A car speeds up from 12 m per second to 20 m per second in 6.4 seconds. If its mass is 1200 kg what force must its engine provide?

this one:

as we gain mass the force of gravity on us increases.

pls mark me as the ! : d

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.

because if the tool that you are using is not balanced it there would be false mass.
