DID YOU KNOW?!?! When your dancing and you spin, if you are left handed, you are more likely to spin left, and if you are right handed you are more likely to spin right??
Try it! I hope this doesn't disappoint you!

Suppose that a cylindrical tank 6 meters high with a radius of 2 meters is filled to the rim with water. the tank is buried so that the top of the tank is 1 meter below ground level. the space above the tank is not filled with water. calculate how much work needs to be done by a pump to pump the water out of the tank up to ground level. (the water weighs 9,800 newtons per cubic meter.)
