Derived Physical Quantities

When dimensions of a given physical quantity are given,the physical quantity is unique .

If vecL and vecL are two length vectors, what physical quantity does [vecL xx vecL] represent ?

Assertion: If the initial and final positions coincide, the displacement is a null vector. Reason: A physical quantity can not be called a vector, if its magnitude is zero.
