The Moon is about 30 Earth diameters distant (i. e. you could fit about 30 Earths in a line from the Earth to the Moon). Let's say you use a 1-foot basketball to represent the Earth and a 3-inch orange to represent the Moon. About how far must they be placed apart to represent an accurate scale of the Earth and Moon?

seeing the graph would

luster is not a good characteristic to use by itself because luster is the property of minerals that indicates how much the surface of a mineral reflects light. the luster of a mineral is affected by the brilliance of the light used to observe the mineral surface.

see the picture for the vector

the magnitude of the vector by pythagorean theorem

r = √( (-10)^2 + (3)^2 ) = √109

magnitude = √109 units

the direction angle between vector and x-axis is

tan^(-1)(3/10) = 16.699

so the direction is approximately 16.7 degrees north of west
