If a vector of magnitude 3 is added to a vector of magnitude 4 what can the magnitude of the resultant be?
7
What is the angle between two vectors of equal magnitude whose resultant is equal to the magnitude of either vector?
69 degrees
Why can vectors be used to represent forces?
A vector is a quantity with magnitude and direction. Since force has magnitude and direction, it is a vector
When magnitude of vector a plus b is equal to the magnitude of vector a minus b then what is the angle between two vectors a and b?
2pi/3 radian or equivalent 120 degree
What can you say about two vectors if vector A vector B 0?
Depends on the situation. Vector A x Vector B= 0 when the sine of the angle between them is 0 Vector A . Vector B= 0 when the cosine of the angle between them is 0 Vector A + Vector B= 0 when Vectors A and B have equal magnitude but opposite direction.
Can the magnitude of the difference between two vectors ever be greater than the magnitude of either vector?
No.
Vector component greater than the vectors magnitude?
can a vector have a component greater than the vector magnitude
What two vectors does a vector have?
It has both velocity and direction. A vector has direction and magnitude.
What is it when two vectors' dot product is one?
That fact alone doesn't tell you much about the original two vectors. It only says that (magnitude of vector-#1) times (magnitude of vector-#2) times (cosine of the angle between them) = 1. You still don't know the magnitude of either vector, or the angle between them.
If a vector of magnitude 3 is added to a vector of magnitude 4 what can the magnitude of the resultant be?

Is the sum of two vectors of equal magnitude equal to the magnitude of either vectors AND their difference root 3 times the magnitude of each vector?
iff the angle between them is 120 degrees
What is the angle between two vectors of equal magnitude whose resultant is equal to the magnitude of either vector?
69 degrees
What is the difference between a scalar quantity and a vector?
Scalars are quantities that have magnitude only; they are independent of direction. Vectors have both magnitude and direction. vectors need bold letters to show them.
Can a vector have a component greater than vectors magnitude?
No.

What can you say about two vectors if vector A vector B 0?
Depends on the situation. Vector A x Vector B= 0 when the sine of the angle between them is 0 Vector A . Vector B= 0 when the cosine of the angle between them is 0 Vector A + Vector B= 0 when Vectors A and B have equal magnitude but opposite direction.
