An equipment catalog boasts that a pressure transducer system comes in 31=2-digit (e. g., 19: 99) or 41=2-digit (e. g., 19: 999) displays. the 41=2-digit model costs substantially more. both units are otherwise identical. the specifications list the uncertainties for three elemental errors: problems 211linearity error: 0.15% fso hysteresis error: 0.20% fso sensitivity error: 0.25% fso for a full-scale output (fso) of 20 kpa, select a readout based on appropriate uncertainty calculations. explain.

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.

i don't understand. explain it clearly

the order for strong to weak forces such as

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

the fundamental forces are those forces that act between to objects or element to make interactions. there are four types of fundamental forces such as strong and weak nuclear forces (due to protons and electrons), electromagnetic force (due to the motion of electrons) and gravitational force (due to orbital movement of the planet). if these forces are arranged on the basis of their maximum strength then the order is

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force
