Vedclass · Answer

(A) The angular diameter $\alpha$ is given as $1920^{\prime \prime}$.First,convert the angular diameter from arcseconds to radians:$\alpha = 1920 	imes 4.85 	imes 10^{-6} \ rad = 9.312 	imes 10^{-3} \ rad$.The diameter $d$ of the Sun is related to the angular diameter $\alpha$ and the distance $D$ by the formula $d = \alpha D$.Substituting the values:$d = (9.312 	imes 10^{-3} \ rad) 	imes (1.496 	imes 10^{11} \ m)$.$d \approx 1.393 	imes 10^{9} \ m$.

The Sun's angular diameter is measured to be $1920^{\prime \prime}$. The distance $D$ of the Sun from the Earth is $1.496 \times 10^{11} \ m$. What is the diameter of the Sun?
