Use the Pythagoras theorem to solve for R (resultant).
R = 2.44 km North East
-- Earth's average distance from the sun is about 93 million miles.
-- Mars' average distance around the sun is about 142 million miles.
-- So, as both planets travel in their orbits around the sun, the distance
between them changes, between (142 - 93) = about 49 million miles
and (142 + 93) = about 235 million miles.
Kinetic energy is movement, thus movement would be a characteristic that allows an object to have kinetic energy
It is true that polarized light consists of waves that vibrate in one direction only.
