Earth radius in si units
WebFeb 4, 2024 · The Schwarzschild radius of the sun is R = 2 G M / c 2, which can be written simply as R = 2 M in units where c = G = 1. Either way, it comes out to be R ≈ 3 km. On … WebAngular Speed of Earth Our Earth takes about 365.25 days to finish one revolution around the Sun. Converting days into seconds, we get T = 365.25 x 24 x 60 x 60 = 31557600 seconds We know that angular speed = 2π/T, hence ω = 1.99 x 10 -7 radians /seconds. The angular speed of Earth is 1.99 x 10 -7 radians /seconds. Angular Speed Examples

WebIn simple words, angular velocity is the time rate at which an object rotates or revolves about an axis. Angular velocity is represented by the Greek letter omega (ω, sometimes Ω). It is measured in angle per unit time; hence, the SI unit of angular velocity is radians per second. The dimensional formula of angular velocity is [M 0 L 0 T -1 ].
