Q: An air core is no core except air.: The purpose of a core in a transformer is to ensure as much as possible of the flux from one winding links the other. Also, we want the core to have a very small reluctance, so that the magnetising inductance (sometimes refered to as the mutual inductance) is very large. If it isnt, the transformer will have a large magnetising current i.e. it behaves as a shunt low value inductance, we need this inductance to be very high. Even if the powdered stones in the tube had a low reluctance (maybe they have alot of iron oxides in them?), the problem is that still most of the magnetic circuit is through air, so there is still a high reluctance. You need a closed magnetic circuit with a low reluctance material, or else you will need a very large number of turns on the windings, and they will need to be arranged carefully, to keep the leakage inductance low (flux from one winding that doesnt link with the other...) But what is the application? For low frequency power transformers we want a low leakage reactance and a very high magnetising reactance. For other kinds of transformers we might want a high leakage reactance (say a transformer to be used as a welder, the leakage reactance acts like a series choke to limit the short circuit current...). For broadband high frequency transformers, we want as little leakage inductance as possible, where as low magnetising inductance is not a problem at these frequencies. So usually we make transformers for this application with the two windings as one side of a twisted pair cable, or coax cable, and then have an air core. So how good a transformer core is depends on its application!

Q: A very small uniformly charged plastic ball is placed on top of another in a test tube, as the figure shows: http://bildr.no/view/1194610The balls are in an equilibrium situation with a distance d from each other. If the charge on each ball is doubled, the distance between the balls in the test tube will be;A) √(2d)B) 2dC) 4dD) 8d: The balls are in an equilibrium situation with a distance d from each other. If the charge on each ball is doubled, the distance between the balls in the test tube will be; The top ball is suspended in the air, so the net force is 0 N. This means the electrostatic force is equal to the weight of the ball. Fs = m* g Fs = k * q1 * q2 ÷ d^2 k * q1 * q2 ÷ d^2 = m * g d^2 = (k * q1 * q2) ÷ (m * g) d^2 = (q1 * q2) * [k ÷ (m * g)] d = √(q1 * q2) * √[k ÷ (m * g)] √[k ÷ (m * g)] is a constant. So, the distance between the 2 balls is directly proportional to the square root of the product of the charges. Let’s double the charges and see what happens to d d = √(2q1 * 2q2) * √[k ÷ (m * g)] d = √(4 * q1 * q2) * √[k ÷ (m * g)] d = 2 * √(q1 * q2) * √[k ÷ (m * g)] Doubling the charge, doubles the distance! the answer is B = 2 * d

Q: What's the function of the plastic tube in this crown beam?: Because the screw to pass through the concrete cover, casing, Chaimo screw can be conveniently taken out. The exposed part of the tube will eventually be removed, and the tube will be poured into the mortar to smooth it out.

Q: Can plastic tubes be used for fuel transportation?: Yes, plastic tubes can be used for fuel transportation. Plastic tubes offer several advantages such as flexibility, durability, and resistance to corrosion, which make them suitable for transporting various types of fuel. However, it is important to ensure that the plastic material used is compatible with the specific fuel being transported and complies with safety regulations to prevent any potential risks.

Q: If a kid has to be intubated due to a respiratory infection, what do they do? Do they keep you asleep until you can breathe on your own while you're intubated or can you be awake while the tube is in? How long do they usually leave it in? How do they put it in if you're in respiratory distress?: When someone needs to be intubated, they place narrow plastic tube down into their throat, just above the patients lungs. This can be done in respiratory distress. How long the tube stays in place all depends on how sick the patient is. That can be days to weeks. The patient is usually sleeping to help them breath more easily with the ventilator, but if someone is able to remain comftorble, they may allow them to be more awake.

Q: i was wondering what would cause oil to lightly spray out of the plastic tube that hangs down out of the top end of the piston. the tube comes out of the top end right before the exhaust header bolts onto the piston.: The link doesn't work - session is timed out. Always give year, make, engine size and model # when asking questions. We need all of that info to give an informed answer. I know what tube you are talking about. That tube is the breather hose for the power valve. As the piston rings start to ware, the oil in the premix doesn't get fully burned and accumulates on the power valve and lt's linkage. The engine is probably overdue for a top end rebuild and power valve cleaning. Remove the cover to see how much crud is in there. 2 stroke engines require rebuilds quite often, to prevent damage to the cylinder. If the top end is fresh, remove and clean the power valve. Otherwise clean the valve and replace the piston rings.

Q: I mean, like filling a plastic tube from end to end with mercury, sealing it with caps that allow contact points at either end, and then wrapping the tubing around a ferrite core, and adding current. Would this function just like any other coil?: Interesting question! When a current flows through a conductor an electromagnetic field is generated. If the conductor is formed into a coil the field is concentrated. If you put a ferrous (iron) bar through the center, it should have a magnetic field ( attraction). It would be an electromagnet I think: Michael

Q: im making a light bulb vaporizer and on the top im sticking a plastic tube into a cork and i wanted to know if the vapor from the weed is hot enough to melt the plastic in the tube, and obviously plastic fumes are toxic so i wanted to know if thats safe. if not, is rubber tubing any safer? or would the vapor melt that too? dont tell me not to smoke, i get it how its bad for you: It's a great source for more information about the many benefits of portable herbal vaporizers.

Q: Does the PVC-U drain plastic pipe need to be fabricated and installed?: PVC-U drainage plastic pipes shall be calculated for the installation of the pipe. The support shall be determined according to the laying method, drain pipe diameter, and the circumstances and location of the special placement.
