Is the world’s largest telescope reflecting or refracting?
Space and AstronomyThe largest refracting telescope in the world is the Yerkes Observatory 40 inch (102 cm) refractor, used for astronomical and scientific observation for over a century. Are large telescopes refracting or reflecting? Reflecting telescopes have a large mirror that has more light collecting capacity whereas refracting telescopes have a small diameter that has less light

What is circle and its parts?
Space and AstronomyThe 4 main parts of a circle are radius, diameter, center, and circumference. The center of the circle is the point that is equidistant from all the sides of the circle. What are the parts of circle? The diameter cuts the circle exactly in half and goes through the centre. The radius is half the

What causes the cycle in solar activity?
Space and AstronomyThe solar cycle affects activity on the surface of the Sun, such as sunspots which are caused by the Sun’s magnetic fields. As the magnetic fields change, so does the amount of activity on the Sun’s surface. One way to track the solar cycle is by counting the number of sunspots. What causes solar cycle?

How do you make a half dome in Sketchup?
Space and AstronomyHow do you make a dome shape in SketchUp? Video quote: And i'm going to start by drawing a circle okay so this is going to be the bottom of our dome. What we then want to do is we want to draw. Or use the two point arc tool like that. And we want

How do you do linear transformations using matrices?
Space and AstronomyA plane transformation F is linear if either of the following equivalent conditions holds: F(x,y)=(ax+by,cx+dy) for some real a,b,c,d. That is, F arises from a matrix. For any scalar c and vectors v,w, F(cv)=cF(v) and F(v+w)=F(v)+F(w). How do you do linear transformation matrix? Video quote: Multiply. Them by the corresponding columns of the matrix. Then

Why is the solar nebula theory the most accepted theory?
Space and AstronomyThe nebular hypothesis is the most widely accepted model in the field of cosmogony to explain the formation and evolution of the Solar System (as well as other planetary systems). It suggests the Solar System is formed from gas and dust orbiting the Sun. What is the most accepted theory about the solar system? the

How do you describe the end behavior of a polynomial?
Space and AstronomyThe end behavior of a polynomial function is the behavior of the graph of f(x) as x approaches positive infinity or negative infinity. The degree and the leading coefficient of a polynomial function determine the end behavior of the graph. How do you find the end behavior of a polynomial? To determine its end behavior,

How do you solve for r in circumference?
Space and AstronomyHow do you find the R in a circle? How to Find the Radius of a Circle? When the diameter is known, the formula is Radius = Diameter/ 2. When the circumference is known, the formula is Radius = Circumference/2π. When the area is known, the formula for the radius is Radius = ⎷(Area of
