Why do you need to balance the tube in the certifuge?

Otherwise the centrifuge will "tilt." So even if you want to work with a single tube, you must put another tube (with approx the same weight as the first tube) in the centrifuge and both must be opposite to each other.

When you put water in a beaker or test tube, you see a curved surface. With most liquids, the attractive force between the liquid and the container is greater than the attraction between the individual liquid molecules. So the liquid "sticks" to the side of the container. this is what is called miniscus.\n\nA few liquids have a "backwards" meniscus. An example is mercury. If you put mercury in a test tube, it would be higher in the middle than at the edges.

The chemical reaction to 'bond' two substances requires oxygen and the tube is "sealed" to keep most air out. It is not totally air tight however because if you let it go to long it will dry out in the tube. Also a little does stick to the inside but you never know it because you just assume the tube is empty and throw it out.

For the cork to sink it must raise the water level. Since it must raise the water against the force of the centrifuge - pushing harder on both just doesn't do the job (of sinking the cork).

If the tube is filled with water, when the tube is inserted water will flow from the upper beaker to the lower one by siphoning.\n\nThe pressure difference will be due to the weight of the water in the upper beaker that is above the surface of the lower beaker.

What it sounds like was that you didn't have enough air in the tube. When the pressure is too low, the tire & tube slide on the rim as you brake. The result is usually a cut in the valve stem or the valve stem can get completely cut away from the tube.  Rider weight does not affect the tube. If you're going to commute, go with a puncture or thorn resistant tube. It costs a little more, but is made from a heavier rubber and less prone to pinch flats & punctures. The "slime" filled tubes will usually stop small punctures but only make a mess when it comes to large punctures or cuts.

toothpaste r filled upside down , in which two or more equal pressure nozzles r filling the tube. then another machine closes the tube , so they will not mix

Centrifuge is used in purifying Uranium (U). When they get Raw Uranium, they need to purify it inorder to use that in Nuclear reactors.\nJust like you remove Butter from Milk, centrifuge uses the centrifugal force and centripetal forces to seperate pure U out of the ore.\nHTH

You can't balance it because you don't know what it yields.\n\n\nP.S. This needs to be in the chemistry category. You really must not know much about chemistry and physics.

Two different procedures. Tube tying they can be reversed and unravel When the tubes are burnt they are burnt and this is not reversible

You need a container that you can fill with water and put upside down into a bigger container with some water in(eg a 2-gallon catering container for ketchup or etc, upside down in a half-filled bath). You also need a length of tubing that can reach from outside the bath, to inside the upside-down container.\n\nBy taking a really deep breath, and then breathing out (into the pipe) as much as you can, you can replace some of the water with air that used to be in your lungs. As soon as you've finished blowing, put your thumb over the pipe to stop any of the air coming back out.\n\nWhile the container is still upside down and underwater, put the cap back on it. You can then take it out of the bath and either weigh it, or pour out the water still in it into a measuring jug.\n\nThe difference between its total capacity, and the amount still in it, is the same as the amount of air you breathed out.\n\nThis amount is NOT actually your total lung capacity; it's called the 'tidal volume', because you breathe it in and out like a tide. There's some air you can't breathe out, no matter how hard you try (your lungs are never totally flattened out, unless you died in an elephant avalanche). This remaining air is called the 'residual volume', and it's usually about half of what you can measure, ie a third of the total.

Its the ratio of the lengths.\n\nIts balance of angular momentum, so the length from the hinge and the forces exerted must be equal.\n\n10 N exerted upward at  2 cm from the fulcrum means that the downward load 2mm the other direction from the fulcrum is associated with a load of 100 N.\n\nYou may not have noticed, but there are special force concentrating deformations in the surface near where the tab presses.  That makes it fail at about 1/2 to 1/3 the load it would otherwise fail at.

When you have a pump, there is a stint that stays in you like with an IV, but the pump and tube itself can be removed if you're going to be active. You won't need insulin during love-making or any other physical activity. The stint is small and you can place it wherever you think is more comfortable - even your backside. When your activity is finished, you can just replace the tube in the stint and you're good to go.

Perhaps because it's easier to stick a pin in a blow up doll.  It's like the other day, I was having a bruski on the deck and this old broad came over and asked me for some duct tape and so she could place her feet on the ceiling and hang upside down. while watching the Honeymooners.  Can you beat that.
