The answer would be 21.6 but rounded up it would be 22J.
Alright I'm not an expert on this, so you'll probably have to verify it with someone more qualified, but here's my idea (the summary is underlined at the bottom, but I added an explanation just because):
Humans are increasing the CO2 levels in our atmosphere, trapping a lot of the sun's heat in. Increased heat increases the chance of desertification and drought, and also causes regional temperatures to go up. The sun's rays are also hitting the icecaps, but the ice itself reflects most of the sun. However, the ocean absorbs the heat, causing the water around the ice to become warmer, just enough to cause them to melt a bit. This melting makes the ocean level rise. <u>So to wrap up, humans are changing the biosphere causing the Earth to warm up, the icecaps and glaciers to melt, regional temperatures to increase, and the chance of desertification to also increase.</u>
It took me FOREVER to write and word this well so I hope this helps. =)
Answer:
An attractive force between the magnets. A is the correct answer if it was the north pole facing another north pole magnet the answer would have been a repulsive force between the magnets because the north pole of a magnet does not attract instead it separates from each other which is a repulsive force the best answer is A.
Explanation:
the southern pole of a magnet is a positive force while the northern pole of a magnet is negative .
Note: Magnet can attract each other only when they are facing the opposite directions a north pole will attract a south pole; the magnets pull on each other. But the two north poles will push each other away.
