A blue flame is a manifestation that the combustion process is complete where there are no formation of carbon monoxide. On the other hand, a yellow flame represents an in complete combustion. Generally, a blue flame is much hotter as compared to a yellow flame so it heat things up faster. Also, it is a much cleaner flame as it does not produce soot which leaves a black residue on the material being heated.

What is the magnitude of the speed of a person at the equator due to rotational speed of the Earth?

notka56 [123]

The circumference of the Earth at the equator is listed as 24,901 miles.
So his speed is

   24,901 miles per day.

Convert it to units that we have a better feel for:

   (24,901 mi/da) x (1 da / 24 hrs)

   = (24,901 / 24) (miles/hour)

   = about 1,038 miles per hour.

You'll find a huge number of people on the internet these days,
telling you that you could not be moving at that speed and not
feel it, so therefore the Earth is not spinning, and it's not a globe.

I have a lot of feelings and comments about those people, their
lines of reasoning, and their levels of education and intelligence,
so don't get me started.

I just want to guarantee you that everything you're learning about
the Earth and the solar system in school is well founded, and it's
all based on the life's work of some of the smartest people of the
past 300 years of human history. Everything you're taught about
the Earth has good reasons behind it, whereas those other people
have nothing.

A person on Earth's equator is moving from west to east at roughly
1,038 miles per hour, relative to any point on the Earth's rotation axis.

The choices can be found elsewhere and as follows:

a. they are so small that they stay close to the ground due to the attractive properties of charged soil particles.

b. they are easily carried by the wind.

c. they easily dissolve in liquid droplets.

d. it is easier for then to roll along the small crevices in the ground.

I think the correct answer from the choices listed above is option B. Only the smallest particles of soil can be displaced by suspension because they are so small that they are easily carried by the wind. Hope this answers the question. Have a nice day. Feel free to ask more questions.
