Question was:
A fisherman and his young nephew are in a boat on a small pond. Both are wearing life jackets. The nephew is holding a large floating helium filled balloon by a string. Consider each action below independently, and indicate whether the level of the water in the pond R-Rises, F-Falls, S-Stays the Same, C-Can't tell. (If in the first the level Rises, in the second it Falls, and for the rest one Cannot tell, enter RFCCCC)
A) The nephew pops the balloon.
B) The nephew gets in the water, looses his grip on the string, letting the balloon escape upwards.
C) The fisherman lowers himself in the water and floats.
D) The fisherman fills a glass with water from the pond and drinks it.
E) The fisherman knocks the tackle box overboard and it sinks to the bottom.
F) The fisherman lowers the anchor and it hangs vertically, one foot above the bottom of the pond.
I answered SRRSRR
What did I say wrong? Am I being naive somewhere??

I cant see why you should get a violation.
Trolls are the answer.
I had a violation for absolutely no reason, I tried to appeal but no one answered.
I believe that if you get 2 people reporting then it goes on automatic pilot. I dont believe anyone ever checks these things. It would take too long. I had a problem with e.mails for ages, the same automated responses came back, I kept asking IS ANYONE THERE, and the same answer came back.
So I gave up.
There is nobody there. Except the miserable small minded trolls. Take no notice.

RRSSFS
However, the first one could be Can't tell.
Here are the keys to answering these questions:
1) The amount of water displaced by a floating object is equal to the object's weight. The amount of water displaced by a sinking object is equal to the object's size.
2) An object with a density less than water floats and thus displaces an amount of water equal to its weight.
3) An object with a density greater than water sinks and thus displaces an amount of water equal to its volume (which is less than the amount of water equal to its weight).
4) More displacement means the level of the pond rises. Less displacement means the level falls.
A. Rises. The weight increases and the boat presumably continues to float, so the displacement increases. If it is possible that the boat would sink after the balloon pops, then the answer is Can't tell.
B. Rises. Assuming he floats (we don't want him to drown), then the weight increases so the displacement increases.
C. Stays the same. He is floating in both cases so the amount of water displaced is determined by his weight in both cases.
D. Stays the same. The increased displacement due to the weight of the water being drunk is the same as the volume of the water removed from the pond.
E. Falls. Since the box sinks, the amount of water displaced by the box when it is in the boat is more than the volume of the box.
F. Stays the same. This one is tricky. Basically, the weight contents of the boat plus the anchor remain the same and they all continue to float, so there is no change in the displacement.

I don't know why you got a violation, but the first answer should have been R. (The helium balloon made him lighter until he popped it and then he fell heavily into the boat). Did you perhaps mis-spell popped with two o's instead of two p's?

RRSSSS
the displacement of water in the pond due to the weight of the boat and all the stuff in it, is the same if you just dropped all the stuff into the water.

That's very weird. I don't see anything wrong with your answer.
My previous guy got booted off Yahoo! Answers for violating community standards. They didn't even say which of my replies was the offender! I had over 15,000 points and 20 percent best answers. It made no sense. Stupid!

The right answer would be RRSSSS. Wtjui gives the right explanation.

Thats just plain rude...why did you answer a question with a senssible answers...rude and nasty.....lol
YA are getting on my nerves BIG style...i dont think they even read the answers or questions that are then reported....and its annoying!

I wouldn't worry about it, could you not appeal the violation as it seems you did nothing wrong?
