Science & Mathematics - 6 February 2007

Let's clear some things up first:

1) Scientific records of average global temperature only started in 1880.

2) The 'little ice age' started about 550 years ago and ended in the mid nineteenth century (hence the world started to naturally warm up at the same time as temperature records were beginning to be taken) - i.e. the world was colder than normal at the beginning of the readings.

3) In 1883 Krakatoa errupted, spewing tonnes of soot into the atmosphere and blocking out the sunlight for a substantial time, such that the average global temperature dropped by up to 5 degrees centigrade. The atmosphere was only clear enough to begin increasing the average global temperature again in the mid twentieth century.

Just these three facts can clearly show how the world is warming up back to its NORMAL AVERAGE TEMPERATURE and, consequently, isn't the result of our carbon dioxide usage. In fact, the amount of carbon dioxide we release is tiny compared to what is naturally released

Having been once again looking at the millions of articles about heatsinks and the likes for computers I was wondering that, under intense thought, does the brain heat up like a microprocessor or is it designed not to? Either way why not/so?

Just a bit of light hearted stuff:

If it snows all over Britain on Thursday as is predicted by the weather people lets have a guess game how long it will snow and how long it will last.

I predict it will snow for 4 days and nights and last on the ground for a week.

What you think ?

please solve this using the law of conservation of momentum...



a 0.02 kg ball moving to the right at 0.25m/s makes an elastic head on collission with a 0.04kg ball moving to the left at 0.15m/s after the collission, the smaller ball moves to the left at 0.16m/s. what is the velocity of the 0.04kg ball after collission?


please with solution...use the law of conservation of momentum...thanks
