mote1985 [20]3 years ago
7 0

Explanation:

^{41}\text{Hi}: 41.000\:\text{g/mol}×0.283 = 11.603\:\text{g/mol}

^{42}\text{Hi}: 42.000\:\text{g/mol}×0.429 = 18.018\:\text{g/mol}

^{44}\text{Hi}: 44.000\:\text{g/mol}×0.288 = 12.672\:\text{g/mol}

Adding all the weighted values on the right hand side, we get

\text{Hi}: 42.293\:\text{g/mol}

the motion of a particle along a straight line is represented by the position versus time graph above. at which of the labeled p
atroni [7]

Point A has the largest magnitude of acceleration as compared to other points on the position verses time graph.

On the graph, A is the point where magnitude of the acceleration of the particle is greatest as compared to other positions on the graph because the height of point A is the largest as compared to other points of the graph.

The graph shows at which point acceleration of an object is higher and lower so we can conclude that point A has the largest magnitude of acceleration as compared to other points on the position verses time graph.

What do changes in the biosphere, rising sea levels, drought and desertification, regional changes in temperature, and melting g
horrorfan [7]
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. =)
