Answer:
Newton
Explanation:
Ptolemy usually talked about "Earth-centered," or "geocentric" theory that all celestial objects — including the planets, Sun, Moon, and stars — orbited Earth. Earth, in the center of the universe, did not move at all and obviously this theory has been proven wrong.
Brahe model had all the planets (except Earth) orbiting around the Sun, but then the Sun orbited around the Earth. This is also a wrong concept.
Kepler's Laws are mostly based upon the Planetary Motion and are incomplete is some areas.
Only Newton law best describes the motion of all planets where he says that all motion, whether it was the orbit of the Moon around the Earth or an apple falling from a tree, followed the same basic principles.
Johannes Kepler, assisted by Tycho Brahe's observations, provided the first simple and accurate description of Earth's motion, forming the basis for Newton's gravitational laws.
Understanding the Motion of Earth
When it comes to describing the motion of the Earth, Johannes Kepler would be the scientist that comes to mind. Kepler, along with the observations of Tycho Brahe, developed the first simple and accurate description of how planets move, including the Earth. Their work was foundational for the later developments by Isaac Newton in formulating the laws of gravitation, which not only explained the motion of celestial bodies but also tied it to the motion of objects falling to Earth. Kepler's laws accurately describe the elliptical orbits of planets, a significant advance from the epicycles of Ptolemy, which were circles within circles.
While Kepler's work was based on the heliocentric theory, which places the Sun at the center of the solar system as suggested by Nicolaus Copernicus, Ptolemy's model was geocentric, placing Earth at the center. The work of Kepler and Brahe was crucial in overthrowing Ptolemy's system and setting the stage for Newton's unification of celestial and terrestrial mechanics.

David has a piece of wood measuring 1218 feet that he wants to use for a project. He needs to cut the wood into pieces that measure 11316 feet. How many pieces of wood can he cut measuring exactly 11316 feet?
David can cut 10 whole pieces of wood measuring exactly 11316 feet from a piece of wood measuring 1218 feet after converting both measurements to inches and dividing the total length by the piece length.
Explanation:Calculating Pieces of Cut WoodTo answer the question: David has a piece of wood measuring 1218 feet that he needs to cut into pieces measuring 11316 feet each. To determine how many pieces he can cut, it is necessary to convert both measurements to a common unit, such as inches, and then divide the total number of inches in the wood by the number of inches in the pieces he wants to cut.
First, convert 1218 feet to inches: (12 feet × 12 inches/foot) + (18 inches) = 144 inches + 18 inches = 162 inches. Next, convert 11316 feet to inches: (1 foot × 12 inches/foot) + (316 inches) = 12 inches + 3.75 inches = 15.75 inches. Now divide the total number of inches in the wood by the number of inches each piece should be: 162 inches ÷ 15.75 inches. The result is approximately 10.29.
Since David can't cut a fraction of a piece, he can only cut 10 whole pieces of wood measuring exactly 11316 feet.

Each region contains its own unique vegetation, land features, and soil types.
What do you understand about vegetation?Vegetation is an assemblage of plant species and the ground cover they provide. It is a general term, without specific reference to particular taxa, life forms, structure, spatial extent, or any other specific botanical or geographic characteristics. It is broader than the term flora which refers to species composition.
Perhaps the closest synonym is plant community, but vegetation can, and often does, refer to a wider range of spatial scales than that term does, including scales as large as the global. Primeval redwood forests, coastal mangrove stands, sphagnum bogs, desert soil crusts, roadside weed patches, wheat fields, cultivated gardens and lawns; all are encompassed by the term vegetation.
The vegetation type is defined by characteristic dominant species, or a common aspect of the assemblage, such as an elevation range or environmental commonality.

If it is 5 am where you are and 7:30 pm GMT, what is your longitude
To determine the longitude based on different time zones, calculate the difference in time, which corresponds to the longitude difference.
Explanation:The question asks about determining longitude based on different time zones. When it is 5 am in the student's location and 7:30 pm GMT, we can calculate the difference in time to determine the longitude. Since each time zone is 15 degrees wide, the difference in time corresponds to the longitude difference. For example, if the student's location is ahead by 14.5 hours (which is 22.5 degrees), then the longitude would be 22.5 degrees east.

Why have corporations in the United States outsourced communication jobs to countries such as India?
A) no labor restrictions in India
B) availability of cheap labor in India
C) availability of native English speakers
D) loss of jobs in the US of native speakers of English
US corporations outsource jobs to India because of the country's low labor costs and large, educated, English-speaking workforce, which makes it an efficient and cost-effective outsourcing destination within a globalized trade environment.
Explanation:Corporations in the United States have outsourced communication jobs to countries like India primarily due to the availability of cheap labor. Labour costs in India are significantly lower than in the US, which makes it financially beneficial for companies looking to reduce expenses. Additionally, India offers a large pool of educated individuals who are fluent in English, making it an ideal location for customer service and technical support roles that require proficiency in the language.
Another factor contributing to outsourcing is that India has a high number of skilled or educated workers who can be trained for service-industry tasks. This skilled labor base coupled with high-speed communication links, enables efficient and cost-effective outsourcing for US companies. Furthermore, the trend of globalization has made outsourcing more common, with trade agreements facilitating international business and companies seeking to maximize profits by reducing costs.

His mistake is that he has already covered 2 laps but did not include them.
What are ratio and proportion?A ratio is a collection of ordered integers a and b represented as a/b, with b never equaling zero. A proportionate expression is one in which two items are equal.
Blake ran around the gym.
His times are shown in the table.
Blake is trying to decide whether the number of laps is proportional to the time.
The time T is directly proportional to the number of laps N.
N ∝ T
If the sign of proportionality is replaced with an equal sign, then a constant k is introduced.
N = kT
Then the value of k will be
N = 2T
But the equation is not satisfied. So add 2 on the right side, then we have
N = 2T + 2

Suggest a reason that the time zone do not exactly follow meridians
Final answer:
Time zones do not follow meridians exactly because doing so would split regions into different zones causing inconvenience and administrative challenges. Therefore, time zone boundaries often zigzag to align with political or natural boundaries, with some countries like China choosing to operate under a single time zone for simplicity and unity.
Explanation:
Time zones do not exactly follow meridians due to practical considerations related to state, regional, and local boundaries. For example, in the United States, time zone boundaries zigzag to ensure that an entire city or state falls within the same time zone. This avoids confusion and inconvenience, as well as helps with economic and social unity within distinct regions.
China, in contrast to the segmented time zones of the United States, has chosen to use a single time zone across the whole country, even though its land area spans several conventional time zones. This centralization is also rooted in administrative efficiency and national unity.
The original concept, as proposed by Sir Sanford Fleming in 1878, was to have 24 time zones each 15 degrees of longitude apart, which would correspond to one-hour increments based on Earth's rotation. However, keeping to such a rigid system would require constant readjustment of time with every minor movement east or west. To address this issue, time zones were broadened to strips roughly 15 degrees wide but adjusted to accommodate human activity and governance.

Hurricanes vs tornadoes
Final answer:
Hurricanes develop over warm water, while tornadoes come out of severe thunderstorms.
Explanation:
Hurricanes develop over water that is warmer than 80 °F. As the air heats, it rises rapidly, drawing incoming air to replace the rising air and creating strong wind currents and storm conditions. The rapidly rising humid air then cools and condenses, resulting in heavy rains and a downdraft of cooler air. The rotation of the earth causes the storm to rotate in a cyclonic pattern. North of the equator, tropical storms rotate in a counterclockwise direction. South of the equator, tropical storms rotate in a clockwise direction.
Tornadoes come out of severe thunderstorms called supercells, which have a column of air rotating around a horizontal axis. The difference in wind speeds between the strong cold winds higher up in the atmosphere and weaker winds traveling north from the Gulf of Mexico causes the column of rotating air to shift so that it spins around a vertical axis, creating a tornado.
