How much does it cost to install a central air conditioner per sq foot
There is really not much you can do about it.
you will probably will require 10 AC 5000 sq feet room
this is a pretty good party trick. tip your head back and pucker your lips, then blow out to make a strong stream of air straight up. then place the ping pong ball in the air stream and it will float! tip: keep the air stream strong and constant and you should be able to keep it up for 4-5 seconds before gravity takes over.
you can.
you need a 100 foot tall crane with thin wires in broad daylight
None at all.
No a train does not float in the air, no train does.
None, since there can be no conversion.A cubit equals 1.5 feet so a cubit foot equals 1.5 square feet which is a measure of area in 2-dimensional space. The amount of air breathed requires a measure of volume in 3-dimensional space. The two measures are different and, according to basic principles of dimensional analysis, any attempt at conversion from one to the other is fundamentally flawed.
Objects filled with air float on water because the density of air is much lower than the density of water. This creates buoyant force, which causes the object to float. The air-filled object displaces an amount of water equal to its weight, allowing it to stay afloat.
Float On Air 010a13d7
Everything I can find says that a cubic foot of air can lift about 62-63 lbs.
The float has air in it.
Only in water. The air from your mouth is the same density as the air in the room- they will not float in air.
1 cubic foot of air will support 62 lbs
Because it has air in it. Air weighs less than water therefore air floats.
Balloons float when they are full of air because the helium or air inside is less dense than the surrounding air, creating buoyancy. When they are deflated, the balloon is denser than the surrounding air, causing it to sink rather than float. This is due to the principle of buoyancy and the difference in density between the balloon and the air.
