Displacement vector points due east and has a magnitude of 3.35 km. displacement vector points due north and has a magnitude of 9.31 km. displacement vector points due west and has a magnitude of 6.66 km. displacement vector points due south and has a magnitude of 3.65 km. find (a) the magnitude of the resultant vector + + + , and (b) its direction as a positive angle relative to due west.

(a) 6.56 km

(b) north of west

Explanation:

Given:

Let the resultant displacement vector be .

As the resultant is the vector sum of all the vectors.

answer: d. a cme increases the amount of energy in the solar wind

explanation:

coronal mass ejections, also called cmes, are large clouds of plasma and magnetic field that erupt from the sun. only when the cloud is aimed at earth will the cme hit earth and therefore cause impacts. high-speed solar wind streams come from areas on the sun known as coronal holes.

report!

explanation:

physics means: "the branch of science concerned with the nature and properties of matter and energy. the subject matter of physics, distinguished from that of chemistry and biology, includes mechanics, heat, light and other radiation, sound, electricity, magnetism, and the structure of atoms."
