a lttle one i have been thinking about




Is there an odd number which is equal to the sum of its divisors? A number which is equal to the sum of its divisors is called a Perfect number. The ancient Greeks knew the first few: 6 is divisible by 1, 2 and 3. 1+2+3=6. 28 is divisible by 1, 2, 4, 7 and 14. And guess what? 1+2+4+7+14=28. Nobody has ever found an odd number which has this property, but nobody has been able to prove that there are none. So this is an unsolved problem which dates back to the time of the ancient Greeks.

 

this is not that great, but you need to know your stuff.

pythagoras's theorem states:

In any right triangle, the area of the square whose side is the hypotenuse (the side of a right triangle opposite the right angle) is equal to the sum of areas of the squares whose sides are the two legs (i.e. the two sides other than the hypotenuse).

or

A^2 + B^2 = C^2

wher C is the hypotenuse and A & B are the other two sides!

so why is A^3 + B^3 ≠ C^3 ???

(≠ means does not equal)

here's a gravity one

-------------------------------------------------------------------

if youre standing in a bus at the front next to the driver

> and the bus is travelling at 40mph

> you then take a jump (directly upwards)

do you? :

a: land in the same place you jumped from

b: end up somewhere further towards the middle/rear of the bus because it was moving?

-------------------------------------------------------------------

sense or confusion i do not know as i have never tried it and am not a physicist
rest assured someone will know the answer, or will go and try it out to find out the answer



p.s. i know that you should stay seated whilst the bus is in motion, but in this case there will be an exception for scientific reason

 

you'll land back where you were because your moving at the same speed as the bus (40mph) unless of course the bus rapidly accelerates/decelerates while you're in the air then you'll land in a place further back/forward respectively.

 

Not mathamatical... BUT if the earth suddenly stopped spinning would we all fall over?

Tyres eventually loose there tread yeah? so this means the rubber must come from the tyre? Where does it go? Why are the side of the roads not covered in little rubber mountains?

 

 

whether the bus is moving or not the floor your standing on isnt. just like a pavement so it would be the same

 

did you take into consideration that the bus weighs approx 7.5T and a human will be around 12st average

and the floor of the bus will be moving, the same speed as the bus 40mph as said

i dont know of any pavements that do 40mph

 

it all went swimingly till level 6

 

Stuck on level 8

 

17 is where it gets tricky (and then 23)

 

Wrong. If the bus is at a constant speed, and you jump up you will begin to decelerate in your forward motion. This means you will land a little further back from where you started as the bus is still at 40mph. The higher you jump, the further back you will land. Jump high enough and you won't even land on the bus

 

i could understand that if it was an open topped vehicle because u would have wind resistance affecting u, but inside i dont think it affects u, if u could get a glass box on a miniture railway travelling at 30mph and have a ball released from the top of the box to the bottom with a camera tracking movement then it would get u an answer, to see if the movement is enough to effect the pull of gravity
