What’s a good magnification for telescope?
Space and AstronomyFor most purposes, a telescope’s maximum useful magnification is 50 times its aperture in inches (or twice its aperture in millimeters) . So you’d need a 12-inch-wide scope to get a decent image at 600×. And even then, you’d need to wait for a night when the observing conditions are perfect. What magnification telescope do
What is in a supergiant star?
Space and AstronomySupergiant stars form out of massive main-sequence stars that have run out of hydrogen in their cores. This causes them to expand greatly, similarly to low-mass stars, however, they begin to fuse helium in their core not long after exhausting their hydrogen supplies. What is inside the supergiant star? Supergiants develop when massive main-sequence stars
What makes the Hubble Space Telescope unique?
Space and AstronomyIt is a very special telescope which orbits far above the Earth. Hubble allows us to see objects more clearly because it is above the clouds in Earth’s atmosphere. These clouds block the view of the Earth-based telescopes which scientists have used for many years. Why is the Hubble space telescope so unique? Hubble’s incredible

How long does a blue supergiant last?
Space and Astronomyaround 10 million yearsaround 10 million years, which sounds like a long time … How long do blue Giants last? 10 million years Their lifetimes are a mere 10 million years (the Sun’s is about 10 billion) – by the time the Sun has lived and died, a thousand blue supergiants could have been born,
How do you find the domain of X?
Space and AstronomyFunctions assign outputs to inputs. The domain of a function is the set of all possible inputs for the function. For example, the domain of f(x)=x² is all real numbers, and the domain of g(x)=1/x is all real numbers except for x=0. We can also define special functions whose domains are more limited. What is
What is SSA congruence rule?
Space and AstronomyWhat is the SSA Congruence Rule? The SSA congruence rule states that if two sides and an angle not included between them are respectively equal to two sides and an angle of the other then the two triangles are equal. Why is SSA not congruent? Knowing only side-side-angle (SSA) does not work because the unknown
What is the absolute extrema in calculus?
Space and AstronomyAbsolute extrema are the largest and smallest the function will ever be and these four points represent the only places in the interval where the absolute extrema can occur. How do you find the absolute extrema? To find the absolute extrema of a continuous function on a closed interval [a,b]: Find all critical numbers c
What are shapes defined by?
Space and AstronomyIn geometry, a shape can be defined as the form of an object or its outline, outer boundary or outer surface. What makes a shape shape? At its most basic, a shape is created when a line is enclosed: a line forms the boundary, and the shape is the form circumscribed by that boundary. Line
What is an undefined expression?
Space and AstronomyWhat does it mean when expression is undefined? An expression that is undefined means that the denominator of the expression is equal to zero. Therefore, the expression cannot be determined at that value. What is an example of an undefined expression? A rational expression is undefined when the denominator is equal to zero. To find
