Radius of earth as given in question = 6400 km
Height of the air balloon = 200 m
= 0.20 km
Now
Let us assume the distance up to which one can see from the balloon = d
Then
d=sqrt [<span><span><span>(R+h<span>)2</span>−<span>R2]
</span></span></span> = sqrt [</span><span><span>2Rh+<span>h^2]
= sqrt [2 (6400 * 0.20) + (0.20)^2]
= sqrt [(2 * 1280) + 0.04]
= sqrt [ 2560 + 0.04]
= sqrt [2560.04]
= 50.6 km
A person in the balloon can see up to a distance of 50.6 km. I hope the answer has helped you.</span></span></span>
Answer:
We can have more information about the past better right now than in later times.
Explanation:
Our technology has improved so we can learn about things better than ever. For example, we can learn more about ancient times or get more information on cells using more imporved microscopes. Hope this helped! PLease mark me brainliest! :D
