Question:a have a science project And i have to do a song or rap about buoyancy and density. I really need help. Just a couple of lines or a whole song will be appreciated. please help!!! and answer quickly!!! the more rhymes and longer song will win an easy 10 points! thanks!!!

Answers:Longer doesn't mean better... remember that. I think you can come up with a good song if you talk about Buoyancy and Density as two friends who just can't get along... Some things they say to each other "Buoy!" (pronounced "boi") "You're dense!" (to density) I strongly suggest going with a rhythm they all know, like the Fresh Prince of Bel-Air!

Question:We need to do a science project and lab about buoyancy or viscosity. My science teacher told us to look online but I cant really find anything good. Help please! & links would be nice too (a)

Answers:Read and think know the meaning of both words get different fluids, water is easy, honey, liquid soap, motor oil try stuff, have fun clean up the mess afterward make a careful record of what you do, what you expect to happen, and what did happen that is why they call it YOUR PROJECT

Answers:There are only 14 million Jews in the world; seven million in the Americas, five million in Asia, two million in Europe and 100,000 in Africa. For every single Jew in the world there are 100 Muslims. Yet, Jews are more than a hundred times more powerful than all the Muslims put together. 8.1% of coupled households consist of unmarried partners, according to The State of Our Unions 2005, a report issued by the National Marriage Project at Rutgers University.

Question:Is it true about mountains that they balance the forces of gravity and buoyancy? Because they have deep crustal roots fixed in mantle. Do they balance the earth's crust in this way? I am not talking about earthquakes.

Answers:Tall mountains have deep roots. This is the Principle of Isostacy. Since mountains have thicker crust, they "float" on the mantle somewhat like an iceberg floats in the ocean. Since the mountains are not moving they are at equilibrium, which means the downward forces are equal (and opposite) to the upward forces. When crust thickens the underlying mantle is displaced. This is due to the plastic nature of the mantle, which is a solid that is able to flow in response to the placement of mountains. I could go into the mathematics of isostacy but I won't.
