A building is in motion after being impacted, and is leaning; since to stop an equal force requires an equal force, of equal mass, according to Newton's 3rd Laws of Physics, and you do not have an equal sized building to stick in the way of the falling building, do you stop the building in motion with a compression resistant or a tension resistant object?
And how.
There is an answer to this.

A solid of density 5000 kg/ m3 weighs 0.5 kgf in air. It is completely immersed in water of density 1000 kg/ m cube. Calculate the apparent weight of the solid in water. What will be its apparent weight if water is replaced by a liquid of density 8000 Kg/m3?

Guys please help me solve this.....the answers are:
1... 0.4 kgf
2...Zero

Though I know the answer I still need to know how it works....please help me!

Basically im confuzzled on how to solve problems that involve Wet Gases and then turning them into dry gases and then asnwering questions about them..

For example they give you:
a 1.6 sample of KClO3 is heated and reacts in thsi way
they give you a reaction
Then they say what is the volume of oxygen collected over water at 26C and 740Torr.....

Like how would u go about doing that...No i am not looking for the answer, simply how to solve it....I kidna wasn't paying attention in class lol

i know there is a way to solve this equation.but don't know the way :D
please help me.
the function is really simple [!!] :
x + x * ln(x) +a*x=2
solve it for x (we know the value of a)
ln=natural logarithm
thank u very much.

I am a Floridian and have never been exposed to any kind of cold weather less than about 60 degrees. I am going up to North Carolina in a couple of days and I am completely in the dark about what to wear for that kind of cold weather. (It is snowing)
What kinds of clothes should I buy? and any ideas on where I can get them?

Small particles have smaller particles in orbit around them. Doesn't it follow that we are but a small particle floating around another massive one?

Ok,before you get hyped let me tell you,last night i watched this one show on the science channel on "Doomsday on 2012:life after the impact"or something along those lines.Personally i think its bullshit because in 5 years everythings just gonna become disingrated from this damn comet?But at the same time it scares the blood out of my bones because all these notorious scientist that work for NASA and such all agree to the conclusion that this will in fact happen in 2012 if they can't stop it[which is very rare]My death wish is not including a giant meteor creamating me.What do you guys think?
