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>
To answer this question you will find the volume of the cylinder and the volume of a cone and divide them in that order.
Anders will need 2 cone containers filled with plaster to fill the cylinder cast.

Answer:
Option (1)
False
Explanation:
The mid-oceanic ridge is one of the main features in the divergent plate boundary. Seafloor spreading takes place along this ridge, where the lithosphere becomes thin because of the uprising magma. The magma erupts at the surface forming a ridge which is commonly known as the mid-oceanic ridge.
As the magma melts at this ridge due to the decompression process, it solidifies and forms young basaltic igneous rocks. These are geologically the youngest rocks. With the increasing distance right from the mid-oceanic ridge, the age of the rocks increases.
Thus, the correct answer is option (1).
At this mid-oceanic ridge, when the magma erupts at the seafloor, it is comprised of magnetic minerals, which shows a specific pattern in the orientation of the earth's magnetic polarity. This forms alternate stripes, that starts from the mid-oceanic ridge and eventually expand outward. This pattern of earth's magnetic polarity is found in all the mid-oceanic ridges on earth.
Hence the given statement is false.
China and India are definitely in the top three, as they both have over a billion of people (China still more but India is about to catch up). Number 3 is actually the US! so it's China India and the United States
