Hen Mount St. Helen's erupted in 1980, it sent volcanic ash 18 kilometers into Earth's atmosphere. Which portions of Earth's atmosphere were contaminated by the volcanic ash?

Astronomical location of Mount St. Helen's is 46°12′01″N 122°11′22″O, meaning that such statovolcano is located at middle latitudes. In middle latitudes, troposphere is 17 kilometers high, which is below stratosphere, whose height is 10 kilometers at middle latitudes. Hence, the eruption of Mount St. Helen's in 1980 contiminated troposphere and lower parts of stratosphere due to volcanic ash.

the minimum amperage that the current in this wire would have to have so that its weight is completely supported by the magnetic force due to earth's field, assuming that no other forces except gravity act on it

a. vertically

explanation:

i tried it and took the test

if im wrong then we have different tests
