How much tension must a rope withstand if used to accelerate a 960-kg car from rest horizontally along a frictionless surface to 1.20 m/s in 5 seconds?

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.

a lot of it means it can be "burned" for energy and sold at one price. if it is scarce, the price will go up
