Answers
Answer:
Explanation:
The statement 'The distance of a star from the earth is 8.33 light minutes' means that the light from the
star takes 8.33 minutes to reach earth.
Given
Speed of light $=3 \times 10^{8} \mathrm{m} / \mathrm{s}$
Distance covered in $1 \mathrm{sec}=3 \times 10^{8}$ \ m
Time taken $=8.33 \mathrm{min}=8.33 \times 60 \mathrm{s}$
Distance $=\operatorname{speed} \times \operatorname{time}=3 \times 10^{8} \times 8.33 \times 60=1.5 \times 10^{11} \mathrm{m}$
Answer:
The distance between the star and earth is 14994m
Explanation:
Light minutes means the distance covered by light in 1 minute
1 min = 60 s
In 1 s light travells 3×10 ^8
In 1 minute it is 3×10^8 ×60
=18 ×10^9 meters
Given time taken is 8.33 minutes
Distance = speed ×. Time
= 18×10 ^9 × 8.33
=14994×10 ^7 meters
