Earth makes 1 complete revolution around the Sun after approximately 365 days. The angular speed in rev/min may be determined by using dimensional analysis and conversion factors.
(1 rev/365 days) x (1 day/ 24 hours) x (1 hour/ 60 mins) = 1.90 x 10^-6 rev/min
Therefore, Earth's angular speed is approximately 1.90x10^-6 rev/min.
