Answer:
Standard Form = 150 Million or ( 15,00,00,000)
Step-by-step explanation:
Speed of light = 3 x 108 m/s
Time taken by light to reach the Earth = 8 min
= 8 x 60 s
= 480 s [∴ 1 min = 60 sec.]
We know that,
Distance = Speed x Time
= 3 x 108 x 480
= 1440 x 108
= 1.440 x 103 x 108
= 1.44 x 1011 [∴ 103 x 108 = 1011]
Hence, the distance of Sun from the Earth is 1.44 x 1011 m.
Standard Form = 150 Million or ( 15,00,00,000)
