I believe the three given sides should have been JK = 9, LK
=24, and LJ = 10. In this problem, you are asked to find the perimeter of a
triangle. To find the perimeter of a triangle, you will just add the
measurement of the three sides. So in this problem, the perimeter is 43 units
(9 + 24 + 10).

All of the above proposed methods are being proposed to help decrease global warming <u>but adding aerosols into the atmosphere does not involve the mitigation of the increase in CO2 in the atmosphere. </u>
1. Adding aerosol to the atmosphere - aerosols added to the atmosphere have the potential to block the sun's rays and reduce global warming. They reflect the sun's rays back to the atmosphere while at the same time providing "seeds" around which water droplets can come together to form clouds. Cloud formation can also help increase the earth's reflectivity against the sun's rays.
2. Injecting into geological formation - carbon dioxide from stationary sources (e.g. powerplants and factories) can be captured and eliminated from the atmosphere, compressed into a fluid state, and injected deep underground into permeable and porous geological formations and overlain with a layer of impermeable rock to seal the CO2 underground.
3. Adding iron to oceans to increase phytoplankton - phytoplanktons take up carbon dioxide from the atmosphere for photosynthesis. Thus, adding iron to the oceans, which acts as a fertilizer to the phytoplanktons, can encourage the growth of the phytoplankton population. The more phytoplanktons, the more CO2 that can be removed from the atmosphere.
4. Shoot it into space - some scientists propose that a conveyor can be built in the Arctic to take advantage of the Earth's magnetic field and allow for the venting or expelling of CO2 into outer space.
If a hot gas cloud is moving toward us, the frequency of the emission lines will be more elevated than those of a gas cloud that is inert or stationary.
<h3>What are emission lines?</h3>
Emission lines are indicative of a bright line in the spectrum of emission related to gas or vapor.
Thus it is correct to state that If a hot gas cloud is moving toward us, the frequency of the emission lines will be more elevated than those of a gas cloud that is inert or stationary. This is because gases expand as they get hotter.
