Hi,
Here is the question for today!
Q.54.
Imagine you are in a boat floating in a swimming pool. There is a large stone in this boat. You lift the stone and throw it into the pool. What will happen to the water level of the pool (once it settles down) - Will it remain same? Will it rise? Will it go lower?
Deadline: Wednesday midnight!
Regards,
Manish sir

Hi Sir,
The water level will definately rise.....
The question seems to be very easy, but thats only scary!!!!!
There must be some hidden mystery in it,
Any ways hope i end up with Positive marks!!!:)

Hi Ankita and Ruchira...
You both seem to have forgotten the 'Archimedes' principle that you studied in school! Yes, the same old 'Archimedes' who gave us the word "Eureka"!
When the stone is in the boat, it manages to displace water equivalent to its weight (say x units). However, when it is thrown directly into the water, it manages to displace water equivalent to its volume (say y units). As the stone will be (usually) heavier than water, it follows that x is greater than y. Therefore the water level will (actually) go lower!! In other words, the water level will fall when the stone is thrown into the water.
I am sorry, but Ankita you get -5 and Ruchira you earn -2. I hope this would not discourage you from contributing!
Do keep contributing...some of your posts really give value :)

Manish sir
