Apparently, the media has told us that when steel framed
buildings get very hot, they EXPLODE VIOLENTLY just like
in a controlled demolition, so that all their steel columns tear
apart over dozens of floors (even floors that were not on fire
can even explode??? Why?) converting hundreds of
thousands of tons of steel into shredded metal or red hot
motel metal for over 6 weeks, and turning very strong concrete
floors completely into fine powder EXACTLY like a well
planned controlled demolition!

Powerful stuff, this "jet fuel" (or kerosene); even just a few
small fires on a few levels, can TOTALLY LEVEL giant
skyscraper buildings! Take a look at the evidence that air
fires, fed by jet fuel, can completely pulverise skyscrapers,
without the need for any explosives!

Look at this proof that jet fuel air fire can MELT STEEL!

Amazing!

It's called "ultra," and is very concentrated. When the bottle gets low, I add water to use it all up. The first time I add water, it gets thicker, not thinner. Eventually, when it's almost gone, it acts like one would expect, and gets thinner when I add water. Can someone explain why?

When an object falls through air, there's a drag force (with dimension M * L/T^2) that depends on the product of the surface area of the object and the square of its velocity; i.e.,

F = C A v^2

where C is a constant.
The constant C has dimensions of _____

There are three vectors: A,B,C. Vector A is 70.0 units East of North creating an angle of 28.0 degrees. Vector B is 40.0 units West of North creating an angle of 56.0 degrees. Vector C is 46.8 units straight down South. Their magnitudes are given in arbitrary units. Determine the sum of the three vectors.

a) Give the resultant in terms of components.
Rx = 39.44
Ry = .....?

(b) What is the magnitude of the resultant?

What is the resultant's angle above the +x axis?
.......°


Please help me to do this question. I got Rx = 39.44 by using 70 cos 28 + -40 cos 56 + 46.8 cos 90

help me how to find Ry???????? please
and show me the work also..Thanks :)))))

5x2 - 5x + 1 = 0

if you could give an explanation that would be good :)

the 5x2 means 5 times x squared.

People say to gargle with warm salt water when you have a sore throat. I understand why this is a good idea if you have a bacterial infection, but does it help viral infections, too?
