The worlds first riddle!

Mark:

WATCH
no change (guess)

"Guess"! My dear Sir, this is a haven of mathematical and scientific exactitude. I guess you never met Albert.

According to Einstein's General Relativity, time is slower in a larger gravitational field. In the mountains, you are farther from the centre of the earth than normal, so gravity is less. Therefore, your clock should run a bit faster, but probably not detectable to human observation.


EGG
heat/cool the water as appropriate (think Galileo thermometer)

Yes, that might work, or you could float a raw egg by putting salt in the water until the density of the water = that of the egg.


ICE CUBE
stays the same - the ice cube displaces its weight in water, so does the water it eventually turns into, and they weigh the same

The water level neither rises nor falls: it stays the same. The reason an ice cube floats is because its volume has expanded during crystallisation.


JOKER
$11.25


RABBIT
45



Ralph:
(What is it with you and water?)

Casino: (Joker)
(x-5)(2)-(10)(2)-(5)=0
x=$11.25

Nice answer.


run rabbit run: it will take rover 135m to catch up with bugs. poor rabbit!

(If three times 45 equal 135, you are a winner)

Please note; No fluffy little bunny wabbits were injured during the construction of this question.



A cage with a bird in it is perched on a swing weighs 4lb. Is the weight of the cage less if the bird is flying about the cage instead of sitting on the swing

Ignoring the fact that if left in an airtight box for long the bird would die, would the answer be different if an airtight box were substituted for the cage


You wanted to sail your model sailboat today. But there is no wind at all and your boat is in the doldrums. Would it be possible to propel your boat by mounting a battery-operated fan on the rear of the boat and directing the fan to blow wind into the sails


Imagine two bridges that are exactly alike, except that every dimension of one is twice as large as the other. For example, the large bridge is two times longer; its structural members are two times thicker, and so forth.

Which bridge is stronger
Or is their strength the same

Bird in the hand??? If tweety is in the cage flappin his wings, it will create the same pressure of down force = to his weight. The weight of the cage wether tweety flaps his wings or sits will remain the same.

Tweety in a vacuumn: in theory there would be a difference. Just don't ask me why.

[size=8]CAGE
no

BOX
no

BOAT
no

BRIDGES
the larger one[/size]

[size=8]I peeked at ralpheb's answers. If airtight means vacuum (I didn't assume that), there is no flight.[/size]

I am sorry you have crossed the Rubicon. I will have to report the matter to Al.


Al has an income which is five eighths that of Bill. Al's expenses are one-half those of Bill and Al saved 40% of his income. What percentage of his income does Bill save

My swag on this will be 37% but I still don't think there's enough info. But what the hell do I know?

As opposed to a WAG, which is unscientific!

from the time the police leaves it will take 3.3 seconds and a total distance of 210m

For the life of me, I can see no connection to:

BTW Mark, may I respectfully suggest a review of your speed may be beneficial. As a much quicker number from me may cause distress. :wink:


Chief Greg Henry and fire fighters Chuck, Darren, Jim, and Vanessa drove the trucks from District 57, responding to a multiple alarm fire from a2k towers. The driver and crew of each truck worked to extinguish the blaze.



Truck 57-1 pumps 750 gallons of water per minute.
Truck 57-2 pumps 1,000 gallons of water per minute.
Truck 57-3 pumps 1,250 gallons of water per minute.
Truck 57-4 pumps 1,500 gallons of water per minute.
Truck 57-5 pumps 1,750 gallons of water per minute.

• Vanessa and her crew pumped 45,000 gallons of water on the fire in a half-hour.

• Chief Greg and his crew worked for 45 minutes, pumping more water than Vanessa's crew but less than Jim's crew did in an hour.

• Chuck and his team pumped the same amount of water as Vanessa's crew in the same amount of time as Jim's crew.

• Darren's crew worked for 45 minutes and pumped the most water on the flames.



Who drove each truck

How much water did each crew use to douse the fire

cops and robbers:

"3.3 seconds"


It is good to see you still have a science of humour.

[size=8]FIRE
1 - Chuck - 45000 gallons
2 - Jim - 60000 gallons
3 - Greg - 56250 gallons
4 - Vanessa - 45000 gallons
5 - Darren - 78750 gallons[/size]

"BTW Mark, may I respectfully suggest a review of your speed may be beneficial. As a much quicker number from me may cause distress."

In two seconds, Mark will be 80m past the cop.
Mark's distance function is 80+40t
The cop's distance function is 1.5t^2
The cop will catch Mark when 1.5t^2 = 80+40t
1.5t^2 - 40t - 80 = 0
Using the quadratic formula:
t = [40 +/- sqrt(1600 + 480)] / 3
t = [40 +/- sqrt(2080)] / 3
Since sqrt(2080) > 40
t = [40 + sqrt(2080)] / 3 = 28.53567

I stand by my answer.

"I stand by my answer."

Now you have me worried!
Let battle be joined on the morrow.

If you had a bag of Canadian coins -- no denomination larger than a loonie. The selection of coins is such that it's not possible to make exactly one dollar with them.

What was the largest possible value of the coins in the bag


How might you tell whether an egg is boiled or not without breaking the shell, or using any equipment other than a flat surface
