Why is it that when you place a test tube over a burning candle in a peatree dish with water, that the candle goes out and then the water from the dish rises into the test tube. Mainly what are the reasons that the water rises. I am kind of going with the "temperature and pressure are related"...

Few weeks ago there was that huge fire in a high rise tower in Caracas/Venezuela,does that building collapsed?

[FONT=Garamond]undefinedundefined I am in the process of planning my Coursework, I’m investigating rise and run; the time taken for a trolley to slide down a slope with varying distances from the end and with various inclinations, and I’ve hit a wall, a problem... I'm looking for a formula...

A tennis player standing 12.6 m from the net hits the ball at 3 degrees above the hoizontal. To clear the net, the ball must rise at lease 0.33m. If the ball just clears the net at the apex of its trajectory, how fast was the ball moving when it left the racket? would it just be...

the sloping side is frictionless, it is spun at constant speed by rotating the wedge. show that when a mass rises up the wedge a distance L, the speed of the mass is v=sqr(gLsin0) I got Fx=m(v^2/r) = mgsin0 v^2=g*sin0*r can I say r=L ? I got stuck, could you give me some hints thank you

I am not a physics person. I am a lawyer. So bear with me: I do not understand why the temperature of a gas or a liquid increases with pressure. I understand the Ideal Gas Law of PV=nRT, and I understand it mathematically, but I do not understand conceptually what is happening at the...

This is a thought experiment question. I have three air molecules. Two have the same speed. The third is faster than the other two. When they slam against each other, they keep their previous speed after the rebounding acceleration. I put them in a container. I hold them from wanting to...

I am passing Xamps thru a Ylenth of conductor for time t sec. can anybody suggest me how to calculate temperarure rise in the conductor after time tsec in a conductor

Why does hot air rise? What I'm really getting at is why should the speed of kinetic motion of the individual atoms of heated air rise compared to it's slow moving neighbor, is it merely because it bounces around more often and so all air competes for dominance upward such that the fastest...

[SOLVED] Beyond Babylon: Europe's Rise And Fall "Do not think that I came to bring peace on earth. I did not come to bring peace but a sword" (Mat. 10:34). That bold statement of Jesus the Christ knocks down all the traditional images of "God with us." Jesus declared WAR - not peace - on...

Hi, I would appreciate help with the following problems: 1.) A diving bell in the shape of a cylinder with a height of 1.00 m is closed at the upper end and open at the lower end. The bell is lowered from air into sea water (p=1.025 g/cm^3). The air in the bell is...

If anybody else has had problems with Rise of Nations can you please refer to my post in the Software section.

Hmmmm, i have a slight problem with RON i have recently purchased the game and have as of yet not been able to get the damn thing to play, it appears to have installed onto the computer fine without any problems but when it comes to playing the game all i can do is watch the Intro and then it...

The Rise of Science by Ted Tripp We have already noted that education in the 14th and 15th centuries was dogmatic due to a shortage in books which forced reliance on scholasticism. The unique nature of our Earth formed one of the corner-stones of orthodox Christianity, so that anyone that...
