Is it possible that so many people having the exact same experience can all be victims of missinterpretation? Is there really that much swamp gas going around?

If a boat travels 100 meters due north while the wind exerts a forece of 500 newtons towards the northeast, How much work does the wind do?

I know that work is either F.D or ||F||cos(theta)*D, but how do you know what angle "northeast" makes?

I found a pile of several hundred, perhaps several thousand, 1-3 millimeter in diameter yellow spheres in my backyard. They look like they could be eggs, but the shear volume of the pile seems to preclude any one creature having generated them. They are half opaque yellow and half clear. They squish when stepped on but the outer shell is not soft - it is firm like a ripe berry.

Some have popped open leaving nothing but an opaque yellow shell. They could be some sort of fertilizer granule? But I have no idea how they would have gotten there if they are. I took a large number - easily several hundred into my house in a jar for observation and as far as I can tell none of these spheres has done anything yet over the past several hours.

Any help would be great! Thank you!

A car is traveling down a one lane country road at 21 miles/hour. Up ahead a truck is traveling the opposite direction at 15 miles/hour. If they are 0.20 miles apart, how long will it be before they run into each other assuming neither one of them slows down?

I mean, this 'special relationship' has to lead to somewhere. Also, Alaska is not physically part of the USA, but is still considered USA soil. Why can't Britain?
