Physics - June 2006

Plz explain the theory using own words as simple as possible. It will be better if u illustrate the theory with simple example.

A solid conducting sphere with radius R carries a positive total charge Q The sphere is surrounded by an insulating shell with inner radius R and outer radius 2R The insulating shell has a uniform charge density p (p stands for rho)
Find the value of p (rho) so that the net charge of the entire system is zero

There is a concept that there are different vibrational levels/speeds of the matter in the universe, often called layers, planes, or more accurately densities. It's like having different layers in Photoshop. They reside in the same place, but they are different 'layers' or 'planes' , and you can view them separately.

Alot of people confuse the concept of densities with that of dimensions (the norm length-wide-height, or 1st,2nd, 3rd). It's like confusing x and y pixels with the layers. The two concepts are often fused or used synonymously, despite being very different, probably making it very confusing for those unfamiliar with densities.

My question is how many people understand the difference between these concepts?

I suspect a hydrogen-as-fuel "solution" to our modern energy problems is an illusory dream. Will costs of extraction and _safe_ distribution and use ever be econimically viable? At any rate, I strongly suspect ill-advised "leaders" touting it haven't bothered to ask the right questions of the Physicists. Can anyone shed real honest light on this issue?

well i know that the future is undetermind so travel to the future would be impossible, but if a person could travel backward in time, how would the expansion of the universe affect time travel, would the person traveling back in time become more dence on a molecular level the farther back he goes, because doesn't the expansion of the universe cause the mass of the universe to expand with it, would time travel to the past be like being in a black hole.

Sometimes I want a cold bottle of beer fast! So I put it in the freezer instead of the refrigerator. It takes about 30 mins to make a beer cold but sometimes i forget about it. Several times I've left the beer in the freezer for an hour or more. The beer is very cold but not frozen solid yet. I get it out of the freezer and its still all liquid. I can see the bubbles moving around when I move the bottle. I then leave it on the table. However when I return a few minutes later i find the beer is frozen solid!!! The beer can't have got any colder can it? Surely it can only get warmer outside of the freezer? I can't figure out why this happens. The only thing I can think of is maybe its something to do with the condensation that forms on the cold bottle after I remove it from the freezer. Can anyone answer this for me?

Generally, in small amounts, how much does liquid nitrogen cost at retail? Perhaps a liter.

Specifically, is there an equation that can relate torque (t) required for a dc motor to power a toy car with total weight (c), two wheels each weighing (w) with radius (r), gear friction (g), surface friction (s) between the wheels and the surface, at a velocity (v)?

was driving down the freeway and had a small leak that left a trail of gasoline on the road behind him and it accidentally caught fire 100 ft. behind him going at a speed of 45 mph. How fast would the driver have to drive for the flame not to catch up. (variables: sunny, 72 degrees F, 45% humitiy, pressure: stable, flat road, and the truck leaked an average of 1 gallon per minute.) I dont know if this is enough info to solve a problem like this. Let me know if you need any more info.
