question 7
what does your answer to the previous
question tell you about what is
happening to earth’s speed?
hint: think about what happens to the
length of the velocity vector.
answer:

Explanation:

The velocity vector's length represents speed. If the length (magnitude) of the velocity vector changes, the speed changes. If it increases, Earth's speed is increasing; if it decreases, Earth's speed is decreasing.

Answer:

If the length of the velocity vector (which represents speed) is increasing, Earth's speed is increasing. If the length is decreasing, Earth's speed is decreasing.
