Which type of supernova can be used as a standard candle?
Space and Astronomytype 1a supernovaetype 1a supernovae being called “cosmic mile markers” and “standard candles.” What type of supernova is a standard candle? type Ia supernovae Since type Ia supernovae have a known brightness they can be used as standard candles to determine the distance to a galaxy once the stretch-factor is accounted for. Is a Type

How does a convex mirror reflect light?
Space and AstronomyConvex mirrors When parallel light rays hit a convex mirror they reflect outwards and travel directly away from an imaginary focal point (F). Each individual ray is still reflecting at the same angle as it hits that small part of the surface. Parallel rays of light strike the mirror and are reflected outwards. How do

How much would it cost for the US to convert to the metric system?
Space and Astronomy$370 millionover $370 million. Will the US ever switch to metric system? The United States has official legislation for metrication; however, conversion was not mandatory and many industries chose not to convert, and unlike other countries, there is no governmental or major social desire to implement further metrication. What would happen if the US switched

How does an armillary sundial work?
Space and AstronomyIn use since Grecian times, armillaries are composed of complex, interlocking spheres supporting an arrow-shaped gnomon. As the sun travels across the sky, the gnomon casts a shadow onto a surface that indicates the hour. Armillary sundials are usually made of cast brass, bronze or aluminum. How do you set up an armillary sundial? Locate

What is the difference between Calla and arum lily?
Space and AstronomyThere are a few ways to distinguish the two, however. Arum lilies belong to the Zantedeschia genus (of which Zantedeschia aethiopica, a white variety, is the most well known), and they are larger and have a more open, flat shape. Calla lilies, a part of the Calla genus, tend to be smaller and more tightly-wound.
