made up of parts and processes, which form their structure. Systematizations of reality are called systems.
What is physical geography?One of geography's three basic subfields is physical geography. Physical geography is a discipline of study that investigates the structures and processes that happen in the natural world.
The mobility, transformations, and mechanisms of the globe can be better understood through geography. The resources and limitations that define much of human influence are provided by physical geography, which has an effect on human growth and population.
Systems can be isolated, closed, or one of the three. Mass and energy can move freely within and outside of open systems. A closed system's system boundary enables the transfer of electricity but not of mass.

A weather map, commonly referred to as a synoptic weather chart, shows different meteorological features across a certain area at a particular time and contains different symbols with different meanings.
What is Weather Map ?From the middle of the 19th century, these maps have been utilised for research and weather forecasting.
Isothermal maps display temperature gradients that can be used to identify weather fronts. The location of the jet stream is shown using isotach maps, which analyse lines of equal wind speed over a surface of constant pressure of 300 or 250 hPa.
Tropical cyclone motion can be determined by using constant pressure charts at the 700 and 500 hPa levels.
The surface weather analysis, which depicts isobars to show areas of high atmospheric pressure, is a popular type of surface weather map low and high pressure.
These maps display the cloud codes, which are converted into symbols and shown alongside other meteorological information from synoptic reports given by skilled observers.

The linear parent function is transformed to create the new function g(x)=12f(x−13). What is the correct description of the transformations.
The new function g(x) is less steep than f(x) and shifted to the left 13 units.
The new function g of x is less steep than f of x and shifted to the left 13 units.
The new function g(x) is steeper than f(x) and shifted to the left 13 units.
The new function g of x is steeper than f of x and shifted to the left 13 units.
The new function g(x) is steeper than f(x) and shifted to the right 13 units.
The new function g of x is steeper than f of x and shifted to the right 13 units.
The new function g(x) is less steep than f(x) and shifted to the right 13 units
Answer:
The new function g(x) is steeper than f(x) and shifted to the left 13 units.
Explanation:
Given
[tex]g(x) = 12f(x - 13)[/tex]
Required
Determine the relationship between f(x) and g(x)
First, we need to determine the direction which f(x) is shifted to (right or left)
For a function f(x)
f(x - h) implies that f(x) is shifted right by h units
So, f(x - 13) implies that f(x) is shifted right by 13 units
Next, we determine the steepness of f(x) and g(x)
We can assume that the steepness of f(x) is 1
The steepness of g(x) can be determined as follows:
[tex]g(x) = 12f(x - 13)[/tex]
[tex]g(x) = 12 * f(x - 13)[/tex]
Hence, the steepness of g(x) is 12
Going by the analysis above:
g(x) is steeper and f(x) is shifted 13 units right to get g(x)
