Did you compare lakes in Siberia?

and a pic of it

Lake Titicaca in Bolivia, with its terraced farmed shores, it is the largest lake on Earth located at more altitude, 4.000 meters above sea level. Here as well as on numerous other places in the Andes mountains, various cultures flourished and disapeared during more than 2.900 years (1.400 B.C to 1.532 A.C.)

In the Banaue rice terraces in the Philippines, the irrigation system diverts water from rivers and streams, and channels these to the terraces through a series of dikes and pipes. ---quote--- The pipes is made of bamboo of various diameters, which make sure only the right amount of water is channeled to the terraces, and that no soil erosion is caused by excessive water flow. At the upper point of most terraces are well-preserved...

Miles per hour is a velocity, while pounds is (strictly speaking) mass. So the simple answer to your question is, no. Having said that, http://www.knmi.nl/samenw/hydra/faq/press.html provides a formula to translate wind speed to pressure: - quote - Pressure = ½ x (density of air) x (wind speed)^2 x (shape factor) * The density of air is about 1.25 kg/m^3. * The shape factor (drag coefficient) depends on the shape of the body. It has order of...

OK, I now have a rough estimate. Very rough. There are about 33 million Common Wombats. I arrived at that figure by taking the number of square miles in Tasmania, converting it to hectares, multiplying by the middle number of wombats per hectare (0.4), and multiplying that by 5 as an estimate of the Australian area with wombats on that map. This number could be off because of a number of factors, but, it is a reasonable number. There are about...

The Lost Colony is about The village of Roanoke, one of the first English colonies to be established on the soil. -quote- "Most Americans know the story of the “Lost Colony”. It dates back to the time the Europeans began to settle on this free land, that is now known as Virginia. The village of Roanoke was the one of the first English colonies to be established on the soil. However this village did not turn out to be that of a...

Hi Thanks for answering but you misinterpret my question as y'' + y' -y = 3*t instead of y"+y'-y=t^3 (this is cube and not multiplication). Please help me to solve by taking it as a cube

If you did manage to get a set-up without friction, then yes, after a push the block would move at a constant velocity until it hit something: this is Newton's first law. Source(s): http://en.wikipedia.org/wiki/Newton%27s_laws

The hydrogen experiment, the volcanoes with mentos, the soapy froth are all spontaneous types you can use - from the first link. The hot ice ( which others have suggested ) and the Make Ice Cream in a Baggie from the second link would also qualify
