How does the Hubble space telescope work?
Space and AstronomyThe Hubble is a reflecting telescope. It gathers light emanating from celestial objects with its large 2.4-meter primary mirror, and reflects the light toward its secondary mirror. This mirror focuses the light onto scientific instruments like cameras and spectrographs. How does the Hubble telescope stay in space? While operating in Earth orbit, the Hubble Space

What is a circle in algebra?
Space and AstronomyIn algebraic terms, a circle is the figure formed by the set (or “locus”) of points (x, y) at some fixed distance r from some fixed point (h, k). The value of r is called the “radius” of the circle, and the point (h, k) is called the “center” of the circle. What is a

What is supplementary and complementary?
Space and AstronomyTwo angles are called complementary when their measures add to 90 degrees. Two angles are called supplementary when their measures add up to 180 degrees. What is supplementary and example? If sum of two angles is 180°, they are supplementary. For example. 60° + 120° = 180° Since, sum of both angles is 180° So,

What is the slope of a perpendicular bisector?
Space and AstronomyThe slope of the perpendicular bisector = -1/slope of the line. What is the slope of perpendicular lines? negative reciprocals Perpendicular lines have slopes that are negative reciprocals of one another. The given line’s slope is 5, which means that the slope of the other line must be its negative reciprocal. What is the perpendicular
