Frequency of 2 hertz and wavelength of 5 meters. Calculate speed.

Speed = 10 m

Explanation:

Given

wavelength = 5 m

frequency = 2 Hz = 2

Speed = ?

We know that for all waves, the relationship between wavelength λ, frequency f and speed v is same and given by the equation:

                                v = fλ

Hence, Speed = 2 x 5 m

                         = 10 m

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.
