How do you find the absolute magnitude of the sun?
Space & NavigationThe Sun has absolute magnitude MV = +4.83. How do you solve for the absolute magnitude of the Sun? Determine its absolute magnitude. It is given that the distance between the sun and the earth is 1.5 x 10^11m. The absolute magnitude M of a star is the magnitude which the star would have if

What is line and plane?
Space & NavigationUnlike a plane, a line in three dimensions does have an obvious direction, namely, the direction of any vector parallel to it. In fact a line can be defined and uniquely identified by providing one point on the line and a vector parallel to the line (in one of two possible directions). What is a

How do you calculate LxWxH?
Space & NavigationMultiply the length (L) times the width (W) times the height (H). The formula looks like this: LxWxH For this example, to calculate the volume of the object the formula would be 10 x 10 x 10 = 1,000 cubic inches. What is the formula for LxWxH? Use multiplication (V = l x w x

How do you prove a trapezoid is a trapezoid?
Space & NavigationHow do you prove that ABCD is a trapezoid? Use the slope formula to find the slope of the sides of the quadrilateral. The slopes of exactly one pair of opposite sides are equal, so they are parallel. Therefore, quadrilateral ABCD is a trapezoid. How do you know if something is a trapezoid? A trapezoid,

What is a star’s temperature?
Space & NavigationThe surface temperatures of A-type stars range from 7,400 K to about 10,000 K; lines of hydrogen are prominent, and these stars are white. F-type stars are yellow-white, reach 6,000–7,400 K, and display many spectral lines caused by metals. Are stars Hot or cold? Red stars are the coolest. Yellow stars are hotter than red
