I have heard that if you have a 100 pound bag of potatoes or, corn, and you tie a 100 foot rope to it that it would be impossible for a person to pull it.. Even with a car.. How about a 200 foot rope ??
Would any body know anything about this ??

determined by a coin toss, with the outcome of one coin toss having no effect on the others. Each person can see the other players hats but not his own. No communication of any sort is allowed, except for an initial strategy session before the game begins. Once they have had a chance to look at the other hats, the players must simultaneously guess the color of their own hats or pass. The group will win if at least one player guesses correctly and no players quess incorrectly. One obvious strategy for the players, for instance, would be for one player to always guess "red" while the other players pass. This would give the group a 50% chance of winning the game. Can you device a better strategy?

What are the instances you can think of, where a material may absorb electromagnetic energy of a certain frequency (colour) range while ignoring energy coming at other frequencies?

Example:
Plants absorb electromagnetic energy in the form of visible light for photosynthesis, but may not do the same with radio waves or X-rays, which are also electromagnetic waves.
