What is the speed of a wave that has a wave length of 2m and a frequency of 6hz?

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.

the electric field is a “force field” around a charged object that illustrates the direction the electric force would push an imaginary
