How did the solar system formed nebular theory?
Space and AstronomyApproximately 4.6 billion years ago, the solar system was a cloud of dust and gas known as a solar nebula. Gravity collapsed the material in on itself as it began to spin, forming the sun in the center of the nebula. With the rise of the sun, the remaining material began to clump together. How
Are math formulas given on the act?
Space and AstronomyThe two biggest challenges of ACT Math are the time crunch—the math test has 60 questions in 60 minutes! —and the fact that the test doesn’t provide you with any formulas. All the formulas and math knowledge for the ACT comes from what you’ve learned and memorized. Do you get a math formula sheet on
What are the undefined terms?
Space and AstronomyUndefined terms are those terms that don’t require a formal definition. The four terms are point, line, plane, and set. A point is quite simply, a dot. Points are labeled with one capital letter. What are examples of undefined terms? In geometry, point, line, and plane are considered undefined terms because they are only explained
How many types of solid shapes are there?
Space and AstronomyAnswer: The major types of solid shapes are: cubes, cuboids, prisms, pyramids, platonic solids, torus, cone, cylinder, and sphere. Question 4: Explain what is a sphere? What is a solid shape? A 3-D shape, or solid, is an object with three dimensions: length, width, and height. Solids have surface areas (the outside of the object)
What is the complement of a variable?
Space and AstronomyThe complement is the inverse of a variable and is indicated by a bar over variable (overbar). For example, the complement of the variable A is A. If A = 1, then A = 0. If A = 0, then A = 1. How do you find the complement of a variable? Note− The complement
What are the characteristics of the universe during the Big Bang?
Space and AstronomyThe Big Bang marked the origin of the universe, the beginning of its expansion from a singularity (or something close to a singularity), a single point that was infinitely small, infinitely hot, and infinitely dense. What are the 4 evidence of the Big Bang? The growth and evolution of galaxies and large-scale structure in the
What are the GREY areas on the moon?
Space and AstronomyThose spots are called maria, from the Latin word for sea, because early astronomers mistakenly thought they were lunar seas (they’re actually volcanic plains). The smooth and dark maria cover 17 percent of the surface of the moon. Almost all of them are visible from Earth. What are the gray spots on the Moon? Eyeballing
How do you find the complex roots of a complex number?
Space and AstronomyWe can find the roots of complex numbers easily by taking the root of the modulus and dividing the complex numbers’ argument by the given root. This means that we can easily find the roots of different complex numbers and equations with complex roots when the complex numbers are in polar form. How do you
Is a Lightyear a measure of time?
Space and AstronomyA light-year is a measurement of distance and not time (as the name might imply). A light-year is the distance a beam of light travels in a single Earth year, which equates to approximately 6 trillion miles (9.7 trillion kilometers). Is Lightyear a distance or time? Light-year is the distance light travels in one year.
Which figures are quadrilaterals with at least one pair of parallel sides?
Space and AstronomySolution A trapezoid is a quadrilateral with one pair of opposite sides parallel. … Sometimes people define trapezoids to have at least one pair of opposite sides parallel, and sometimes say there is one and only one pair of opposite sides parallel. What Quadrilaterals have at least one pair of parallel sides? Trapezoid — a
