What is the worst natural disaster in recorded history. The natutal disasters we been getting now, how bad are they compared to hundreds and thousands of years ago. All this talk about global warming like the world is ending. They keep saying that records been broken when they only go by what happened about 150 years ago compared to serveral hundred years. extremes like floods, droughts, cold, heat, hurricanes, blizzzards, earthquakes, sunamies,.. the records that they say broken now only compared to 150 years ago. They say that the weather is going crazy because of global warming. I think the weather is just fluctuating.some years are warm, some are cold,, just like a long time ago. ARE THERE MORE EXTREMES OF WEATHER NOW OR BEFORE. IS THE WEATHER GETTING SAFER OR MORE DANGEROUS.

13. You throw a tennis ball of radius R on the floor such that it rolls freely on a flat surface
for some time and then it hits a patch of ice where the coefficient of friction between the
ball and the ice is s = 0. When the ball hits the patch

(a) It continues to roll as before.
(b) It starts to spin
(c) It begins to skid
(d) none of the above

I think the answer is c) is it correct or do you think otherwise. please provide a short explanation with your answer.

So I am supposed to write an experimental procedure for determining the volume of gas generated when 6 grams of a TUMS antacid table is added to 30mLs of 1M acetic acid. Apparently the method of measuring gas volume by water displacement with a buret will not work for this experiment because the experiment may generate too much gas. I am then supposed to indicate what needs to be known exactly. Any idea what this means? Thanks.
