Answer 1

Answer:

Question:-

The average distance of sun from earth is 1.496 x 10¹¹ m. Express it in light year (ly) and parsec .

Answer:-

Distance between Earth and sun= 1.496×10¹¹m

Speed of light= 3×10¹¹m/s

By using Formula:

${\boxed{ \red{ \bf{speed = \frac{distance}{time} }}}}$

$or \: 3 \times {10}^{11} m/s= \frac{1.496 \times {10}^{11} m }{time}$

$so, time = \frac{1.496 \times {10}^{11} m}{3 \times {10}^{8}m/s } = \frac{1496}{3} s = 498.66s$
