cross multiplication means that you multiply

Resistance of a conductor is inversely proportional to the area of the cross-section of the uniform wire. That means thinner the wire greater the resistance and thicker the wire lower the resistance. If A is the area of cross-section of the uniform wire, then By com..

Let A be a matrix of order mxn. Let B be a matrix of order nxp. Then the product of the matrices A and B is of order mxp. i.e., when we multiply two matrices the number of columns of the first matrix should be equal to the number of rows of the second matrix. Two matrices can be mul..
