Answer:
Space junk can damage satellites and can be lethal to astronauts.
Explanation:
Most of the object considered space waste are very small and travel around the Earth at high speed. Because of this, they can be dangerous for launch vehicles, satellites, the International Space Station and any manned mission should they collide with a spaceship.
The plan proposed by Roosegaarde to reduce space junk starts with a public awareness program that helps inform the public about the reality of space junk.
The eventual plan to end the space waste problem is to upcycle the debris floating around the planet. I think with the use of new technologies it will certainly be possible to eventually eliminate space waste.
The increase in trade and commerce during the middle ages resulted in the increase of the growth of towns and cities.
Answer:
V ≈ 4577.204 cm^3
Explanation:
Use the volume formula V=4/3πr^3 to find the volume. Since you need the radius but are given the diameter, divide it by 2 to get half.
21.4/2 = 10.7
Now plug that into the formula and solve:
V=4/3πr^3
V=4/3π(10.7)^3
V= 4/3π(1,092.7272)
V= 4/3 * 3432.903
V= 4 * 3432.903/3
V = 13731.614/ 3
V ≈ 4577.204 cm^3 or whatever unit is stated.
Carbon dioxide (CO2) makes up the vast majority of greenhouse gasemissions from the sector, but smaller amounts of methane (CH4) and nitrous oxide (N2O) are also emitted. These gases are released during the combustion of fossil fuels, such as coal, oil, and natural gas, to produce electricity.
