Months back a couple of very close friends of mine lost everything they owned when their house burnt to the ground. All the remains have piled in the basement. Since they have had to move and don't have the time, they asked me to clean it up. I've cleared out almost all the big metal. Mainly what is left is a basement that has ashes about two feet deep and much broken and melted glass. They have offered me a reward if I can find a diamond that was in there, almost 3/4 carat. I have a good idea of approximately what area it is probably in. But how can I efficiently sift through all that ash and broken and melted glass to find it? I was told that diamonds show up well under a blacklight, but they couldn't even tell me what color they appear under a blacklight. And a lot of that glass shows up well too. Is there any way I can do this task with some sort of ease? I want to find it for them, but I don't have a year to sift through ash and the weather's gettin cold and it will snow soon.

I've heard that the water temperature of the North Atlantic on April 15, 1912 was -2°C (28°F) which is *just* above sea water's freezing point. Why was it still so cold in the middle of April? Is this normal? What would the sea temperature have been in February? If it had been any colder, wouldn't it be frozen? But the Atlantic never freezes at that latitude.

I clearly am misunderstanding a fundamental principal here. As far as I know sound needs a medium such as air or water to travel. While light only gets distorted by traveling though something. Yet I know that communication is space is possible.

So is it that the signal of radio is more like light than sound in that it needs no medium or am I completely lost on this concept?

sorry mates, the questions were mistyped, they should have been as follows:

1. simplify 3x +6 divided by ( x - 1)(x+2)

2. given that log10 to the power n minus log10 to the power m equals 2log10 to the power h. show that n equals mh to the power2.

3. simplify xsq minus 2 divided by x minus square root of 2.

thanks to all who have already answered.as to those who opt to call me names, i say, i do not mind.
