The truse shape of planetary orbits was discovered by who?
The true shape of planetary orbits was discovered by Johannes Kepler in the early 17th century. He formulated three empirical laws, now known as Kepler's Laws of Planetary Motion, which describe the motion of planets in the Solar System. These laws are as follows: The orbit of each planet is an ellipse with the Sun at one of the two foci. A line joining a planet and the Sun sweeps out equal areas during equal intervals of time. The square of the orbital period of a planet is proportional to the cube of the semi-major axis of its orbit.Kepler's Laws of Planetary Motion provide a mathematical description of the motion of planets in the Solar System and explain why planets move in elliptical orbits around the Sun.
Who created stars?
The Babylonians in about 700 BC used numbers to describe angles, and divided a circle into 360 equal degrees for that purpose, then angles were described in degrees. Using that they were able to record the positions of stars.
What are the three fundamental laws of planetary motion which describe the copernican theory?
There are no fundamental laws behind the Copernican theory. The three laws of planetary motion that we use now were discovered by Johannes Kepler and published in 1609, sixty-six years after Copernicus died. Kepler introduced the new idea of elliptical orbits. The idea that the Sun is at the centre (loosely speaking) was the only part of the Copernican theory that Kepler retained.
Who wrote the theory for the gravitational laws of planetary motion?
There are numerous theories of planetary motion. Ptolemaeus (earth in the centre), Copernicus (the sun in the centre, planets orbit around it), Kepler (planet orbits are ellipses) all wrote such theories.
When astronomers study distant galaxies they notice changes to the waves they observe describe the change to the waves they observe?
Because the universe as a whole is expanding, distant galaxies are moving away from us. As a result, electromagnetic waves emitted by those galaxies experience what is known as a red shift. Their wavelengths get longer.
Describe the planetary model of an atom?
The planetary model of an atom is simple. The nucleus is the planet and the electrons are the moons in the model.
How do you describe fully a single transformation in maths?
It depends on the kind of transformation.
Does not describe a rigid motion transformation?
Stretch
Describe the terrible transformation that Africans experienced because of the Maafa?
The Maafa refers to the transatlantic slave trade that resulted in Africans being forcibly taken from their homeland, enduring brutal conditions during the Middle Passage, and being subjected to dehumanizing treatment as slaves in the Americas. This resulted in the loss of lives, culture, and generational trauma for African descendants.
Describe two uses of expanding lquids?
thermometer and car radiator
Words that describe clouds ending in ing?
Traveling, expanding, and forming :)
Describe literature in three words?
words written down words expanding world, or possibly: world expanding words
Can you describe the transformation using coordinate notation?
A transformation using coordinate notation involves applying a specific set of rules to the coordinates of points in a geometric figure to create a new figure. This is often represented as (x, y) → (x', y') where the prime (') denotes the new coordinates after the transformation has been applied. The specific rules can include translations, rotations, reflections, or scaling.
Which word best describes the reaction of dr lanyon to the transformation of mr hyde-?
Words that best describe the reaction of Dr. Lanyon to the transformation of Mr. Hyde include: Despair Horrified
Describe the energy transformation that occurs as fuel is used by engine of a car?
chemical energy is converted to kinetic energy
An eagle flies from its perch in a tree to the ground describe the energy transformation?
Mechanical energy. It has both potential and kinetic energy.
How do you describe a transfermation that maps an equilateral triangle onto itself for translation?
For translation, the only transformation (not transfermation), is the null translation (0,0).
