Question #7b8da

Answer 1

This is simply the measure of how great that vector is.

Explanation:

Recall: A vector is a quantity that can be described by its magnitude and its direction.

Example
A car is travelling on a level road with a velocity of `5km"/"h` in a direction West.

If we wanted to describe the car's velocity, its magnitude(how big is the velocity? How fast is the car moving) is `5km"/"h`
whereas, its direction is West.

Another Example would be:
A man pushing a suitcase up a plane with a force of `2N`.

The magnitude of the force is simply `2N`.
In which direction is he pushing? Along the plane.
