What is the condensation theory of solar system formation?
Space and AstronomyThe condensation theory of the solar system explains why the planets are arranged in a circular, flat orbit around the sun, why they all orbit in the same direction around the sun, and why some planets are made up primarily of rock with relatively thin atmospheres. What is the condensation sequence theory? In planetary science,

What is the mean value theorem for derivatives?
Space and AstronomyThe Mean Value Theorem states that if a function f is continuous on the closed interval [a,b] and differentiable on the open interval (a,b), then there exists a point c in the interval (a,b) such that f'(c) is equal to the function’s average rate of change over [a,b]. What is the Mean Value Theorem used

What is the purpose of a Mobius strip?
Space and AstronomyMöbius strips appear in molecules and devices with novel electrical and electromechanical properties, and have been used to prove impossibility results in social choice theory. In popular culture, Möbius strips appear in artworks by M. C. Escher, Max Bill, and others, and in the design of the recycling symbol. What is so special about the

What is the meaning of Deimos and Phobos?
Space and AstronomyPhobos and Deimos (moons of Mars) Mars has two small moons: Phobos and Deimos. Phobos (fear) and Deimos (panic) were named after the horses that pulled the chariot of the Greek war god Ares, the counterpart to the Roman war god Mars.

What are alternate angles on parallel lines?
Space and AstronomyAlternate angles are angles that occur on opposite sides of the transversal line and have the same size. Each pair of alternate angles around the transversal are equal to each other. The two angles can either be alternate interior angles or alternate exterior angles. How do you find alternate angles in parallel lines? Video quote:

How much does the moon mass?
Space and Astronomy7.35 x 1022 kgMoon mass, density and gravity The moon’s mass is 7.35 x 1022 kg, about 1.2% of Earth’s mass. Put another way, Earth weighs 81 times more than the moon. The moon’s density is 3.34 grams per cubic centimeter (3.34 g/cm3). That is about 60% of Earth’s density. How much mass is in
