An object lying on Earth$$s equator is accelerated $($a$)$ toward the center of Earth because Earth rotates, $($b$)$ toward the Sun because Earth revolves around the Sun in an almost circular orbit, and $($c$)$ toward the center of our galaxy because the Sun moves around the galactic center. For the latter, the period is $2\mathrm{.}5<10$ y and the radius is $2\mathrm{.}2<107$ m$.$ Calculate these three accelerations as multiples of g $=9\mathrm{.}8$ m$/$s$.$
