What is Boolean logic used for?
Space and AstronomyWhat is Boolean logic? Programs use simple comparisons to help make decisions. Boolean logic is a form of algebra where all values are either True or False. These values of true and false are used to test the conditions that selection and iteration are based around. What can Boolean be used for? Boolean Operators are
What kind of mirror is used in vehicles?
Space and AstronomyConvex mirrorConvex mirror: different uses One of the most common uses for the convex mirror is the passenger-side mirror on your car. These convex mirrors are used for cars because they give an upright image and provide a wider field of view as they are curved outwards. What type of mirror is used in vehicles?
Why is the circumference of 2 Pi r?
Space and AstronomyIt sounds like you are aware of this, but just to clarify: the formulae 2πr and πd for the circumference of the circle are equivalent because the diameter is twice the radius. The former statement is often more useful simply because the radius of a circle is a property that we often refer to. Why
Is every group of order 4 cyclic?
Space and AstronomyWe will now show that any group of order 4 is either cyclic (hence isomorphic to Z/4Z) or isomorphic to the Klein-four. Is group of order 4 always cyclic? The order of an element of a group must divide the order of the group. So a group of order 4 can only have elements of
Where are most comets in our solar system located?
Space and AstronomyThere are likely billions of comets orbiting our Sun in the Kuiper Belt and even more distant Oort Cloud. Where are most comets found in the solar system? The Oort Cloud It is thought that most comets originate in a vast cloud of ice and dust that surrounds the solar system. The Oort Cloud, as
Can you see stars during an eclipse?
Space and AstronomyIn addition to bringing the sun’s corona into view, totality makes the surrounding sky so dark that viewers can see stars and planets during the day. Are stars visible during a lunar eclipse? Its young stars — just 600 million years old (the Sun is 4.5 billion years old, remember!) — look stunning in a

How do you write a linear combination?
Space and AstronomyIn mathematics, a linear combination is an expression constructed from a set of terms by multiplying each term by a constant and adding the results (e.g. a linear combination of x and y would be any expression of the form ax + by, where a and b are constants). How do you write an equation
What was the purpose of WMAP?
Space and AstronomyThe main goal of WMAP was to create extremely precise full-sky maps of the cosmic microwave background, improving upon the maps created by COBE. Since the differences in temperature are only on the order of 0.0002 degrees Celsius, precision was essential to obtaining useful information. What was the significance of the WMAP image What did
What is the length of a rectangle calculator?
Space and AstronomyHow do I find the length of a rectangle? How do I calculate the length of a rectangle? If you have the area A and width w , its length w is determined as h = A/w . If you have the perimeter P and width w , its length can be found with h
