What is the difference between an isosceles trapezoid and a trapezoid?
Space and AstronomyA trapezoid is a quadrilateral where one pair of sides is parallel while the other two sides are not. In an isosceles trapezoid the non-parallel sides are congruent. How do you know if it’s an isosceles trapezoid? A trapezoid is isosceles if and only if its diagonals are congruent. So if we can prove that
Why is the eccentricity of parabola 1?
Space and AstronomyEccentricity of Parabola In other words, the distance from the fixed point in a plane bears a constant ratio equal to the distance from the fixed-line in a plane. Therefore, the eccentricity of the parabola is equal 1, i.e. e = 1. What does it mean if eccentricity is 1? parabola If the eccentricity is
How were the smooth dark plains called maria formed on the moon’s surface?
Space and AstronomyThe maria basins were formed beginning about 3.9 billion years ago during a period of intense bombardment by asteroid-sized bodies. This was well after the lunar crust had cooled and solidified enough, following the Moon’s formation, to retain large impact scars. How were the very smooth dark plains called the maria formed on the Moon’s
What is Union find algorithm explain with an example?
Space and AstronomyA union-find algorithm is an algorithm that performs two useful operations on such a data structure: Find: Determine which subset a particular element is in. This can be used for determining if two elements are in the same subset. Union: Join two subsets into a single subset. What is Union-Find in Python? Union-Find is a
What colors do calla lilies come in?
Space and AstronomyCalla lilies are easy to grow and add a classy look to perennial gardens, cutting gardens and container plantings. Their distinctive flowers come in many beautiful colors, including classic white (a favorite for weddings), yellow, orange, pink, rose, lavender and dark maroon. How many colors do calla lilies come in? There are seven different species.
What does drinking Moon Water do?
Space and AstronomyWhat is drinking moon water Good For? Halley says that a moon water ritual can help you to feel in “flow” with the universe. “It benefits spiritual practice in many ways by allowing us to energetically supercharge our life source, water, with an energy source, the moon, that’s so powerful it pushes and pulls the
What observational evidence confirms that tidal heating is important on Io?
Space and AstronomyWhat observational evidence confirms that tidal heating is important on Io? active volcanoes on Io. Orbital resonance also gives Europa an elliptical orbit, so it experiences tidal heating, too. Why does Io experiences strong internal tidal heating? Tidal heating of Io (also known as tidal working) occurs through the tidal friction processes between Jupiter and
What would living on Venus be like?
Space and AstronomyThe temperature on the surface of Venus is exceptionally hot, and no life could survive there. But it is thought the planet was once cooler and wetter, with conditions that may have allowed life to start more easily. Scientists found the phosphine gas in the acidic clouds floating above the planet. How would it be
Which classical orbital element describes the orbit size?
Space and AstronomyThe eccentricity, e, and either the semi-major axis, a, or the distance of periapsis, q, are used to specify the shape and size of an orbit. Which classical orbital element tells us about the size of the orbit? semi-major axis The classical orbital elements are: a: semi-major axis, gives the size of the orbit. What
What are the three stages of crater formation?
Space and AstronomyFor simplicity, we can split the formation of a crater into 3 stages: contact and compression, excavation, and modification. What are the three types of crater forms? Lunar impact craters come in three basic types: simple craters, complex craters, and basins. Simple craters are what most people think of when they visualize a crater. They
