[QUOTE=exceltoexcel,Dec 2 2005, 11:59 PM] ICrazy I was talking about how cold water boils faster, can anyone expain this to me.

 

the plane would take off no problem.

THink of it this way - pretend its a perfect world and the bearings in the wheels were 100% perfectly efficient.

The plane is sitting there on the conveyor belt, everything turned off and standing still.

Now turn on the conveyor belt - what would happen to the plane? In a perfect, frictionless bearings world, the plane would remain still, but the conveyor belt would move underneath the spinning wheels.

Now flip on the engines, the plane would now move forward.

Now in the real world, there is friction on the bearings, so the plane would start to move backwards at first. But the engines produce much more thrust forward, than the bearings creating friction backwards. Hence, take off.


Its simliar to this question: If you hover a helicopter in the same spot, will the earth rotate underneath you?

 

As a helicopter pilot, I can say NO.

Okay, it WILL rotate, but the helicopter rotates with it.

 

define "same spot." If you let the earth "rotate underneath you," you would not be hovering over the same spot, methinks.

 

Just like a redneck wedding...It's all relative!

 

So is he

 

But do they still serve those crappy peanuts during the 'flight"?

 

That's not quite correct. It's true that in the general case colder water freezes before hotter water, but due to the Mpemba effect, sometimes hotter water can freeze faster than colder water.

 

People that don't get this plane thing make me go . I guess as long as they eventually get it, it's okay.

 

no, smaller volumes of warmer water can freeze faster than larger volumes of colder water, but it is incorrect in any sense to suggest that the hotter the water, the faster it will freeze.
