Beams of high-speed protons can be produced in "guns" using electric fields to accelerate the protons. (a) what acceleration would a proton experience if the gun's electric field were 2.69 × 104 n/c? (b) what speed would the proton attain if the field accelerated the proton through a distance of 1.24 cm?

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.

hèllo, sorry i really need some more points so if you need this qustion answered than retype it
