Yeah whatever, this week is an educational quiz where we all learn something. It is not like I am getting paid for being quizmaster.
It was daved that ran the quiz 2 weeks ago, Apparently airforcebiker won it but he had issues last week and it got aborted. I checked earlier with him and he had still not got his sheit together, so I had to take on the duties.
See posts #344, 345. Here's one for y'all. The gravitational pull of the moon on the oceans' water causes tides, right. The earth spins on its axis once every 24 hours. So why are there two high-tides a day?
moon is oneside of earth for 12hrs and the otherside for the other 12hr, water shifts round accordingly
The moon takes 27.3 days to orbit the earth, so if we're only looking at one 24hr period, you can assume it's more or less in the same place. It's the spin of the earth on its axis that results in the water being moved about, as different points on the surface become closest to the moon's 'pull'. Even then, why is there a bulge of water (high tide in that region) at the point on the earth's surface closest to the moon and a similar bulge directly opposite on t'other side of the planet? It's this second bulge that results in there being two high tides per (approx) 24hrs. Why the second bulge??? Edit: Daved, can you expand on your answer?
Well, I could. But, I think that getting into Centrifugal, Centrepital and Coriolis Effects is too deep, even or CGTI!
Ah ha! It's the water in the Marianas Trench that's deep. There are uber Trillions of litres of H2O in the trench. This compound weighs uber Billions of tonnes. Issac's #1 and #3 come into effect. Centrifugal, Centrepital and Coriolis forces are then applied. From Wiki. The bits in blue are my corrections! Guess what nationality the original author was? Billion: 1,000,000,000 - one thousand million, in the short scale (most common meaning in US English) 1,000,000,000,000 - one million million, in the long scale (seldom used in contemporary US English) Trillion: 1,000,000,000,000 - for all short scale countries - increasingly common meaning in US English language usage 1,000,000,000,000,000,000 - for all long scale countries - increasingly rare meaning in US English language usage but frequent in Real English and many other languages
I think Danster has us writing an eBay ad for him For this the contestants are henceforth charging 10 sausages per suggestion! I've seen KBA on a few wheels and I wonder if it is a meaningful marking? RG = RG Racing.
KBA RG TYP CLAY ET33 6Jx14H2 This data from the wheels, along with the pic is all the info I have. No ebay advert containing these wheels will be forthcoming.
