Sunlight reaches earth in 8 min. What is the distance between sun and earth?
(Light travels at a speed of 3 × 108 m/s)
Please explain fully
Answers
Answer:
144×10^6
Explanation:
The distance between the earth and the sun
d= velocity of light × time taken to reachlight form sun to earth
or
d=(3×108 m/s)×(8×60s)=144×10^9m
=144×10^6km
mark me brainliest plz if its helpful for you
Answer:
The average distance between the sun and the earth is approximately 93 million miles or 149.6 million kilometers. The time it takes for sunlight to reach the earth can be used to calculate this distance using the speed of light.
Explanation:
Light travels at a speed of 3 × 10^8 meters per second (m/s). To calculate the distance between the sun and the earth, we can use the formula: distance = speed × time.
If it takes 8 minutes for sunlight to reach the earth, we need to convert this time into seconds: 8 minutes = 8 × 60 = 480 seconds.
Now, we can use this time in the formula to calculate the distance:
distance = speed × time
distance = 3 × 10^8 m/s × 480 s
distance = 1.44 × 10^11 m
So, the distance between the sun and the earth is approximately 1.44 × 10^11 meters, which is approximately 93 million miles or 149.6 million kilometers.
Conclusion:
It's worth noting that the earth's orbit around the sun is not a perfect circle, but an ellipse. As a result, the distance between the sun and the earth varies throughout the year, with the closest approach, known as perihelion, occurring in early January and the farthest distance, known as aphelion, occurring in early July. Despite these variations, the average distance of 93 million miles is often used for calculations and general purposes.
