Question:

Science help!!!!!!?

Formula is power work/time A weightlifter lifts a 1250-N barbell 2 m in 3 s How much power was used to lift the barbellA crane lifts a 35,000-N steel girder a distance of 25m in 4 s How much power did the crane require to lift the girder ? In kilowatts.

Answer:

wrap the foil around an object about the size you want the pipe to be, i.ea pencil for a narrow pipe, or a flashlight for a fatter pipeCarefully remove the pencil and presto! you have your foil pipe.for added effect, you can pinch one end, and at that end make a small crater and poke holes in the crater with a pin.
Pipe is not made of aluminum foilPipe is a rolling mill product, and aluminum is handled in a rolling mill the same way steel is handledThe most common method is to roll a long strip of aluminum into a U shape and then roll the edges over until they touch, making a complete circleThe edges can then be wrung or welded together to make a round pipeThis is just one of several methods for shaping aluminum into a pipeFor lots more information including pictures and diagrams, try an internet search on rolling mill or aluminum pipe manufacture or aluminum rolling millGood luck.

Core an apple at 90 degree anglesThen refrigerate itMake a tin foil bowl and perforate itYou get cooled smoke with a cinnamon flavor.
it's easier if you use a can or somethingJust poke a hole in the can and put the foil inside that to act as a bowl then inhale from the tab top.
