What is the squiggle line called on the y axis of a graph?
When you are changing a scale on a graphic, you warn the viewer by using a squiggle line on the changed axis. If the bar is unusually long, the bar length is compressed with a squiggle in the bar itself.
Why can't a swimmer snorkel more than a meter deep?
"Because the pressure will cause the heart to explode." Well, no (the heart cannot "explode" anyways, rupture yes, but I'll leave it at that for now). The main problem is the pressure differential on the surface compaired to the lungs which are submerged. At one meter's depth the water adds 0,1 bar of pressure to the atmospheres 1 bar. This means that the lungs which are compressed to 1,1 bar (1 bar ATM and 0,1 bar of water) must overcome the pressure, making breathing impossible since the air cannot be drawn into the lungs.
Why is a rigid bar that rests on a fixed point called a fulcrum?
