a) Using s = rθ, calculate the arc length (in meters) subtended by the sun when it moves an angular distance of 2 x10-6 °. The distance between the Earth and Sun is called an AU (astronomical unit). 1 AU = 1.5 x1011 m. (Don’t forget to convert to radians). As you can see from the above calculation, a small change in angle can correspond to a large distance. In astronomy angles are typically measured in arcminutes or arcseconds 1...
