1) If any apparatus placed with in a hollow charged metal enclosure, why is it shielded from elctric field?

2) we always connect a negative terminla with a positive terminal right? or not?

Go back as far in time as you want. Even if the country has changed its name. (e.g.: Rhodisia--named after Cecil Rhodes--is now called Zimbabwe).

I'll have to try check how many there are myself, I am not sure.

Happy Thanksgiving, to those in the United States.

I read this in the Mattell Recall article today on Yahoo:

The CPSC said tiny magnets inside the dolls and accessories can fall out, and be swallowed by little children. When more than one magnet is swallowed, the magnets can attract each other, which can be fatal.

What happens exactly when two magnets attract each other and they have been swallowed? What makes it fatal?

Can anyone out there do this, because I'm really stuck?

The new cable and TV channel Channel#6 is keen to establish what opinion the viewing public have of its sunday night films. It has undertaken a survey of 100 subscribers and found that 70 like it and 30 don't.

Assuming a constant proportion (in the recent survey) of 70% liking the sunday films, how large a sample is required to detect at 99.5% level that the proportion of subscribers liking the sunday night films has risen from an earlier proportion of 60%?

I tried solving the problem by splitting the question in two parts. first card taking a red queen and second one a queen ( that is 5 cases) and the second part where the first card is the balance 24 cards (26 red less 2 red queens) and 4 queens leading to 24 X 4 96 cases. hence total 96 + 5 = 101 cases. Total sample space is 52 C 2 cases, but this does not give the right answer.

When you consider everything that you see as you look around, it becomes clear that you are being bombarded by a seemingly constant and infinite number of photons from every possible direction---not to mention any other massless particles that are NOT light. Any ONE particle will cause a pressure on contact, albeit barely there. But if you take into account the SUM TOTAL of such particles flying all over the universe, it wouldn't seem unreasonable that on a large enough scale that the SUM pressure exerted on any given object with mass may be large enough to result in what we see as GRAVITY. The amount of pressure this field of particles could exert would be dictated by the mass that these paricles hit. More mass, and the particles hit with a little more energy. Put a smaller mass next to a larger one and the acceleration caused by the larger mass will actually cause particles to push the smaller mass towards the next largest mass. The spacetime curve would be coincidental.
