A bus moving with acceleration 2m/s^2. What does it mean

a bus moving with acceleration of 2 meter per second square

It means that it's velocity is 2m/s per s

Means it travels 2m in 1st second and 4m in 2nd sec

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.

where is the circuit diagram ?
