Which type of galaxy is the youngest?
Space and AstronomyGN-z11 is the youngest and most distant galaxy scientists have observed. Is irregular The youngest galaxy? Astronomers have measured the age of irregular galaxies and their ages are older than spirals, but younger than ellipticals. They are like teenage galaxies. Which of the galaxies looks youngest to us? The galaxy is ancient, but from the
What is the meaning of s in Heron’s formula?
Space and Astronomythe semi-perimeter of the trianglethe semi-perimeter of the triangle; that is, Heron’s formula can also be written as. How do you solve for S in Heron’s formula? Video quote: And there we just take a plus B plus C and divide it by two we'll get a value for s. What is the mean of
What causes a Super Blue Blood Moon?
Space and AstronomyA rare celestial event will grace the skies during the coming week when ablue moon and lunar eclipse combine with the moon being at its closest point to Earth, resulting in what is being called a “super blue blood moon”. What causes a Super Blood moon? The moon is fully in Earth’s shadow. At the
Was there a blood moon in 2014?
Space and AstronomyThe first Blood Moon eclipse in the series of four happened on the night of April 14-15, 2014. The second one took place October 7-8, 2014, and the third one (the shortest total lunar eclipse of the 21st century) was April 4, 2015. What year did we have a blood moon? When is the next
How do you prove a quadrilateral is a parallelogram?
Space and AstronomyTo prove a quadrilateral is a parallelogram, you must use one of these five ways. Prove that both pairs of opposite sides are parallel. Prove that both pairs of opposite sides are congruent. Prove that one pair of opposite sides is both congruent and parallel. Prove that the diagonals bisect each other. What are the
What is included in pre algebra?
Space and AstronomyPre-algebra is a course designed to prepare students for a standard high school algebraic course. Students are introduced to integers, fractions, square roots, step equations, linear equations and decimals and are taught how to solve basic equations using variables. Does pre algebra include geometry? Pre-algebra may include subjects from geometry, especially to further the understanding
How do you place a sundial?
Space and AstronomyWhich way do you face a sundial? Sundials need to point in the direction of True North, and the style (either a sharp straight edge or thin rod, often located at the edge or tip of the gnomon) must be aligned with the Earth’s rotational axis. Can you put a sundial anywhere? One can install
What happens to a star as it ages?
Space and AstronomyWhy do stars expand as they age? As the core heats up, it holds off gravity for a while longer. This allows the star to start fusing Helium into Carbon and Oxygen. This build up of heat expands the outer layers of the star and they expand outward, causing a star like our sun to
How do you construct a perpendicular line through a given point not on the line?
Space and AstronomyHow do you construct a perpendicular line through a point off the line? Video quote: That line segment a B is perpendicular to line PE and remember this is the symbol for perpendicular. So we have line segment a B is perpendicular to line PE. How do you construct a line parallel to the given
How is a rectangle different from a rhombus?
Space and AstronomyA rhombus has four equal sides, whereas, in a rectangle, the opposite sides are equal. The diagonals of a rhombus bisect each other at 90°, whereas the diagonals of a rectangle bisect each other at different angles. In a rhombus, the opposite angles are equal, whereas, in a rectangle, all angles measure 90°. What is
