Ok, so I need to figure out this problem involving air pressure for a story I'm writing. In my story, there is a building that is 777 stories tall (lit. 781+) ie. 2087 m or 6260 ft. Now I need to find out at what floor or height the air pressure would become so much that you couldn't breath, or could even die. And also the air pressure at the top.

If you know any good air pressure solutions, that would be great too.

Also, if any extra info is needed to solve this, I can supply it.

Thanks!

A sundial clock indicates time at the current rotation of the earth around the sun. There is no way to reverse a sundial unless you reverse the rotation of the planet thereby reversing time. Thus, in order to reverse time you would need to create something that can spin in a counterclockwise motion faster than the earth's. Likewise you would have to create something that would spin in a clockwise motion faster than the earth's in order to exceed time or go to future.

What do u think if we had the technology to build a machine that would do this will it work?

Is it possible the calculate the result of containing an explosion in an indestructable container, and then measure the resulting pressure in lbs per square inch. say 1 kilo of semtex in a container of volume 1 cubic metre with a wall thickness of sufficient thickness to contain it ( say 1 metre thick ) Im just curious in trying to get a feel for the amount of energy involved. I think I read somewhere that in the alamo project It was considered to try and contain the first experimental atomic bomb and explode it inside a container

10.Several days after a snowstorm, the roof on a house is uniformly covered with snow. On a neighboring house, however, the snow on the roof has completely melted. Which house is probably better insulated? Give your reasoning.
11.One car has a metal body, while another has a plastic body. On a cold winter day these cars are parked side by side. If you put a bare hand on each car, the metal body feels colder. Why?
12.A high-quality pot is designed so heat can enter readily and be distributed evenly, while the rate of energy loss from the pot is kept to a minimum. Many high-quality pots have copper bases and polished stainless steel sides. Based on conduction and radiation principles, explain this design is better than all-copper or all-steel units.
13.A concave mirror can be used to start a fire by directing sunlight onto a small spot on a piece of paper. Explain why the mirror does not get as hot as the paper.
