What would happen if the world were to unite and detonate an ice-bomb (a bomb that freezes water) at the pole? Would that in any way help solve global warming? I would predict that the carbon in the atmosphere already would counteract the ice bomb, but is there any realistic way to reduce/reverse the effects of global pollution?

Scientists often look at other galaxies and by studing them in the telescope they seem to know what elements that galaxy mostly has.

So my question is are all the elements in the known universe been found or are they using the current knowledge we have on elements to make this prediction?

Compared to solids and liquids, the particles of gases are very far apart. Because of the significant amount of space between particles, gases are easily compressed.

Using what you know about the compressibility of gases, explain why oxygen in a SCUBA tank is compressed.

On November 6, 2007 a child in India had an operation to have two extra legs and two extra arms removed. She was born that way because she was in the womb with a twin. The two of them grew together. The local population considered her the manifestation of a goddess. Her parents named her after the four-armed Hindu goddess of wealth. Science understood exactly what caused the phenomenon and the medical profession fixed it. 75% of the population on this planet believe in some sort of supernatural or spiritual deity.

Why do so many intelligent people on this planet fail to realize the parallels of human behavior that are witnessed so often is proof of the human gullibility of believing in supernatural things like, God and other superstitious phenomenon, such as the little girl that I described. Instead, human beings throw out common sense for the sake of ignorance and then preach superstition as being fact.

How dangerous is this to science and to our existence?

Consider two mass, 3.2kg and 7.1kg, connected by a string passing over a pulley having a moment of inertia 11gm^2 about its axis of rotation. The string doesn't slip on the pulley, and the system is released from rest. The radius of the pulley is 0.33m.

Find the linear speed of the masses after the 7.1kg mass descends through a distance 33cm. Assume mechanical energy is conserved during the motion.

PLEASE PLEASE HELP!!!!

Winter is approaching and everytime the temperature drops, I get more prone to being electrocuted from static buildup while driving my car. And when I say electrocuted, I really mean it. It's very itensive. Obviously, it has to do with my rubber soles, but how can I avoid getting shocked ? or What techniques do you use to avoid getting shocked when you notice the buildup of static ?
