How do rays reflect against a curved mirror?
Space and AstronomyOnce these incident rays strike the mirror, reflect them according to the two rules of reflection for concave mirrors. The ray that passes through the focal point on the way to the mirror will reflect and travel parallel to the principal axis. How do curved mirrors reflect light? A concave mirror, or converging mirror, has
Why do sunspots always appear in pairs?
Space and AstronomyThe turbulent motions in the Sun’s interior fragment the loops in the solar magnetic field. Sunspots generally appear in opposite-polarity pairs or in opposite-polarity groups when the magnetic field is fractured. Why do sunspots occur in pairs quizlet? sunspots occur in pairs connected by a loop of magnetic field lines that arc high above Sun’s
Is my child ready for pre algebra?
Space and AstronomyIn what grade does a student typically start pre-algebra? Pre-algebra is typically taught in 6th or 7th grade. Of course, your child might be ready sooner or later. More important than grade level is your child’s ability to handle more complex math concepts. How do you know if your student is ready for algebra? starting
What is positive and negative space in graphic design?
Space and AstronomyPositive and negative space are terms referring to composition in art, graphic design, and photography. Positive space is the subject or areas of interest in artwork, and negative space is the space around the focal point. What is positive space in graphic design? Positive space refers to the subject or areas of interest in an
Why are galaxies moving away from each other?
Space and AstronomyGalaxies rotate around their centers with the sections of the galaxy that are farther out from the galaxy’s center rotating more slowly than the material closer to the center. Galaxies are also moving away from each other due to the expansion of the Universe brought on by the Big Bang. Why all galaxies appear to
What has parallel sides but is not a trapezoid?
Space and AstronomyAlso opposite angles are equal (angles “A” are the same, and angles “B” are the same). NOTE: Squares, Rectangles and Rhombuses are all Parallelograms!…The Trapezoid (UK: Trapezium) Trapezoid Trapezium In the US: a pair of parallel sides NO parallel sides In the UK: NO parallel sides a pair of parallel sides What shape has parallel
How do you find the area of a polygon with vertices?
Space and AstronomyHow do you find the Area of Polygons with Vertices? Step 1: Find the distance between all the points using the distance formula, D = √(x2−x1)2+(y2−y1)2 ( x 2 − x 1 ) 2 + ( y 2 − y 1 ) 2. Step 2: Once we know the dimensions of the polygons are known
What is the hottest planet in the universe?
Space and AstronomyVenusMean Temperatures on Each Planet Venus is the exception, as its proximity to the Sun, and its dense atmosphere make it our solar system’s hottest planet. What is the hottest planet in the entire universe? Venus is the hottest planet in the solar system. Although Venus is not the planet closest to the sun, its
What is radius of a circle in math?
Space and AstronomyRadius is defined as a line segment joining the center to the boundary of a circle or a sphere. The length of the radius remains the same from the center to any point on the circumference of the circle or sphere. It is half of the length of the diameter. How do we find the
What is a bar model in algebra?
Space and AstronomyIn math, a bar model can be defined as a pictorial representation of a number in the form of bars or boxes used to solve number problems. Bar models help us to attain an understanding of how a problem needs to be solved and calculated. How do you use a bar model in algebra? Video
