Respuesta :

iven:

he aangles of the stars;

Star A: p_A=0.67 arcsec

Star B: p_B=1.2 arcsec

Star C: p_C=0.35 arcsec

To find:xoplanation:

Order of the stars according to their distance.

he distacnce of a star in parsec is calculated using the formula,

[tex]D=\frac{1}{p}[/tex]

Where p is the angles made by the stars in arcseconds.

On substituting the known values:

Star A,

[tex]\begin{gathered} D_A=\frac{1}{p_A} \\ =\frac{1}{0.67} \\ =1.5\text{ parsec} \end{gathered}[/tex]

Star B,

[tex]\begin{gathered} D_B=\frac{1}{p_B} \\ =\frac{1}{1.2} \\ =0.83\text{ parsec} \end{gathered}[/tex]

Star C,

[tex]\begin{gathered} D_C=\frac{1}{p_C} \\ =\frac{1}{0.35} \\ =2.9\text{ parsec} \end{gathered}[/tex]

inal answer:

Thus the closest star is star B and the farthest star is star C.

Thus the correct answer is option B.
