Yes it clearly posed risk to human life but are human lives more valuable than that of the tiger and why not just tranquilize it? Also it was human error which led to the tiger escaping as the enclosure walls were too low and it simply followed its natural instincts.

....but it's something I never learned before.

How do the planets stay on a constant orbit around the Sun, rather than being sucked straight in to it or, conversely, drifting out in to space? How do they remain at a largely constant distance from the Sun?

As per the movie which I now know is true, the inner core of the earth is rotating at a speed faster then the eaths crust. Can it stop rotation? if yes, what will be its effect? Will eath stop producting EM waves, will we be roasted out by suns radiation? what else can happen? And what is the probability of this occuring?

Ok so it says,

Calculate the angular velocity in radians per minute of a Ferris wheel 250 ft. in diameter that takes 45 sec. to rotate once. Express the answer in terms of pi. For an answer I got 50pi/9min and well, I'm not sure its right...
Then it says to calculate linear velocity for the same problem and express it to the nearest foot per min. For this one I got 1178 ft/1min , but I'm not sure it's right either. So you can see my problem here, can you please help me out here, are these answers correct ? ? ?
Well thanks in advance. =)

If plants photosynthesis to convert light energy into sugar, which is used to create energy for the plant, then what is that energy for? Isn't it that plants do not move(only when they move with the air) like we do??

A standard laser pen, for example, has a circular beam about 1mm accross. What's the smallest diameter beam that's ever been created? And can we get any smaller?
I'm not thinking of any particular wavelength of light - it doesn't have to be a visible beam of light.
