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:
There are three kinds of plate tectonic boundaries: divergent, convergent, and transform plate boundaries. ... A divergent boundary occurs when two tectonic plates move away from each other.
The Himalayas were formed by crumpling of plate edges in a convergent zone.
Answer:
geographers seek to understand where things are found, why they are there, and how they develop and change over time, also examining how human culture interacts with the environment, and they way locations and places can or have an impact on people.
