What is the solar nebula?
Space and Astronomysolar nebula, gaseous cloud from which, in the so-called nebular hypothesis of the origin of the solar system, the Sun and planets formed by condensation. What is a solar nebula in simple words? Solar-nebula definition A large cloud of gas and dust from which the sun, planets, and other solar system bodies formed. What was
What is the complement Theorem?
Space and AstronomyThe complementary angle theorem states, “If two angles are complementary to the same angle, then they are congruent to each other“. How do you prove complement Theorem? If two angles are complementary to the same angle (or to congruent angles), then they are congruent. If ∠4 and ∠5 are complementary and ∠6 and ∠5 are
What do scientists know about Saturn?
Space and AstronomyAdorned with thousands of beautiful ringlets, Saturn is unique among the planets. It is not the only planet to have rings – made of chunks of ice and rock – but none are as spectacular or as complicated as Saturn’s. Like fellow gas giant Jupiter, Saturn is a massive ball made mostly of hydrogen and
What is an Arccosine?
Space and AstronomyThe arccosine is the inverse function of the cosine function. This means that they are opposite functions, and one will cancel out the other. The arccosine is mainly used to determine the measure of an angle when two sides of a right triangle are known. What is the meaning of arccosine? arccosine in British English
What is conics in precalculus?
Space and AstronomyWhat is conic section in calculus? The conic sections are the shapes that can be created when a plane intersects a double cone like the one below. In other words, the conic sections are the cross sections of a double cone. There are four primary conic sections – the circle, the parabola, the ellipse, and
What is a cross section of a 3d figure?
Space and AstronomyA cross-section is a plane section that is a section of a three-dimensional object that is parallel to one of its planes of symmetry or perpendicular to one of its lines of symmetry. Describe shapes formed by cross-sections (square, rectangle, triangle, etc). What is the cross section of a 3D object? A cross section is
How is Star magnitude measured?
Space and AstronomyOne magnitude is defined as a ratio of brightness of 2.512 times; e.g., a star of magnitude 5.0 is 2.512 times as bright as one of magnitude 6.0. Thus, a difference of five magnitudes corresponds to a brightness ratio of 100 to 1. What is a star magnitude scale? The magnitude scale is a logarithmic
Is the square root of a negative number imaginary?
Space and AstronomyThe square root of a negative number does not exist among the set of Real Numbers. really meant. In an effort to address this problem, mathematicians “created” a new number, i, which was referred to as an “imaginary number”, since it was not in the set of “Real Numbers”. Is the square root of a
What are concentric triangles?
Space and AstronomyIn geometry, two or more objects are said to be concentric, coaxal, or coaxial when they share the same center or axis. Circles, regular polygons and regular polyhedra, and spheres may be concentric to one another (sharing the same center point), as may cylinders (sharing the same central axis). What is a concentric in geometry?
What comes first in a glide reflection?
Space and AstronomyA glide reflection is a composition of transformations.In a glide reflection, a translation is first performed on the figure, then it is reflected over a line. Therefore, the only required information is the translation rule and a line to reflect over. How do you know if its a glide reflection? A glide reflection is a
