### What is the example of head to tail rule?

In addition of vector when vector A whose head is joined to the tail of the vector B and then the tail of the vector A is linked with the tail of the resultant vector and the head of the vector B is joined with the head of the resultant vector..... it means the addition of vectors are also defined the head to tail rule..

yes

### What is the opposite to vector addition?

the opposite to vector addition is vector subtraction.

### What is the reverse process of vectors addition?

reverse process of vector addition is vector resolution.

### Why is Vector resolution the opposite of vector addition?

Vector addition derives a new vector from two or more vectors, and vector resolution is breaking a vector down into its two or more components.

Yes.

### Who coined the phrase A vector is defined as that which has magnitude and direction?

The rule for vector addition is so intuitive that it was certainly well known by Heron of Alexandria (First Century AD). The origin of the phrase used in the question probably predates that.

### Is it possible for vector A plus vector B to equal vector A - vector B?

It's impossible as the addition of two vectors is commutative i.e. A+B = B+A.For subtraction of two vectors, you have to subtract a vector B from vector A.The subtraction of the vector B from A is equivalent to the addition of (-B) with A, i.e. A-B = A+(-B).
