How moon becomes half and full?
Space and AstronomyFirst of all, the moon revolves around the Earth once every 29.5 days. And secondly, as the moon carries out its voyage around the planet, it’s lit from varying angles by the sun. When the moon and the sun are on opposite sides of the Earth, we perceive the moon as full. How does the
Why do my brakes keep seizing?
Space and AstronomyTypically, seizing will occur when your vehicle is not in frequent use. The main reason for this is because when you brake, the moisture on your discs are usually cleared away. Generally, you can tell when your brake calipers need replacing when you notice that your brake pads have worn down excessively. How do I

Why are refracting telescopes no longer used?
Space and AstronomyLimitations of Refracting Telescopes Lenses create a type of image distortion known as chromatic aberration. This occurs because as light passes through a lens, different colors are bent through different angles (like in a prism) and brought to a focus at different points. Are refracting telescopes still used? Although large refracting telescopes were very popular

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
How do you make a telescope for a science project?
Space and AstronomyWhat You Do: Roll up the sheet of paper or cardstock the long way to form a tube that is about the diameter of the lens with the shortest focal length. … Tape the second lens neatly to the end of the paper towel tube. … Look through the eyepiece and point the other end
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 are the asteroid belts in our solar system?
Space and AstronomyThe asteroid belt is a torus-shaped region in the Solar System, located roughly between the orbits of the planets Jupiter and Mars. It contains a great many solid, irregularly shaped bodies, of many sizes, but much smaller than planets, called asteroids or minor planets. What are the two asteroid belts in our solar system? The
