What is the focal width of a parabola?
Space and AstronomyFocal Width The focal width of a parabola is the length of the focal chord, that is, the line segment through the focus perpendicular to the axis, with endpoints on the parabola. How do you find the focal width of a parabola? To find the focal point of a parabola, follow these steps: Step 1:
How a Galilean telescope works?
Space and AstronomyIn Galileo’s version, light entering the far end (1) passed through a convex lens (2), which bent the light rays until they came into focus at the focal point (f). The eyepiece (3) then spread out (magnified) the light so that it covered a large portion the viewer’s retina and thus made the image appear
How was Earth created?
Space and AstronomyWhen the solar system settled into its current layout about 4.5 billion years ago, Earth formed when gravity pulled swirling gas and dust in to become the third planet from the Sun.

The Graphics’ industry standard is width by height (width x height). Meaning that when you write your measurements, you write them from your point of view,
How do you graph Cartesian product?
Space and AstronomyHow do you find the Cartesian product of two graphs? Definition 1.2 [1] Let G1 = (V1,E1) and G2 = (V2,E2) be two simple connected graphs. The Cartesian product G1 ×G2 of G1 and G2, is a graph with vertex set V = V1 × V2 and two vertices (u, v) and (u′,v′) in V
