Question

What is the properties of matrices and how many ???​

Answer 1

Answer:

Step-by-step explanation:

We know that, R = V^2 /P

Hence resistance of 1st bulb = (250)^2 / 200 = 625/2

resistance of 2nd bulb = (250)^2 / 100 = 625

Total resistance of the circuit when the bulbs are connceted in series = 625/2 + 625 = 1875/2 ohm

Therefore, total power consumed in the circuit , P = (250)^2 / (1875/2) = 67 watt

Answer 2

Answer:

Matrices rarely commute even if AB and BA are both defined. There often is no multiplicative inverse of a matrix, even if the matrix is a square matrix. There are a few properties of multiplication of real numbers that generalize to matrices.
