ohhungry Posted August 10, 2013 Share Posted August 10, 2013 First correct answer wins an astounding 1 gold coin. A man is doing a science experiment in the Arctic. His experiment involves determining how much power it takes for different drills to dig a hole through the ice to a depth of 5 metres. He has 3 different drills to test. The first one is 5 meters in length, with a radius of 2 metres at the base, and makes an angle of 40 degrees from the centre of the tip to the base of the drill. The second one is similar, but instead makes an angle of 30 degrees, and the third an angle of 20degrees. Each one uses electrical power (created by a generator and solar panels) based on the ratio of the angle (in radians) to the radius of the drill. The scientist must decide which drill uses the least power, but before he starts, he sees a bear walking towards him. What colour is the bear?

Alterego101 Posted August 10, 2013 Share Posted August 10, 2013 The bear is white because you don't get bears in the Antarctic. (Polar Bear) Quote Link to comment Share on other sites More sharing options...
