Asap! a certain wave has a frequency of 200 hz and a wavelength of 2 meters. calculate the wave speed. show work! question 13 options:

400 m/s

Explanation:

From the question;

We are required to calculate the speed of the wave;

Speed of the wave = 200 Hz × 2 m

                               = 400 m/s

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.

like poles repel so keep pushing north to north and repels funny to see this
