ya yes its there a matrix called zero matrix
A sparse matrix is a matrix in which most of the elements are zero.
a squar matrix A is called involutary matrix. if A^2=I
A zero matrix is a matrix in which all of the entries are zero.
yes, it is true that the transpose of the transpose of a matrix is the original matrix

By adding Dummy Destination. Also see Dummy Destination for more info.
Total supply must equal to total demand in the transportation problem,but each supply and demand value is 1 in the assignment problem.

Suppose, the Chittagong plant capacity is 1300 cars instead of 1500 cars. Since the total supply (1000+1300+1200=3500) happens not equal the total demand (2300+1400=3700). Thus the resulting transportation model is said to be unbalanced. This unbalanced situation means that it will not be possible to fill all the demand at the distribution centre. Because the demand exceeds the supply, a dummy source (plant) with a capacity of 200 cars (3700-3500) is added to balance the transportation model. The unit transportation costs from the dummy plant to the two destinations are zero because the plant does not exist. The following table shows that the balanced model under the new capacity restriction of the Chittagong plant. The dummy plant has a capacity of 200 cars.
forces can be unbalanced because they are at differant hights there fore they are not at equal hights so they are unbalanced.
this is unbalanced forces.
No. There is no such thing as a single force that is balanced or unbalanced, and a desk is not a force anyway.
The result of unbalanced forces is a net force that can accelerate a body.
