Explain the difference between mass and weight for objects on earth and on the mooon

Explanation:

The amount of matter contained inside a body is called its mass while the weight of a body is the gravitational force with which it is attracted towards the earth.

Weight, W = mg

m is the mass and g is acceleration due to gravity  

The mass of the object on the moon remains the same but the weight of the body is reduced to one sixth. This is because the moon's gravity is less than the earth's gravity.            

Hence, this is the main difference in the weight of the object on the earth and on the moon.                                    

i think it because equal matrices have equal dimensions, only square matrices can be symmetric. for all indices and . every square diagonal matrix is symmetric, since all off-diagonal elements are zero. in linear algebra, a real symmetric matrix represents a self-adjoint operator over a real inner product space.
