What is the slope of a line parallel to Y?
Space and AstronomyThe slope of the equation of line parallel to y axis is undefined. The line parallel to y axis is at an angle of 90º to the x – axis and the slope of this line is tan90º, which is undefined. What is the slope parallel to Y? no slope A line parallel to the
What causes change in daylight?
Space and AstronomyThe change between day and night is caused by the rotation of the Earth on its axis. … The changing lengths of days and nights depends on where you are on Earth and the time of year. Also, daylight hours are affected by the tilt of the Earth’s axis and its path around the sun.
What is a Lambert map projection?
Space and AstronomyLambert conformal projection, conic projection for making maps and charts in which a cone is, in effect, placed over the Earth with its apex aligned with one of the geographic poles. What does a Lambert map projection show? Description. The Lambert azimuthal equal-area projection maintains land features at their true relative sizes while simultaneously maintaining
Can a square have a radius?
Space and AstronomyA square doesn’t have a radius. What is squared radius? The formula for area equals pi times the radius squared, R stands for the radius measurement of the circle. How do you find the radius of a square? To find the area using the radius, or the length from the center of the circle to
What is a perpendicular line in geometry?
Space and AstronomyPerpendicular lines are lines that intersect at a right (90 degrees) angle. What is an example of a perpendicular line? Lines that intersect each other forming a right angle are called perpendicular lines. Example: the steps of a straight ladder; the opposite sides of a rectangle. How do you know if a line is perpendicular?
What keeps a satellite up in its orbit around the Earth?
Space and AstronomyA satellite maintains its orbit by balancing two factors: its velocity (the speed it takes to travel in a straight line) and the gravitational pull that Earth has on it. What are the force that keep a satellite in its orbit? That is to say, a satellite is an object upon which the only force
What is a ray line line segment and angle?
Space and AstronomyA line is a straight path that continues forever in both directions. A ray is part of a line. A ray has one endpoint and continues forever in one direction. A line segment is part of a line. It is the part of a line between two endpoints. What is ray and line? A line
What is the difference between an open path and a closed path read more >>?
Space and AstronomyAn open path has endpoints. It starts in one place and ends in another place — clearly a line segment, and not a polygon. A closed path has no starting point and no endpoint. What is an open path in InDesign? In page layout programs, such as Adobe InDesign, and graphics programs, such as Adobe
How do you find the Directrix of an ellipse?
Space and AstronomyFor the ellipse x2a2+y2b2=1 x 2 a 2 + y 2 b 2 = 1 , the equations of the two directrix of ellipse is x = +a/e, and x = -a/e. The directrix of the ellipse is equidistant from the center of the ellipse. The two directrices of the ellipse are parallel to each
Can a central angle be obtuse?
Space and AstronomyWhat is a obtuse central angle? An obtuse angle is a type of angle that is always larger than 90° but less than 180°. In other words, it lies between 90° and 180°. Can a central angle be greater than 180? There are two types of central angles. A convex central angle, which is a
