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) The center of our galaxy because the Sun moves around the galactic center. For the latter, the period is 2.5 x 108 y and the radius is 2.2 x 1020 m. Calculate these three accelerations as multiples of g = 9.8 m/s2.
