Using absolute magnitudes for the sun of mb = 5.48, mv = 4.83, and mr = 4.42, calculate the fluxes fλ (in units of erg cm−2 s −1 ˚a−1 ) and fν (in units of jy) received at earth from the sun when observing with the b, v , and r filters. ignore any absorption by the earth’s atmosphere.
(c) the st magnitude system is designed so that, for any filter, apparent magnitude zero corresponds to fλ = 3.63 × 10−9 erg cm−2 s −1 ˚a−1 . determine the apparent and absolute b, v , and r magnitudes of the sun in the st system.
(d) the ab magnitude system is designed so that, for any filter, apparent magnitude zero corresponds to fν = 3.63 × 10−20 erg cm−2 s −1 hz−1 = 3630 jy. determine the apparent and absolute b, v , and r magnitudes of the sun in the ab system.

Will give brainliest! which statement best describes the similarities between fundamental forces? electromagnetic and strong nuclear forces influence the interaction between charged particles within an atom. gravitational and magnetic forces are both types of charges that occur in nature. nuclear and magnetic forces are both related to mass and weight. strong nuclear force is most like electrical force because they are both related to distance.
