Can the velocity of an object change when it’s acceleration is constant? if so give example. if not explain

Yes the velocity changes.

Explanation:

Acceleration is defined as the rate of change of velocity.Acceleration can be uniform and non uniform. In uniform acceleration the velocity changes at a uniform rate and in non uniform acceleration it changes at a non uniform rate.

In the given case it is uniform acceleration. So the velocity will change at a uniform rate .

Hence at every instant velocity will keep changing.

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.

c)as speed changes, wavelength and frequency change.

everything changes!
