Many sources of energy such as nuclear, coal, and oil use a fuel source to turn water into steam. The steam is then used to turn a turbine and generate electricity. Why are these sources not very efficient?

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.

force tends to be low and long diustance masses are high
