Problem

The Sun has an equatorial radius of

6.96 \times 10^5 \text{ km}

. It rotates with a period, at the equator, of 24.47 days. The Earth's equatorial radius is

6.37 \times 10^3 \text{ km}

. Calculate the ratio of the Sun's a. a angular velocity at the equator to the Earth's angular velocity at the equator,

\frac{\omega_S}{\omega_E}

. b. b linear speed at its equator to the Earth's linear speed at its equator,

\frac{v_S}{v_E}
