The mountain peak of Chimborazo is the farthest from the center of the earth. Chimborazo is 2.1 kilometers farther from the Earth's center compared to Everest.
The Titan Atlas.
To calculate the weight of a person on the Moon, we need to divide their weight on Earth by 6. This means that a person weighing 183 lb on Earth would weigh approximately 30.5 lb on the Moon. This calculation is based on the Moon's gravity being about 1/6th that of Earth's.
Early astronomers called this an "epicycle"; a whirling circle whose center was traveling in a larger circle. They used this to try to explain the observed motions of the planets, because Aristotle said that all motion in the heavens was circular, and so ellipses were right out!
I think you mean, :why does the orbit of satellites, etc. look like a sine wave? Well, every orbit around the earth looks like a circular (or elliptical ring) whose center (or focus) is at the center of the earth. An orbit exactly above the equator is one such orbit, but any orbit can be tilted as long as the center (or focus) stays at the earth's center and the whole orbit is flat like a disk. On various maps this makes the orbit look like a wave, but on a globe it stays a flat circle (or ellipse).
The geocentric model, also known as the Ptolemaic system, held for over a thousand years. It was standardized by the Greek astronomer Ptolemy. Based on his model, the Earth was at the center of the universe and the sun and planets revolved around it. It was the accepted model up until the 1500's when Copernicus put forth is heliocentric model, one that placed the sun at the center and the planets in orbit or it.
Any circle on the Earth's surface whose center is at the center of the Earth is called a "great circle". Any circle with its center anywhere else is called a "small circle". Spiritually, many consider the kaaba (Mecca) to be the center of the Earth's surface.
The country whose capital is the furthest north is Iceland. Reykjavik, the capital of Iceland, is the northernmost capital city in the world.
The weight of an object is its mass times the acceleration of gravity. The acceleration of gravity at the center of the Earth is zero. A 1 kg mass at the center of the Earth still has a mass of 1 kg, but the force of attraction between the 1kg mass and all the other mass around it will add up to zero.
One kilogram. Mass is invariant.The weight at that point is zero. But the mass doesn't change.
Claudius Ptolemy's (wrong) theory with the Earth at the center of the universe lasted for more than 1000 years
-- The 'great circle' route is the shortest distance between any two places on Earth (or on any other sphere). -- A great circle is a circle on the surface whose center is at the center of the Earth. -- The phrase "around the globe" is really not too clear.
That's a "central angle", but the part that really fascinates me is this: What would it look like if you hadan angle whose vertex was in the center of the circle and whose sides didn't intersect ? ? ?
x2 + y2 = 2
It will be the same angle subtended by its circumference.
The Catholic Church held that the Earth was the center of the universe and all other planets and the sun revolved around the Earth. They did put to death those who insisted otherwise.
Hearing center whose cells connect with the brain is known as the spiral ganglion. This is what will facilitate all audio signal transmission.
That is the central angle.
