After looking at the standard of Games & Recreation I decided this was better in here! Puzzle: You are given 8 metal cubes with exactly the same dimensions but one is heavier than the other 7. You are given a simple beam balance with standard 2 pans. What is the MINIMUM number of weighings you would need before you can say "That is the heaviest cube"

a charged particle in motion creates an electromagnetic wave. (one property of light)
An electromagnetic wave passing through a conductor creates a charged particle to move through the conductor. (the other property of light).
Ergo since light has both properties mentioned and it moves through space, space must be a conductor.. and it's so cold as to offer zero resistance to light, it must be a superconductor.Right?

Which is more normal... To have your 2nd toe bigger than your 1st toe or vice versa? Personally my 2nd toes are smaller than my big toes and I always thought that was more normal. But, it seems incredibly common for people to have their 2nd toe bigger.

I know Myth Busters did the episode with the "coldest, fastest" way for canned drinks.

But my question is...which would last longer, cubed, crushed or solid blocks of ice in an ice chest, and which would keep the drinks colder.

The coefficient of friction between a box and an inclined plane is 0.35. What is the maximum angle required for the box to stay on the incline and not slide of the incline? if the weight of the object is 100N

some one told me :
100*sin x =0.35*100*cos x
sin x/cos x = 0.35
tan x = 0.35
x = Arctan(0.35)
x = 19.29 degrees

do i need to put the 19.25 in to the formula. like:
100sin19.25 gives me 33.2 degrees, is 33.2 the the maximum angle that the box can stay on the incline plane
