Answer:
Ozone creation occurs more than its loss
Answer:
A. The sound wave will reflect off Buildings and automobiles.
Explanation:
This is because the sound waves would more likely propagate through diffraction through buildings and transmission through the air. It is also more likely to be absorbed by buildings than for multiple reflections to occur off buildings and automobiles. In the process of reflection, these materials would absorb the sound energy thereby reducing its ability to reflect.
Answer:
4m/s approx
Explanation:
Step one
Given data
m1=71kg
m2=65kg
v1=3.4m/s
v2=??
We are required to find the Velocity of the second person
By applying the conservation of momentum principles
P=mv
m1v1=m2v2
Substitute
71*3.4=61*v2
241.4=61v2
Divide both sides by 61
v2=3.95m/s
v2=4m/s approx
The answer that best completes the statement above is COST-EFFECTIVE ANALYSIS. Occasionally, DUI checkpoints, also known as sobriety checkpoints are being established by police on the roadsides for safety purposes. This is also the same with the seatbelt laws. Both of these aim in decreasing motor-vehicular accidents. Comparing these two, we call it cost-effective analysis. When we say cost-effective, the effectivity of the action if being assessed in relation to the cost it takes to enforce the rule.
Part 1
When the solar atmosphere accumulates a lot of magnetic energy
to a point that cannot accumulate more, all that magnetic energy is suddenly released,
and with it, a lot of radiation. So much, that in fact it covers all of the
electromagnetic spectrum; from radio waves to gamma rays. That burst of
radiation is called a solar flare. In a single solar flare the amount of
radiation released is millions of times greater than all the nuclear bombs in
the face if the earth exploding together. Lucky for us, most of the high-energy
radiation dissipates before reaching the Earth, and the radiation that do reach
us, is deflected by the Earth’s magnetic field.
Part 2
1. Not all the radiation
of solar flares that reach the Earth is deflected by its magnetic field; some
of them reach us and charges the upper atmosphere with ionized particles. Those
particles react with the gases in the atmosphere and produce a light; that
light is what we call Auroras borealis or southern nights; One the most beautiful
natural spectacles in earth, who thought Auroras begin their lives as deadly
solar flares.
2. Solar flares
contain a lot of high-energy radiation that is extremely dangerous for our
electronic devices; when they reach the Earth, they can damage sensible
electronics like satellites. A very powerful solar flare could even damage all
the electronic devices on the surface of the Earth.
