D bc i see a lot of people over there
Answer: Metal Detectors
Explanation: Metal detectors are inexpensive and easy to use equipment used to discover relics of the past. While it is useful in archaeology as a tool that discovers objects from the past quite easily, it is also a threat to archaeology. Some hobbyists and looters who come across archaeological finds which may be important to understanding past civilizations or a different era do not report these finds. Even worse, some looters knowingly infringe on archaeological sites and are aided by the metal detectors.
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:
igneous rock, would be lower
Explanation:
- As the composition of the magma depends on the ricks form which it was formed along with the condition of the melting, has a high level of iron, magnesium, and calcium, and is likely to be determined by the oxygen and the silicon.
- And virtually all the igneous rocks are derived for the magmas that are caused by the partial melting of the original rocks, either in the upper mantle o the crust.
- <u>The main mechanism, that meets the cracks in the zone is called the decomposition melting or the flux melting as the ricks are being moved to the surface. Thus magma continues to cool and the crystals start to form.</u>
Because we wont have water to drink or swim in or not be able to take a shower
