Brother Spade - Correct - a square or rectangular manhole can indeed slip down a hole. A simple thing explained.


And the hint is????????

Question

2 objects - identical weight -

1 is a 6 inch perfectly round sphere

The other is 7 inch perfect round sphere

Both dropped at identical times from 1 mile from the earth. No wind - pefectly calm.

Do they land at the same time?

Yes, they hit at the same time under the conditions you've stated.

Important hint -

What many women ask men quite often when trying something on

Uhm...."Does this make my ass look big?" 8O

Service hole cover these days YJ. Where ya been?

Do they really call it service hole cover? Great idea, one must use gender neutral language whenever possible. I remember in the 70s (I was living in USA then) a town in Maine changed the name to personhole, it got plenty of ridicule for that.

But service hole sounds quite good.

Question: Why, oh WHY, in this politically correct day and age it is still called a

MANHOLE cover??

Same reason as the province between Sask. and Ontario has retained its name. One that is amazing is why women would allow a "manicure" to endure when no self respecting he man would have one. Who can answer that one.

That's what I'd like to know- it's Goober's game, either play it like he says or find another egotist on another thread to argue with.



keeps one's eyes open.

I aslo wonder if it is possible to have an orgasm while sneezing. Would sneezing increase the orgasm or decrease or increase the sensations due to the momentary drop in blood pressure due to your heart not beating when you sneeze- What effect would a sneezing fit have on orgasms - I think that this is a field that should be studied. Yes I think I will.

Good to see that you have converted to PC - I imagine Harper is pleased with your conversion. I always knew you had a political affiliation.

It was rule that came down from the lesser god Cuticles, the god of fingernails, hooves horns and antlers.

Do you mean Progressive Conservative or Politically Correct? I have never been a Progressive Conservative, but I have always been politically correct.

Anyway, are you saying Harper is politically correct? that doesn't sound like something Harper would go for.

No. You didn't ask for an explanation... :smile:


Does this make me look fat?

Which is heavier, an ounce of gold or an ounce of feathers?
(hint: Trojan Wars)


Why would one be heavier than the other? Or am I missing something?

If you'd have said "pound", I would anwswer feathers, as in avoirdupois vs. Troy.
On the right track. A pound of feathers is heavier than a pound of gold. Precious metals and gems are weighed using the Troy system, a Troy pound is about 372 grams, an avoirdupois pound is about 454 grams. But there are only 12 Troy ounces to a Troy pound, so an ounce of gold, at about 31 grams, is heavier than an ounce of feathers at about 28 grams.

Why would they not land at the same time?
In a vacuum they'd land at the same time, but not in air. The slightly larger sphere has slightly more drag, hence reaches terminal velocity more slowly, and so will be slightly behind the smaller sphere.

That does not answer the question, Dexter. It merely says that red has been the color of danger since times immemorial. But why? Why has color red been a danger signal since historic or prehistoric times? Why did the farmer try to stop the train with his red shirt, rather than waving his gray hat? Wouldn’t that have been easier than removing his shirt and waving it in the air?

Our ancestors were not dummies; they no doubt observed something about the red color that made them decide that it indeed is the color of danger. While they may not have understood physics, they did observe some property of red color that fixed red as the color of danger.

So the question stands, why is red the color of danger, and green the color of go ahead?
