Race Definition and 215 Threads

Hi, I just needed help starting off this problem: "A 1-km racetrack is to be built with two straight sides and semicricles at the ends. Find the dimensions of the track that encloses the maximum area." There was a similar question which I did before this which involved a Norman...

If four cats and five mice enter a race, how many ways can they finish with a mouse placing first, second, and third? I was about to say that the answer would be P 9, 5 but not sure...

Genetic basis for "race"? Now, I'm not sure if "race" is in any way a proper term in biology. However, I've seen a few threads here and there by Carlos Hernandez, and now I'm curious. There are differences among humans based on where we, and our ancestors, are from. Average heights...

Brain scan 'identifies race bias' A brain scan that can apparently root out racists has been developed by scientists. The technique was used on white volunteers shown photographs of black individuals. Complete text at...

What you all think about China joining the space club with their scheduled space launch next week? http://story.news.yahoo.com/news?tmpl=story&cid=624&e=1&u=/ap/20031010/ap_on_sc/china_space

A race car traveling at +44 m/s is uniformly accelerated to a velocity of +22 m/s over an 11-s interval. What is the displacement during this time? (Don't solve it) Why is the car being accelerated from +44 m/s to +22 m/s . . . wouldn't it be deacceleration?

I've added a picture that's part of the problem. A sailboat race course consists of four legs defined by the displacement vectors A, B, C and D shown above. The values of the angles are È1 = 420, È2 = 410, and È3 = 270. The magnitudes of the first three vectors are A = 3.7 km, B = 5.3 km...

1.Jack is strolling along the bank of a 1-km wide River when the most beautiful girl materialises on the shore directly opposite him. Fearing she will disappear before he has a chance to establish face-to-face communication, he quickly devises a plan to reach the opposite shore in the shortest...

"The explosive works by stimulating the release of energy from the nuclei of certain elements but does not involve nuclear fission or fusion. The energy, emitted as gamma radiation, is thousands of times greater than that from conventional chemical explosives"...

At first glance, this seems extremely obvious. It says "chinese" on my birth certificate. My "ancestors" moved from China to Singapore. And other features like my "yellow" skin, black hair and black pupils all seem to support this. But if my grasp of scientific theories is correct, the most...

you have heard this before perhaps. its about a runner trying to run d metres. he covers d/2 in t1 second, then half of the distance that is left in t2 seconds, then half of the rest in t3 seconds and so on.as there is always a finite distance left, according to the paradox he can never cover d...

I've been doing a lot of thinking lately about the world and the situation we are in. I do not know how bad racism and separation is around most the world, but I know it is quite alive here in america. We have so many groups that represent the many different people. You've got the NAACP...

In terms of our physical state! We have all seen on TV genetically modified humand with power of the mind the repel people. People with superhuman strength and the ability to dodge bullets with either speed or just because there rock solid! What is the human body capable of? Could we...

Biologically speaking, please define "race". Biologically speaking, please define "race". 1)How many human races (sub-species if you prefer)are there? 2)Of these races, which traits make someone a part of such race? In otherwords, which traits make you black, etc.
