Liquid roof is a roof coating.
Nope. I have a sippy cup. It has a lid on it. Any intelligent individual, WOULD have a lid on their soda, water, or whatever they may be drinking, when driving.
Not sure but most likely not. Lighning is just electricity, but because it changes the states of elements it is possible that it is a side effect. If you believe in UFO's being alien. Then you are contradicting religion. Not that Believing in God makes you religious. But the whole bible says we are all that is and the universe revolves around us. It doesn't say that in the beginning God created the universe and other planets with life. It says god created earth and in 7 days it was finished. The government would loose control and so would religion if they admitted all the knowledge about UFO's. You must be evolving. They are going to become very popular in a about 5 years. When they make a public appearence. we will greatly need their help when they come, because earth will be a very different place. 2/3 of the population will be gone and the earth will need new geography books. Lands will appear and others will dissapear. Hang on tight. 2009 is the year.
A fireman, 47.3 m away from a burning building, directs a stream jet of water from a ground level fire hose at an angle of 34.4 degrees above the horizontal. The acceleration of gravity is 9.8 m/s2 If the speed of the stream as it leaves the hose is 36.9 m/s, at what height will the stream of water strike the building? Answer in units of m. . D 47.3 m g 9.8 m/s^2 Vinitial 36.9 m/s θ 34.4° . V horizontal initial V cos 34.4° V horizontal initial 36.9 * cos 34.4° V horizontal initial 30.45 m/s . V horizontal is constant Distance horizontal V horizontal initial * time 47.3 m 30.45m/s * t t 47.3m ÷ 30.45 m/s t 1.55 seconds .
