### #91675whats the answer

Posted by on 06 December 2006 - 02:42 PM in General Chat

Since no maximum velocities were never stated, it is assumed that both the aeroplane and conveyor belt have infinite speeds, and are always at the same speed.

Thus, the aeroplane will not have enough air resistance against it to gain an upwards thrust to attain flight.

Edit: No need to assume same speeds(and opposite velocities) as it was stated in the question.

Isn't a ball sliding down a hill the exact same thing as a ball rolling down a hill? How exactly does a ball slip?

If the ball slid down the hill, only one point on the ball would touch the ground throughout the journey.

Where as a rolling ball would have multiple points of contact throughout the journey.

University level physics FTW.

I concur.

Average density would still be lower than that of water, as how else would real life tankers float? especially the ones unassisted by those air bag type things.

Again, basic fluid dynamics. They float because the average density when the boat is upright is less than that of water. Go look up Archimedes' Principle. However, the forces acting on the boat changes when the boat tips to its side. It becomes unstable, and on its side, the density increase because more weight is acting down on the water. Anyway, it's christmas and I can't be arsed arguing my side using archimedes' principle.

As you fill the second tank up, the forces will balance out, and the bouyancy force will not need to be argued.

Well, here's another controversial physics quesiton:

A plane (with horizontally firing engines) is on a giant conveyor belt. This conveyor has a control system that tracks the plane's speed and tunes the speed of the conveyor to be exactly the same (but in the opposite direction).

Will the plane ever take off?

Well for a start a plane is a wood smoothing tool

Only if there is enough air resistance against the Aeroplane.

### #91657whats the answer

Posted by on 06 December 2006 - 11:14 AM in General Chat

That was actually my answer, No, it will not take off as the Aeroplane would be close to stationary, and would not be "cutting through the air" at a fast enough speed (approximately 200MPH iirc) to to leave the ground and fly to the pub.

### #91648whats the answer

Air resistance would still exist.

No.

Nope. That's what I thought at first. But if you did your first option, the ship would sink. And no Google John.

Oil is less dense than water, so the tanker won't sink, no?

QUOTE(paddyb67 @ Dec 21 2006, 11:10 PM)

john mate, gonna just listen for a second. the problem is not a maths one, it is about thinking laterally. the point is that its not the same kind of question like if it takes 1.5 builders to build 1.5 houses in 1.5 days, how long does it take 6 builders to build 6 houses. its seeing if you can think laterally (obv you cant) and the whole point is that you hav e to realise there is a gestation period for laying eggs and therefore a standard unchanging time (1.5 days) for 1 hen to lay 1 egg.

Gestation has nothing to do with laying eggs.

And for the record I am not "mate."

Further more, I am not wasting my time arguing with the likes of you.

### #91749whats the answer

Posted by on 07 December 2006 - 04:59 PM in General Chat

QUOTE(The Wedge Effect @ Dec 7 2006, 04:56 PM)

That depend if you assume all hen take the same length of time to lay an egg or not. If they all do take the same length of time, then it's fair to assume it takes 1.5 days for all the hens to lay six eggs.

Edit: John, it says one and a half hen takes one and a half days to lay an egg and a half. I'm assuming the half a hen lays half an egg. So if it was a whole hen, i.e. 2 hen, it'd lay two eggs in one and a half days.

I edited my post before you posted

### #91813whats the answer

Posted by on 08 December 2006 - 01:40 PM in General Chat

Takes 4 days top lay 6 eggs, as the rate of production per hen per egg is 0.666666666... of an egg.

(No i didnt solve it my genius of a friend did lol)

### #92267whats the answer

so my maths teachers are also incorrect?

As well as proven mathematical rules?

### #92273whats the answer

Posted by on 21 December 2006 - 10:49 PM in General Chat

They could do many things, here is a few.

1) (the most obvious) Fill the other tank.
2) Don't let the boat sail.
3) Put a few fat guys on the other side of the tanker.
4) Let it sail dangerously.
5) Take smaller amounts of oil and make multiple journeys.

Can't be bothered listing more

Thing is, if you want to make a real impact with a bomb by killing people in a Shopping Mall, why the hell would you blow up McCarthur Glen or Braehead?

Do it in London for goodness sakes lol

Infact, do it in The Forge in Glasgow, it could do with being rebuilt, its scabby and ugly.
