What evidence can you give that the solar corona is at a very high temperature?
Space and AstronomyWhat is a possible explanation for the high temperature of the solar corona? What is a possible explanation for the high temperature of the solar corona? Magnetic field waves from the Sun cause particles to move faster. Which of the following statements about the sunspot cycle is true? How do we know the corona of

Which functions have a vertex?
Space and AstronomyOne of the common forms for quadratic functions is called vertex form, because it highlights the coordinates of the vertex of the function’s graph. How do you know if a function is in vertex form? If a parabola opens upward, it has a lowest point. If a parabola opens downward, it has a highest point.

How do you read a second derivative graph?
Space and AstronomyThis is read aloud as “the second derivative of f. If f″(x) is positive on an interval, the graph of y = f(x) is concave up on that interval. We can say that f is increasing (or decreasing) at an increasing rate. If f″(x) is negative on an interval, the graph of y = f(x)

What satellites are visible from Earth?
Space and AstronomyThe two undisputed rock stars of satellite spotting are the Hubble Space Telescope and the International Space Station (ISS), the largest manmade object in Earth orbit. When the position of the sun and the orbit of these satellites are just right, they can easily be seen. The ISS can appear as bright as Venus. Can

What is a space rock called?
Space and AstronomyAsteroids are sometimes called space rocks. Meteorites are also sometimes called space rocks. What do you call a piece of space rock? Meteoroids Meteoroids are fragments and debris in space resulting from collisions among asteroids, comets, moons and planets. They are among the smallest “space rocks.” However, we can actually see them when they streak

What is the definition of segment addition postulate in geometry?
Space and AstronomyIn geometry, the Segment Addition Postulate states that given 2 points A and C, a third point B lies on the line segment AC if and only if the distances between the points satisfy the equation AB + BC = AC. What is an example of segment addition postulate? According to the segment addition postulate,

What is the perpendicular of 2?
Space and AstronomyWhat is the perpendicular lines of 2? If two non-vertical lines in the same plane intersect at a right angle then they are said to be perpendicular. Horizontal and vertical lines are perpendicular to each other i.e. the axes of the coordinate plane. The slopes of two perpendicular lines are negative reciprocals. What is perpendicular

Why are most telescopes reflectors not refractors?
Space and AstronomyWhy are most large telescopes reflectors, not refractors? A. Reflectors do not suffer from chromatic aberration like refractors do. Why are most research telescopes reflectors rather than refractors? The most. The main reason that most professional research telescopes are reflectors is that: Large mirrors are easier to build than large lenses. Which design was a

How is temperature measured in Spain?
Space and AstronomyHow do you measure temperature in Spanish? Converting between these two measurements of temperature can get a little tricky since a degree Celsius and a degree Fahrenheit scale differently.28° in Summer. °C Spanish Pronunciation Converted into °F 0°C cero grados centígrados 32°F 10°C diez grados centígrados 50°F 16°C dieciséis grados centígrados 60°F What temperature scale

How do you prove equal chords of a circle are equidistant from the Centre?
Space and AstronomyWhy are equal chords equidistant from the centre? The line OX is perpendicular to the chord AB and OY is perpendicular to the chord CD. We have to prove OX = OY. Also, the line OX is perpendicular to AB. Therefore, the theorem “equal chords of a circle (or of congruent circles) are equidistant from
