What is the force of a 500kg car that is accelerating at 20m /sex2?

10000N

Explanation:formuler for calculating force is given by F=Ma

M(mass)=500kg

a(acceleration)=20m/s^2

Therefore by substitution we have F=500*20

F=10000N

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.

the answer is b i think
