If you have a trailer full of parekeets and they way 10,000 pounds but the trailer only has a capacity for 5,000 pounds, if you keep half of the birds flying would they still weigh 10,000 pounds? So do birds that are flying in a trailer still weigh the trailer down?

If a mountain top is closer to the Sun than the desert, when then is the desert hot and a mountain top cold? My guess is friction caused by the rays of the sun. Since there is less air pressure at high altitudes there is less resistance, therefore less friction to heat the surrounding air. Whereas the desert being lower altitudes with higher air pressure, greater resistance, longer distance/travel time, greater friction. Am I even close?

It is true that you are always exerting a force on the ground, and in turn, it is exerting a force back up to keep you in place. However, you can exert different amounts of force down on the floor, due to variables such as weight, location, etc; does the floor change the force it is exerting back up? It cannot stay the same for everyone, because then the floor would be exerting the same force to a sumo wrestler and a toddler... that would make the toddler fly up, wouldn't it?

If a person were to walk over one of a power plants pipes which contain the extremely hiehg pressure steam in which generates electricity they would be cleanly cut in half.
This got me to wondering is there any convinient way to make a gun that could use absolutely nothing besides tanks that you fill up before the use of the gun, didn't wiegh much more than heavier modern guns used today, and was without question lethal?
Well I don't mean to answer my own question but duh you can. A simple pump up BB gun is most the time lethal.
But eliminate the projectile and leave only the air to reach a target and kill. Would it be possible, what might you need for such a thing, and finally how far could this thing shoot before mixing with the rest of the air becoming worthless?
Sorry for having such a long question :-)
Thanks.

i understand that it evaluates how a measuring system varies due to repeatability and reproducibility errors. But is there a more in depth explanation to it? Also, what is the use of a C chart? would be better if there are sources.thanks
