Why do single dish radio telescopes have poor resolution?
Space and AstronomyWhy do single-dish radio telescopes have poor resolving power compared to optical telescopes of the same diameter? Because the size of diffraction fringes is proportional to the wavelength of light being focused, and radio waves have longer wavelengths than visible light. Why do radio telescopes have low resolution? . Radio waves have a large wavelength
Why is a rational function not a polynomial?
Space and AstronomyAny rational function r(x) = , where q(x) is not the zero polynomial. Because by definition a rational function may have a variable in its denominator, the domain and range of rational functions do not usually contain all the real numbers. Is a rational function a polynomial? Just as rational numbers are defined in terms
What is stellar parallax and how do astronomers use it?
Space and AstronomyAstronomers use an effect called parallax to measure distances to nearby stars. Parallax is the apparent displacement of an object because of a change in the observer’s point of view. What is stellar parallax and how do astronomers use it quizlet? What is Stellar parallax? It is the slight back-and-forth shifting of star positions that
What is Euler path and circuit?
Space and AstronomyAn Euler path is a path that uses every edge of a graph exactly once. An Euler circuit is a circuit that uses every edge of a graph exactly once. ▶ An Euler path starts and ends at different vertices. What is a Euler path example? One example of an Euler circuit for this graph
How did Katherine Johnson first husband die?
Space and Astronomybrain cancerbrain cancer in 1956, leaving her, at 38, a widow with three adolescent daughters. She married James A. What happened to Katherine’s husband in hidden figures? She spent the next four years analyzing data from flight tests and worked on the investigation of a plane crash caused by wake turbulence. As she was wrapping
How do you state if the triangles in each pair are similar?
Space and AstronomyHow do you determine if the triangles in each pair are similar? If two pairs of corresponding angles in a pair of triangles are congruent, then the triangles are similar. We know this because if two angle pairs are the same, then the third pair must also be equal. What are the 3 ways to

How do solar winds work?
Space and AstronomyThe solar wind is created by the outward expansion of plasma (a collection of charged particles) from the Sun’s corona (outermost atmosphere). This plasma is continually heated to the point that the Sun’s gravity can’t hold it down. It then travels along the Sun’s magnetic field lines that extend radially outward. What are solar winds
Is a counterclockwise rotation positive or negative?
Space and AstronomyThe measure of an angle describes the magnitude and direction of the rotation of the ray from its initial position to its terminal position. If the rotation is counterclockwise, the angle has a positive measure. If the rotation is clockwise, the angle has a negative measure. Is a rotation counterclockwise negative? Clockwise Rotations (CW) follow
